    Funny. BLAKE2 (being faster than MD5 yet more secure) seems to disprove that absolute (and utterly incorrect) correlation.

    The takeaway message for us lowly non-security types was pretty simple, yet none of us got it: I'll be pretty happy when I can replace the md5sum command line tool with something faster that I can have a reasonable amount of confidence in.

    So, as I said, it may be a reimplementation of a sha3 finalist algorithm.
