However the hash is good for many use cases as compared to the moth-eaten MD5 and even SHA1. The users section needs to have more entries. The Gluster project has been looking at bit rot detection which requires computing fast cryptographic hashes for files/fragments of files. BLAKE2 is ideal for the purpose and I submitted this bugzilla entry a while back. SHA256 is just too slow for that task. While Intel’s optimized SHA256 code is fast, BLAKE2-256 is a lot faster.
