Hi,

Need to encrypt file with 512bit (or higher) key. Looking at DCPCrypt but seems that none of them can do that. Any advice?

Regards

=================================
DCPcrypt v2 contains the following ciphers and hash algorithms:

Is there nothing that suits your needs? If not, patch are always welcome ;-)

Thanks Graeme! My fault that I didn't read documentation. I checked ciphers source looking for comments at top of the unit. BTW: What does it mean "non-commecial"? Algorithms are licensed or FPC implementations? My tool will be free and open source with donate option

Hello,

Which is the reason for such a big symmetric key size ?

I guess you should be fine then, but I'm no lawyer. If in double ask advice from a software lawyer to be sure.
