Key will be upward zero-padded to nearest supported key length.
AES supports 3 key lengths: 128, 192 and 256 bits.
So simply give the encrypt() function 256-bit key.

 AFAIK, the support of mhash and mcrypt was dropped from the recent version
 of the module, so the AES 256 functionality can be only provided by OpenSSL?

Builtin AES supports 256-bit keys too.

[GENERAL] Using pgcrypto with AES-256 bits?

2005-04-30 Thread Stas Oskin








Hello.



I
tried the pgcrypto contrib module with the AES default encryption. It works
pretty nice, but I understand that it's using 128 bit key strength. Is there
any built-in support for the 256 bit key strength? Or it should be used via
external libraries?



AFAIK,
the support of mhash and mcrypt was dropped from the recent version of the
module, so the AES 256 functionality can be only provided by OpenSSL?



Thank
you.
