CryptoSys API Server Edition

The CryptoSys API package provides a developer's toolkit of fast, efficient symmetrical cryptographic functions in Visual Basic, VBA, VB.NET/VB2005/8, C/C++, C#, and ASP. You can incorporate it in your own apps and it can be called from VBA applications like Access, Excel and Word.

It provides four of the major block cipher algorithms, a stream cipher algorithm, key wrap, secure message digest hash algorithms, the HMAC message authentication algorithm, the CMAC algorithm, a data compression facility, a password-based key derivation function (PBKDF2), a secure random number generator and other utilities.

The CryptoSys API provides functions to carry out primitive cryptographic operations intended to be used as part of a security-related application. It is up to you the programmer to ensure that keys, passwords and other private data in your application are kept secret, and to ensure that appropriate security policies and procedures are followed by end users.

The block cipher algorithms in the CryptoSys API are: - The Advanced Encryption Standard (AES)  - The original Data Encryption Standard (DES)  - Its currently approved replacement, Triple DES (TDEA, 3DES)  - Bruce Schneier's Blowfish
