Given a Hash/pseudorandom function, get the PBKDF

module H : Digestif.S

val pbkdf1 : 
  password:string ->
  salt:string ->
  count:int ->
  dk_len:int ->
  string

pbkdf1 password salt count dk_len is dk, the derived key of dk_len octets. The salt must be eight octets, count the iteration count.

raises Invalid_argument
when either salt is not eight octets long or either count or dk_len are not valid.

val pbkdf2 : 
  password:string ->
  salt:string ->
  count:int ->
  dk_len:int32 ->
  string

pbkdf2 password salt count dk_len is dk, the derived key of dk_len octets.
