Bug description:
  Keystone uses sha512_crypt for password hashing. This is insufficient
  and provides limited protection (even with 10,000 rounds) against
  brute-forcing of the password hashes (especially with FPGAs and/or GPU
  processing).

  The correct mechanism is to use bcrypt, scrypt, or pbkdf2_sha512
  instead of sha512_crypt.

  This bug is marked as public security as bug #1543048 has already
  highlighted this issue.
