[Mcrypt-users] newbie questions

[Aaron B. <bo...@gm...>]

Hi,

I am trying to encrypt a file using aes 128 in cbc mode, using pkcs7
padding, with a specified
16 byte initialization vector.

I believe that pkcs7 padding is on by default. And that rijndael-128
mode is equivalent to aes 128.

How may I set the initialization vector?

Thanks!!
