A fast, highly optimized implementation of symmetric
(private-key) encryption/decryption algorithms: DES,
Triple DES (3DES), DESX, BLOWFISH, RIJNDAEL (AES -
Advanced Encryption Standard), GOST (USSR/Russian
Encryption Standard). It supports 5 modes of
operation: ECB (Electronic Codebook), CBC (Cipher
Block Chaining), CFB (Cipher Feedback), OFB (Output
Feedback), CTR (Counter mode). The library allows to
encrypt/decrypt files, memory blocks, strings, blobs,
streaming data. It is quick, flexible, easy to use. It
supports 2 interfaces: QuickCrypt API (the API can be
used as is, or it can be used to create wrappers for
languages that can use DLL or LIB), and C++ Interface
(C++ wrapper classes to QuickCrypt API). It allows
static/dynamic linking. It has no external
dependencies such as MFC DLLs, COM/DCOM or other
component. The help file has C, C++ and Visual Basic
(VB) examples showing how to add encrypting/decrypting
functionality to Windows applications quickly and
easily.
