[PHP] MCrypt not decrypting simple text
I'm using MCrypt and I have two very simple functions. All I'm doing is
giving the function some text and a password, it encrypts the text and saves
it as a text file on the server. Then I at some later time run another php
file which decrypts using the decrypt function given the text and the SAME
password as the first time and all I get is garbage. What am I doing wrong?
What do I need to change so that I can get this to work the way I described?
function aes_128_encrypt($text,$password) {
$size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC);
$iv = mcrypt_create_iv($size, MCRYPT_DEV_RANDOM);
$text .= chr(3).chr(3).chr(3);
return bin2hex(mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $password, $text,
MCRYPT_MODE_ECB, $iv));
} // End of function
and
function aes_128_decrypt($encrypted_text,$password) {
$size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC);
$iv = mcrypt_create_iv($size, MCRYPT_DEV_RANDOM);
return mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $password, pack(H*,
$encrypted_text), MCRYPT_MODE_ECB, $iv);
} // End of function

[PHP] MCrypt resource limits?
Hi list, Yesterday I noticed one of the sites I had created was running really slow. Yet all the other sites on our webserver were running great. I had our network admin look at the cpu, ram usage, etc of the webserver and everything looked fine. Finally I just recommended we stick Xdebug on there to find out what the exact problem was. It boiled down to my encryption wrapper object. I guess there were too many MCrypt resources open at once. I'm not really sure of the real problem, but when I switched around some code to avoid unnecessarily loading initializing the resource, the site was zippy again. As I was developing locally everything was fine because it was just me hitting the site. When I pushed it to the server though there was quite a bit of traffic to it. So my question is, are there limits in PHP to how many resources can be opened? What about limits to how many MCrypt resources you can have open? This specific instance was a stupid mistake on my part, but I just want to know for future reference. Thanks!

Is it possible to set the key length for mcrypt with the cipher Blowfish? Specifically to lets say 128 bits? mcrypt_get_key_size returns int but is it bytes bits? Maybe I could do with openssl? Ideas and thoughts very welcome. Thanks, Scott

Is it doing some padding or something? When I encrypt/decrypt same script it

Look at trim(). And your right it does have to do with using ECB.

Re: [PHP] Mcrypt 3DES encrypt/decrypt Help
I've never used the mcrypt functions, but from a quick read of the documentation I think you are using a 384 bit key!... Each letter in your key string is a 8bit ASCII character, and since you have 48 chars, you have 8*48 bits. The documentation says: Key is the key with which the data will be encrypted. If it's smaller that the required keysize, it is padded with '\0'. It is better not to use ASCII strings for keys. It is recommended to use the mhash functions to create a key from a string. and gives the example: $key = This is a very secret key; In that example the key is 25 bytes long, therefore 200 bits long, and then padded with \0s. If you want your key to represent the hex of the key then I believe you must use pack(), or one of the user comments on the bin2hex() help page (namely the hexbin() function).

[PHP] mcrypt problem under Windows
Hello, I have a problem with mcrypt library. I'm using Apache 2.0.54 under Windows and PHP 4.3.3. I tried to run an example from PHP site [1] but it is not working - the decrypting is doing nothing. I searched the web and found only that I need to download newer version of libmcrypt.dll (but I'm unable to find version 2.5.6 or newer, only older ie. from [2] or sources). Some other person in this groups archive suggested to use mycrypt.dll instead of default php extension but I didn't understant his idea. I would be very grateful for the solution.

Hi, Our website uses mcrypt functions to encrypt and decrypt passwords stored in the PostgreSQL database. The website encrypted/decrypted passwords flawlessly under PHP 4.0.4, however, we recently upgraded the server that the website is stored on to PHP 4.2.3. Since then, each time a password is encrypted/decrypted using any of the mcrypt-functions, the following error displays even though the code was untouched: Fatal error: generic_init failed in /home/httpd/html/domainsunderdevelop/include/class.databaseconnection.php on line 498 Line 498 on class.databaseconnection.php is: $NewString = mcrypt_cbc( $this-CIPHER, $this-KEY, $RawString, $Mode, $iv ); We installed libmcrypt 2.4.9 after upgrading PHP to 4.2.3.

