RFC 2898 specifies two password-based key derivation functions (PBKDF1 and PBKDF2), which are abstracted over a specific hash/pseudorandom function.

Sourcemodule Make (H : Digestif.S) : S

Given a Hash/pseudorandom function, get the PBKDF

val pbkdf1 : 
  hash:Digestif.hash' ->
  password:string ->
  salt:string ->
  count:int ->
  dk_len:int ->
  string

convenience pbkdf1 hash password salt count dk_len where the hash has to be provided explicitly

val pbkdf2 : 
  prf:Digestif.hash' ->
  password:string ->
  salt:string ->
  count:int ->
  dk_len:int32 ->
  string

convenience pbkdf2 prf password salt count dk_len where the prf has to be provided explicitly
