** Description changed:

- Keystone uses sha512_crypt for password hashing. This is completely
- insufficient and provides limited protection (even with 10,000 rounds)
- against brute-forcing of the password hashes (especially with FPGAs
- and/or GPU processing).
+ 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 pdkfd_sha512 instead
  of sha512_crypt.
  
  This bug is marked as public security as bug #1543048 has already