[PHP] PHP - MCRYPT - CBC - IDEA
Hi all,
I'm looking for some information, rearging mcrypt.
Now, I've been through the normal channels, I've been going in in cercles.
I need to recreate this perl script in php :
sub cryptage
{
use Crypt::CBC;
$key = SuperFreak;
my $action = shift;
my $string = shift;
my $c = new Crypt::CBC($key,IDEA);
if ($action == 1) { #- crypt
return $c-encrypt_hex($string);
} else { #- decrypt
return $c-decrypt_hex($string );
}
As you can notice it uses CBC, and IDEA.
MCRYPT_IDEA (non-free) is all I get from the net, where can I purchase it ?
Or better yet, how can I recreate this function in PHP ?
even a simple Look this way would help.
Thanx
Frantzcy

Sorry about that. I must have read your message wrong. I have used mcrypt, but not with IDEA or cbc. Are you locked into that particular cipher? Can you not use a different one?

[PHP] Encryption in PHP - mcrypt and alternatives
I have a need for an encryption program that can encrypt/decrypt data. I previously had a programmer build me a C program that compiled and runs on the command line, which I would then call via PHP. We are experiencing with this however, a 5-7% fail rate on the decryption - not acceptable for the application. At this point the programmer is blaming the mcrypt libraries for the problem - I suspect not, but not being a C programmer, cannot refute this. So, the next step was to use Mcrypt Libraries through PHP. They are not compiled into our PHP version - 4.1.2, and we cannot re-compile PHP. First reason is that the server runs Plesk 5, and the original compile was done off server (you know - host provider - install via disk image, etc). Bottom line, PHP cannot be re-compiled with mcrypt. Finally, I tried dynamically loading he libmcrypt.so library - compiled just this morning specifically for this application. No go. It would not load from the php.ini file, and when I tried to load it on a page, using the dl() function - I got the error: Invalid library (maybe not a PHP library) 'libmcrypt.so' So at this point I am at a total loss. I cannot hash the data, I need it to be decrypted at another point as well. So, I guess I am asking this: 1. Is there any reasonably priced C programmer that would like to talk to me about fixing/re-writing this encryption program. 2. Have I overlooked anything with the dynamic loading of the mcrypt libraries. And 3. Am I missing another alternative for securely encrypting/decrypting data in PHP? Short of re-compiling or such.

[PHP] mcrypt pdflib configuration
I've already posted this question in comp.lang.php but no one seemed to have an answer to it. So I've got PHP to recognize mcrypt and pdflib in the phpinfo() output, but trying to use any of the functions fail with ...undefined function called... There aren't any configurable files with either distro and neither mention php.ini settings need to be made. Restarting the apache server does not fix this and no errors are reported while starting. The most recent stable releases Apache 2.0.49 and PHP 4.3.6 are being used with mcrypt 2.4 (stable, but 2.6.4 is most recent) and pdflib 5.0.3p1 (most recent stable release) libraries, running on Windows 2003 Server Enterprise with all updates applied. I picked up a copy of Visual Studio .NET Enterprise but am also stumped of how to compile these functions from source which I would prefer to do at this point.

Re: [PHP] mcrypt don't work.
Francesco, mcrypt_ functions rely on a PHP extension, your syntax look ok, PHP is telling you that it could not load the required extension (module). the following page from the PHP manual tells more about what you need in order to use mcrypt_ functions: http://nl2.php.net/manual/en/ref.mcrypt.php I also noticed that you are trying to use the IDEA encryption algorithm; afaik this is only free for use non-commercial use... although you may not care ;-) [EMAIL PROTECTED] wrote: Hi all, i've problem with mcrypt_cfb function.

