About:

    Hash is a MacOSX application to generate and verify the
    hash, crc, or checksum of a file.

    By default, Hash runs in a "simple" mode that supports
    the following hashes:

        MD5
        SHA1
        SHA256
        SHA512
        RIPEMD 160
        BLAKE3

    In the full mode, the following hash functions are
    supported:

        MD5
        SHA1
        SHA1 DC (SHA1 with collision detection / protection)
        SHA2 (SHA224, SHA256, SHA384, SHA512)
        SHA3/SHAKE (128, 224, 256, 384, 512)
        RIPEMD (160, 320)
        KangarooTwelve / K12 (256, 384, 512)
        Whirlpool
        BLAKE (224, 256, 384, 512)
        BLAKE2 (BLAKE2S 256; BLAKE2B 256, 512)
        BLAKE3
        Skein (256-256, 512-256, 512-512, 1024-256, 1024-512)
        MD6 (256, 512)
        JH (224, 256, 384, 512)
        Groestl (224, 256, 384, 512)
        Tiger, Tiger2
        HAS-160
        Snefru (128, 256)
        LSH (224, 256, 384, 512)
