SumChecker

SumChecker is simple utility to calculate and check MD5, SHA1, SHA256 and SHA512 file hashes. The MD5 Message-Digest Algorithm is a widely used cryptographic hash function with a 128-bit (16-byte) hash value.

In cryptography, SHA-1 is a cryptographic hash function designed by the National Security Agency and published by the NIST as a U.S. Federal Information Processing Standard. SHA stands for Secure Hash Algorithm.
