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:

vScVj7ieDfqg7a3TczIWghXtK7X6sB30Ao5c0klQvPunYaiTPMMCHfBQKYXfad72BL4=

f97/zGwNCW1FNAuutqinrkgyAMvk6BTKHLKZXl9ggxYosC3/zOGz9eJZ9PTn1Z3erJ8=

lt3QT+aeM+8HQMAIwxdEjTfCQ4viWv5x1UmUnLUvkCStXkYsa+d27NO/b19Q0wC3/uI=

My program works like this:

$ aes keyfile < infile > outfile

$ aes -d keyfile < infile > outfile

Regards
Stefan

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

LibreSSL can't handle it either. I guess no problem because who
uses them, when there are easier tools, like mine, available. ;-)

Works quite good with larger data. :-)
