Request for Comments: 2898 PKCS #5: Password-Based Cryptography Specification

Version 2.0

PBKDF2 (P, S, c, dkLen)

Options:

PRF underlying pseudorandom function (hLen denotes the length in octets of the pseudorandom function output). PRF is pluggable.

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) * hLen

Output:

DK derived key, a dkLen-octet string
