A great demonstration with images at

avoid ECB mode. Schneier's _Applied Cryptography_ goes into why, but
basically it has to do with the fact that once someone knows the
plaintext of a given block, that block will always be transparent to
them.

In AES encryption/decryption block size is always 16 bytes and not
depends on key size.
Key size fo
This may or may not be a useful example:
static int

len) {
int c = 0; // Temp counter
char tmp[8] = { 0 };// Temp buffer
char *ptr = out;// Pointer to out buffer
while(c < len)
{

Until i buy one of the books i have a question, which may be very easy
to you, but, now i really need the ansver:
i want to encrypt and decrypt strings, now i'm using the ecb encryption
of openssl/aes.h
and it looks the encrypted block length depends on the key, or the
encrypted msg has an \0 in.
Hi,
There is another book from O'Reilly: "Network Security with OpenSSL",
from John Viega, Matt Messier and Pravir Chandra.
Hope it will help ;)

Hi!
I'm newbie at using openssl libs, and i need a documantation where i can
read about the function of libssl,
for example: i want to use aes for message encrypting, and i have to
know things like what length of key can i use..
I tried some keys and i found that the key length must be 16 or 32byt
