Hi all,
 
I just want to know if your AES encryption program is compatible with mine.
 
Can you please test that.
 
Here is the encryption key:
 
d33572d668cb7b8f5323bf160309c98d85a9668e26f6df9c667a50982de40123
 
And here is a message, encrypted with that key 3x times:

lt3QT+aeM+8HQMAIwxdEjTfCQ4viWv5x1UmUnLUvkCStXkYsa+d27NO/b19Q0wC3/uI=
 
My program works like this:
 
$ aes keyfile < infile > outfile
 
$ aes -d keyfile < infile > outfile

Mmmmhhh, maybe my OpenSSL version is too old or I do something wrong. :-(
