mcrypt and key bytes

[Marek Muszak]

Hello,

I try use mcrypt but I want to use key in bytes, not in string. Encrypt
text will be decrypt in Delphi with function where key is 16byte not string.

How can I do this.

Thanks for any help.

best regards
Marek

Any Key String is hashed by mcrypt and this hashed value (16 bytes) is
internally put in key. I don't know how mcrypt do this but I have to put
the same 16bytes in Delphi function.

A 16 byte string is a 16 byte string in any language, regardless of what it
contains.
