I've read in multiple places that the format of hashed/crypted/salted data should look something like so: $magic_number$ + salt + data
It looks like the magic number portion is specific to the type of algorithm used... ie: MD5 = $1$ Blowfish = $2$ Apache = $arp1$ Can someone point me to the RFC or some documentation on this ? I've noticed that PHP versions of crypt methods prepend this automatically, while in Perl, neither the Crypt or Digest modules implement this. Thanks !