Re: [PHP] mcrypt don't work.
Have you tried to check if PHP has been compiled with mcrypt? try this on a page ?php phpinfo(); ? Look for mcrypt directives, if not there you need to download it and compile it like so. http://mcrypt.sourceforge.net Get both the libmcrypt and mcrypt compressed archives from command prompt on linux... cd /path/to/libmcrypt.xx.tar.gz gzip -dfrv libmcrypt.xx.tar.gz tar -xvf libmcrypt.xx.tar cd libmcrypt.xx/ ./config --disable-posix-threads make make install now do the same for mcrypt cd /path/to/mcrypt.xx.tar.gz gzip -dfrv mcrypt.xx.tar.gz tar -xvf mcrypt.xx.tar cd mcrypt.xx/ ./config --disable-posix-threads make make install now you need to compile php for mcrypt support cd /path/to/php-4.xx ./configure --with-mcrypt=/path/to/libmcrypt/ make make install simple, now if your using apache on windows you need to get the windows executables from mcrypt.sourceforge.net Also if mcrypt is already installed simple do a find find / | grep libmcrypt from a command prompt to find the libraries, if you cannot find it them install it, or just re-compile php to include support. Hope this helps, it took me awhile to figure it out too. Jas -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] mcrypt and PHP to encrypt values to be passed to differend server
Hello!
I'm trying to use mcrypt to encrypt some values (login and password) I have
to pass from one website to another.
I thook this code from the php.net website as an example:
?php
/* Open the cipher */
$td = mcrypt_module_open ('rijndael-256', '', 'ofb', '');
/* Create the IV and determine the keysize length */
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_DEV_RANDOM);
$ks = mcrypt_enc_get_key_size ($td);
/* Create key */
$key = substr (md5 ('very secret key'), 0, $ks);
/* Intialize encryption */
mcrypt_generic_init ($td, $key, $iv);
/* Encrypt data */
$encrypted = mcrypt_generic ($td, 'This is very important data');
/* Terminate encryption handler */
mcrypt_generic_deinit ($td);
/* Initialize encryption module for decryption */
mcrypt_generic_init ($td, $key, $iv);
/* Decrypt encrypted string */
$decrypted = mdecrypt_generic ($td, $encrypted);
/* Terminate decryption handle and close module */
mcrypt_generic_deinit ($td);
mcrypt_module_close ($td);
/* Show string */
echo trim ($decrypted).\n;
?
I put this in the page starting from:
?php
$adminlogin = $row1[adminlogin];
$adminpw = $row1[adminpw];
// both are queried from a database
$td = mcrypt_module_open ('rijndael-256', '', 'ofb', '');
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_DEV_RANDOM);
$ks = mcrypt_enc_get_key_size ($td);
$key = substr (md5 ('a key fsfqz'), 0, $ks);
mcrypt_generic_init ($td, $key, $iv);
/* Encrypt data */
$encryptedlogin = mcrypt_generic ($td, $adminlogin);
$encryptedpassw = mcrypt_generic ($td, $adminpw);
mcrypt_generic_deinit ($td);
mcrypt_module_close ($td);
?
a href=destinationpage.php?login=?php echo($encryptedlogin);
?password=?php echo($encryptedpassw); ? target=_blanklink/a
In the destination page (destinationpage.php, on a different server) I have
this:
$td = mcrypt_module_open ('rijndael-256', '', 'ofb', '');
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td),
MCRYPT_DEV_RANDOM);
$ks = mcrypt_enc_get_key_size ($td);
$key = substr (md5 ('a key fsfqz'), 0, $ks);
mcrypt_generic_init ($td, $key, $iv);
/* Decrypt encrypted string */
$login = mdecrypt_generic ($td, $login);
$login = trim ($login);
$password = mdecrypt_generic ($td, $password);
$password = trim ($password);
mcrypt_generic_deinit ($td);
mcrypt_module_close ($td);
and then an echo($login - $passwordbr); to check if the values are
correct.
But they are not!!
What am I doing wrong?? Is it because both are on a different server?
I would very much appreciate your help. Or if someone has an other good way
of encrypting values, please let me know!
Thanks!!!
Mark.

You will need to pass the $iv which kinda defeats the object of it, or
use a null one. Here is a class I use for this which also corrects the
string lengths as decryption will usually have a few /0 tacked on to
make it a block size:
class encrypt_class{
var $secret;
function encrypt_class(){
$this-secret = 'choose your own pass phrase here';
}
Function encode($id){
$eid = $iv = 0;
$len = strlen($id);
$id = $len.'-'.$id;
$td = mcrypt_module_open(MCRYPT_TripleDES, , MCRYPT_MODE_ECB, );
$key = substr($this-secret, 0, mcrypt_enc_get_key_size ($td));
$iv = pack(a.mcrypt_enc_get_iv_size($td),$iv);
mcrypt_generic_init ($td, $key, $iv);
$eid = base64_encode(mcrypt_generic ($td, $id));
mcrypt_generic_deinit($td);
return $eid;
}
Function decode($eid){
$id = $iv = 0;
$td = mcrypt_module_open (MCRYPT_TripleDES, , MCRYPT_MODE_ECB, );
$key = substr($this-secret, 0, mcrypt_enc_get_key_size ($td));
$iv = pack(a.mcrypt_enc_get_iv_size($td),$iv);
mcrypt_generic_init ($td, $key, $iv);
$id = mdecrypt_generic ($td, base64_decode($eid));
$len = strtok($id,'-');
$id = substr($id,(strlen($len)+1),$len);
mcrypt_generic_deinit($td);
return $id;
}
}
//usage
$password = 'password';
$name = 'me';
$mesage[0] = $password;
$message[1] = $name;
$serial = serialize($message);
$enc = new encrypt_class();
$enc_message = $enc-encode($serial);
//send message ?enc_message=$enc_message
//next page
$enc = new encrypt_class();
$serial = $enc-decode($_GET['enc_message']);
$message = unserialize($serial);

