	Hash ActiveX Objects Version 1.3 
	 
	
	This is a collection of fifteen ActiveX objects that implement CRC-32 and Adler-32 checksum algorithms, seven cryptographic hash (also known as message digest) algorithms, and four algorithms for calculating Hash-based Message Authentication Codes (HMAC). The seven message-digest algorithms are: MD4 and MD5 developed by RSA Data Security, Inc., SHA-1 developed by the National Institute of Standards and Technology (NIST) and by the National Security Agency (NSA), RIPEMD-128, RIPEMD-160, RIPEMD-256, and RIPEMD-320 developed by Hans Dobbertin, Antoon Bosselaers, and Bart Preneel. HMAC algorithms are: HMAC-MD5, HMAC-SHA1, HMAC-RIPEMD128, and HMAC-RIPEMD160 based, respectively, on MD5, SHA-1, RIPEMD-128, and RIPEMD-160. 
Product features: 
- Unified interface to the most popular checksum, cryptographic hash, and HMAC algorithms.
 
- Includes implementation of RIPEMD family of algorithms, which are not available from the standard CryptoAPI providers.
 
- Optimized in assembly language for maximum performance on sixth generation x86 processors.
 
- Accessible from a wide range of programming languages and development environments.
 
- Designed for optimal performance in both single-threaded and multi-threaded environment.
