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.