Hello Vladimir, you can run phpize in the mcrypt extension directory in your PHP source code, then copy the .so file to your PHP extension dir and either add an extension line to your php.ini file or use dl to load the extension at run time. Generally I just compile it in at PHP configure time as you need write access to the PHP extension directory anyway.

[PHP] mcrypt not fully decrypting?
Hi,
I'm going to start encrypting credit cards with the mcrypt functions. I
encrypted the credit cards like so:
$key = 'test';
$cc = 1234567890123456;
$td = mcrypt_module_open ('tripledes', '', 'ecb', '');
$key = substr ($key, 0, mcrypt_enc_get_key_size ($td));
$iv_size = mcrypt_enc_get_iv_size ($td);
$iv = mcrypt_create_iv ($iv_size, MCRYPT_RAND);
// Initialize encryption handle
if (mcrypt_generic_init ($td, $key, $iv) != -1) {
// Encrypt data
$ciphertext = mcrypt_generic ($td, $cc);
mcrypt_generic_deinit ($td);
// Reinitialize buffers for decryption
mcrypt_generic_init ($td, $key, $iv);
$plaintext = mdecrypt_generic ($td, $ciphertext);
// Clean up
mcrypt_generic_deinit ($td);
mcrypt_module_close ($td);
print font face=Arial size=2bCiphertext:/b $ciphertextBr;
print bPlaintext:/b $plaintext/font;
}
Sometimes, when I decrypt a cc it contains binary data...it's not fully
decrypted. There's some plaintext in it and there's also binary. Does
anyone know why this happens or how I can fix it?
Thanks,
Tyler

[PHP] mcrypt installation problems
Can anyone point to information on how to install mcrypt support for PHP. I tried the PHP mcrypt pages but they are quite lacking in details. I downloaded libmcrypt and got that installed fine. I also downloaded mcrypt (do I really need it?) but that wouldn't configure. It complains that: checking for libmcrypt - version = 2.5.0... no *** Could not run libmcrypt test program, checking why... *** The test program compiled, but did not run. This usually means *** that the run-time linker is not finding LIBMCRYPT or finding the wrong ... I tried compiling PHP with --with-mcrypt=/usr/src/mcrypt-2.6.3/ (the locate of the mcrypt source files) but that gave me an error when I did make: cc1: warning: changing search order for system directory /usr/local/include cc1: warning: as it has already been specified as a non-system directory /usr/src/php-4.3.0/ext/mcrypt/mcrypt.c:229:1: warning: MCRYPT_FAILED redefined In file included from /usr/src/php-4.3.0/ext/mcrypt/mcrypt.c:34: [...] Questions: 1- Do I need both libmcrypt AND mcrypt? 2- What is the installation procedure?

Re: [PHP] mcrypt installation problems
You need only libmcrypt, mcrypt is a command line program that is intended to replace the Unix crypt program. To build the mcrypt binary you need mhash and libmcrypt, for PHP unless you want mhash you need only libmcrypt.

Re: [PHP] mcrypt
Actually you should be able to get mcrypt working with PHP on Windows (mcrypt is not distributed with PHP because of the legal issues surrounding exporting encryption). If you visit the PHP manual page for mcrypt at http://www.php.net/manual/en/ref.mcrypt.php you will see the following under Requirements: Windows users will find all the needed compiled mcrypt binaries here (http://ftp.proventum.net/pub/php/win32/misc/mcrypt/). You should be able to add this as a php extension in your windows php.ini file and then mcrypt functions should be available to you under windows, there is no need to use other software. I'm glad to see mcrypt support for windows because it finally allows me to use my favorite PHP encryption library between both platforms.

