SimpleHasher

Simple Hasher is a Hashing utility for verifying integrity of files using a wide range of supported algorithms: CRC32, ED2K, MD4, MD5, RIPEMD160, SHA1, SHA256, SHA384, SHA512 and WHIRLPOOL512. All processed files are logged and ready for export to a number of different verification file formats Like SFV, MD5SUM, SHA1SUM. Multiple hash types can be generated simultaneously per file. Handy hash and file comparison functions, such as comparing calculated hashes will make this task as simple as A-B-C.
