Cryptography

DCPcrypt is an open source library of cryptographic components (encryption algorithms and hash algorithms) for Borland Delphi and Kylix (it also works under some versions of C++ Builder). The idea behind DCPcrypt is that it should be possible to "drop in" any algorithm implementation to replace another with minimum or no code changes. To aid in this goal all cryptographic components are descended from one of several base classes, TDCP_cipher for encryption algorithms and TDCP_hash for message digest algorithms.

LockBox is a cross-platform toolkit for data encryption. It contains routines & components for use with Borland Delphi, C++Builder, & Kylix. It provides support for Blowfish, RSA, MD5, SHA-1, DES, triple-DES, Rijndael, & digital signing of messages.