[PHP] mcrypt 2.4.x - trouble with small data fields?
On my current project I am saving personal info into a MySQL database
for later retrieval. I have discovered that I have trouble with a few
specific data entries, though the other ~20 work fine. The two I have
trouble with are a char(2) and a varchar(4) field, the smallest ones in the
table, and they return garbage when decrypted. Is there a minimum field
size for using mcrypt? Sample code:
// to encrypt, init once
$mykey = 'keytext';
$td = mcrypt_module_open(MCRYPT_TRIPLEDES,'', MCRYPT_MODE_ECB, '');
$iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($td), 1234567890);
$ks = mcrypt_enc_get_key_size ($td);
$key = substr(md5($mykey), 0, $ks);
mcrypt_generic_init($td, $key, $iv);
(...)
$CreditCardExpMonth = mcrypt_generic($td, $_POST['Credit_Card_Exp_Month']);
(...)
// then save to database as part of insert query
If I save/retrieve the fields to/from the database w/o encryption they
save retrieve fine. This field is two digits ('02', '11', etc.). The
other is the year (4 digits).
// to decrypt
// I wrote a function to truncate the returned string at the
// first \0 since mcrypt's decrypt pads the result
echo mydecrypt($data['CCExpMonth']);
function mydecrypt($enc) {
global $td;
$str = mdecrypt_generic($td, $enc);
$pos = strpos($str, \0);
if ($pos !== false) {
$str = substr($str, 0, $pos);
}
return $str;
}
Also as long as I'm posting, mcrypt_generic_deinit() seems to be
undefined on my system? Is that an mcrypt issue or an interaction between
PHP 4.1.2 and mcrypt 2.4.x?

[PHP] mcrypt vs. libmcrypt
I saw on Google search result about PHP and mcrypt. I read the manual on http://php.net/mcrypt and it spoke about downloading libmcrypt and use the php configure option, --with-mcrypt= for libmcrypt-2.x.x. So, on the Google search result, one of hte posting talk about using both the libmcrypt and mcrypt. So, what is the difference between these two? Do I need to install both of them or just libmcrypt??

RE: [PHP] mcrypt
Good day, i started using crypt() then changed to mcrypt() which was not any good cause of the high ascii characters then i read about converting the high ascii characters to hex . Is this the ideal way to encrypt passwords or is their something better. The crypt() function will generate a standard UNIX crypt password that other programs can understand. UNIX crypt has some limitations (only using the first 8 characters is the major one) but it's good enough for most people and is probably the most widely supported. If you want something stronger, you can use md5(). The examples on php's documentation for this function should help you if you're interested in having other programs use it (to have it the right format and length).

Re: [PHP] mcrypt
If all you need is some generic encryption that doesn't require mcrypt, you
might want to take a look at a crypto extension I wrote called
cryptopp-php. It does everything that the mcrypt extension does and might
be a touch easier to use as far as syntax and such goes. (Plus, it works on
Windows if you're into that sort of thing.) It's fairly stable at the
moment, and doesn't have the memory allocation problems.
See http://www.tutorbuddy.com/software/, and
http://www.tutorbuddy.com/software/cryptopp/ for the manual.
(I hate the shameless plugging, but the more people who use my extension the
easier it is for me to debug...)

Re: [PHP] mcrypt
Cross posting this with php-dev might not be the best idea. The dev list is
not for support unless you are trying to code part of the php source.
So this is only failing on the decrypt side of the code?
Memory allocation error does not sound like a problem specific to this
function. All the other errors are just because mcrypt_generic_init failed.
Try only encrypting in one script and then only decrypting in another script
and see what happens.
What are the specs of your system? compile options, platform, etc.?

Subject: Re: [PHP] mcrypt
Rather than tease you with hints I'll give you some working code ;-)
Documentation for practical usage of mcrypt is weak. I agree.
?
// crypto.inc
$key = secret key crap;
function hex2bin($data)
{
$len = strlen($data);
return pack(H . $len, $data);
}
function encrypt($string, $key)
{
// version 2.4.x of lib mcrypt
$td = mcrypt_module_open (MCRYPT_TripleDES, , MCRYPT_MODE_ECB, );
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size ($td), MCRYPT_RAND);
mcrypt_generic_init ($td, $key, $iv);
$crypted = mcrypt_generic ($td, $string);
mcrypt_generic_end ($td);
return bin2hex($crypted);
}
function decrypt($string, $key)
{
//version 2.4.x of lib mcrypt
$string = hex2bin($string);
$td = mcrypt_module_open (MCRYPT_TripleDES, , MCRYPT_MODE_ECB, );
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size ($td), MCRYPT_RAND);
mcrypt_generic_init ($td, $key, $iv);
$decrypted = mdecrypt_generic ($td, $string);
mcrypt_generic_end ($td);
return trim($decrypted);
}
?
usage:
?
include (path/to/crypto.inc);
$secret = meet at secret place;
$encrypted = encrypt($secret, $key);
print original: . $secret . br;
print encrypted: . $encrypted . br;
$decrypted = decrypt($encrypted, $key);
print decrypted: . $decrypted . br;
?
Note: if you are encrypting really secret crap like credit card numbers or
something of that nature then NEVER include the key anywhere in your code.
Make a form where you have to type it in or something in order to display
the results.

