SMHasher3 is a test suite for evaluating non-cryptographic hash functions. It focuses on things like output distribution and collisions, with some perf tests. Based on the SMHasher fork maintained by Reini Urban (https://github.com/rurban/smhasher).

Integrity Check - Vinari Software is a Linux application written in Vala and GTK, designed to get the verification sum of a file (MD5, SHA1, SHA256, SHA512) and compare to the sum of verification provided by the file creator.

sha3sum - compute and check sha3xxx message digest. The command is similar to the GNU commands shaXXXsum. It use and wrap the RustCrypto/hashes lib.
