Aaron Toponce demonstrates why he thinks that using sha256crypt or sha512crypt on current GNU/Linux operating systems is dangerous, and why he thinks that the developers of GLIBC should move to scrypt or Argon2, or at least bcrypt or PBKDF2. After going into a bit of analysis, he concludes that practically everything else should be avoided, especially md5crypt, sha256crypt, and sha512crypt and many others.

    The best bit of the article for me, as someone who's been accused of using a "carp" architecture (ARM) rather than the non-carp x86, was this bit:
    "Ulrich Drepper tried creating something [better than what already was there], and ended up creating something worse."

    ARM is a carp architecture? Something fishy about that accusation...

      It's a riscy claim to make.
