Key Derivation Functions

PBKDF1

  PBKDF1($P, $S, $c, $dkLen, [$Hash])

  Input:
         P     password, an octet string
         S     salt, an eight-octet string
         c     iteration count, a positive integer
         dkLen intended length in octets of derived key, a positive integer,
               at most 16 for MD2 or MD5 and 20 for SHA-1
  Options:
         Hash  underlyting Digest::* instance
  Output:
         DK    derived key, a dkLen-octet string

PBKDF2

  PBKDF2($P, $S, $c, $dkLen, [$PRF])
  
  Input:
         P     password, an octet string
         S     salt, an octet string
         c     iteration count, a positive integer
         dkLen intended length in octets of the derived key, a positive integer,
               at most (2**32 -1) x hLen
  Output:
         DK    derived key, a dkLen-octet string
  Options:
          PRF  underlying pseudorandom function (hLen denotes the length in
               octets of the pseudorandom function output)
