RE: [PHP-DB] Password decryption
Hi,
Note from the manual:
PASSWORD() encryption is one-way (not reversible).
Also note:
===
Note
The PASSWORD() function is used by the authentication system in
MySQL Server; you should not use it in your own applications.
For that purpose, consider MD5() or SHA1() instead. Also see RFC 2195, section
2 (Challenge-Response Authentication Mechanism
(CRAM)), for more information about handling passwords and authentication
securely in your applications.
===
The way to do it is to encrypt the response password from the logon and compare
the encrypted versions; rather than decrypting for
the compare.

Subject: [PHP-DB] Password decryption
Hi,
I'm junior in PHP and stuck on Encryption.
I have encrypted password using SQL :
$query = insert into user (userid,password,) values
('$username',Password('$pass'));;
Which is working perfect. Now I'm working on Login page where
I have to compare passwords.. As password in database is
encrypted so I need to decrypt it back for compression. I
have tried the flowing but not working.
if ($pwd != Password($info['password']))
{
echo(-);
//header(Location: abuse.php);
}
and
if ($pwd != $info(Password(['password']))
{
echo(-);
//header(Location: abuse.php);
}
Could any one please help..
Thank you

the password is encrypted one way ( usually md5() ) so you must compare
the encrypted hashes

[PHP-DB] Help with MySql float
Hi Guys, When inserting a value like 123567.8956 in my table it is rounding it to 2 decimal place. The field type is set as float. Can anyone tell me why it's not taking all the decimals? and How to insert the number with all the decimals? Thanks Velen -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Not very PHP related. Anyway... It depends on your version of MySQL. Check the documentation for Numeric Types. It says you can specify the number of decimals you want to store, something like FLOAT(max_digits,precision). If you need more precision, there's also the DOUBLE PRECISION. If your MySQL column is specified for higher precision already, then it could be a PHP issue. Is this the case?

It's a one-way encryption method, so you won't be able to see the
plain-text equivalent of the password again, but you can use this when
testing a login:
SELECT * FROM user WHERE userid='.$username.' AND
password=PASSWORD('.$pass.');
Also, to correct your $query above, some things to note:
PASSWORD is a reserved word in MySQL, so you shouldn't name
any columns or databases as such.
You have a comma after `userid,password,` in your column bracket.
With PHP, you shouldn't end your MySQL query with a semicolon.
The code needs it to terminate the line, the query doesn't.

That's a MySQL question, not a PHP question, but my guess is that
the column is set as FLOAT(x,2) (where x is any real number). Try
changing that to FLOAT(10,4). The first number is everything to the
left of the decimal, while the second is the number of places to count
after the decimal.

The first number is everything to the left of the decimal, while the second is the number of places to count after the decimal. Also note that a float type is not guaranteed to come back the same as it goes in (and this will also affect maths operations) - so if you need 4 decimal places, then use decimal or numeric as the data type. http://dev.mysql.com/doc/refman/5.0/en/numeric-types.html MySQL performs rounding when storing values, so if you insert 999.9 into a FLOAT(7,4) column, the approximate result is 999.0001. The DECIMAL and NUMERIC data types are used to store exact numeric data values. . These types are used to store values for which it is important to preserve exact precision, for example with monetary data. This is the same in any db, it's not a mysql specific behaviour. -- Postgresql php tutorials http://www.designmagick.com/ -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DB] Importing CSV files to MySql Db issue.
I am not using spaces for closing. Every field is tightly packed with comma only. No spaces, no semicolon. The reason I used space is if I use space at least 3 or 4 fields get uploaded but not all. But we can ignore space for now as it happened earlier. I am using the CSV import option from MySql admin.