Subject: [PHP] mcrypt
Hello,
I am getting some odd errors trying to get an encrypt/decrypt
process to
work. Looking at the manual examples and some other literature, I
have
tried
the two approaches listed below. For each, I get a sometimes-works,
sometimes fails result. The manual entry has a string of user notes
with
problem like mine, but I still have problems.
Server API Apache
mcrypt
mcrypt support enabled
version 2.4.x
Supported ciphers twofish rijndael-128 rijndael-192
rijndael-256
saferplus rc2 xtea serpent safer-sk64 safer-sk128 cast-256 loki97
gost
threeway cast-128 des tripledes enigma arcfour panama wake
Supported modes ofb cfb nofb cbc ecb stream
--]
The first attempt used the following code:
--
?php
$key = this is a secret key;
$input = Let us meet at 9 o'clock at the secret place.;
$td = mcrypt_module_open ('tripledes', '', 'ecb', '');
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size ($td),
MCRYPT_RAND);
mcrypt_generic_init ($td, $key, $iv);
$encrypted_data = mcrypt_generic ($td, $input);
$decrypted_data = mdecrypt_generic ($td, $encrypted_data);
mcrypt_generic_end ($td);
echo key:
$keybrinput:$inputbrencrypted:$encrypted_databrdecrypted:$decrypted_da
ta;
?
--]
This resulted, at first, in key: this is a secret key
input:Let us meet at 9 o'clock at the secret place.
encrypted:\ºþêTÏ' áz(v¹FýaõFËU³æç SäÇÚÖz ßù5Qì±_T-:Í
decrypted:Let us meet at 9 o'clock at the secret place.
BUT after I refreshed/reloaded a couple of times, I got this:

[PHP] Mcrypt Function - New to it
Hi there..some what a new programmer when it comes to all this. I'm trying to encrypt some data and then decrypt it. It doesn't have to be high bit encryption just something simple like 3DES. But I keep getting it wrong. Any help would be greatful. Here's the piece of code: $iv = mcrypt_create_iv (mcrypt_get_iv_size (MCRYPT_3DES, MCRYPT_MODE_ECB), MCRYPT_RAND); $key = md5(Secret Key); $sample2 = Hello; $lockdata = mcrypt_encrypt (MCRYPT_3DES, $key, $sample2, MCRYPT_MODE_ECB, $iv); echo $lockdata\n; $text = mcrypt_decrypt (MCRYPT_3DES, $key, $lockdata, MCRPYT_MODE_ECB, $iv); echo $text\n; -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Mcrypt Function - New to it
Hi
Here are a couple of functions that should help to get you started, iv is
set to all 0's so it does not have to be passed around or stored in
sessions. It is base64 encoded so it can be stored or passed to the browser.
Function Code_id($id,$password){
$eid = 0;
$td = mcrypt_module_open (MCRYPT_TripleDES, , MCRYPT_MODE_ECB, );
$iv = pack(a.mcrypt_enc_get_iv_size($td),$iv);
mcrypt_generic_init ($td, $password, $iv);
$eid = base64_encode(mcrypt_generic ($td, $id));
mcrypt_generic_end ($td);
return $eid;
}
Function Get_id($eid,$password){
$id = 0;
$td = mcrypt_module_open (MCRYPT_TripleDES, , MCRYPT_MODE_ECB, );
$iv = pack(a.mcrypt_enc_get_iv_size($td),$iv);
mcrypt_generic_init ($td, $password, $iv);
$id = mdecrypt_generic ($td, base64_decode($eid));
mcrypt_generic_end ($td);
return $id;
}
