The Public-Key Cryptography Standards (PKCS) #5 [<a href="./rfc2898" title=""PKCS #5: Password-Based Cryptography Specification Version 2.0"">RFC2898</a>] Password-
Based Key Derivation Function 2 (PBKDF2) is used by several protocols
to derive encryption keys from a password.
For example, Salted Challenge Response Authentication Mechanism
(SCRAM) [<a href="./rfc5802" title=""Salted Challenge Response Authentication Mechanism (SCRAM) SASL and GSS-API Mechanisms"">RFC5802</a>] uses PBKDF2 with Hash-based Message Authentication
Code (HMAC) [<a href="./rfc2104" title=""HMAC: Keyed- Hashing for Message Authentication"">RFC2104</a>] and Secure Hash Algorithm (SHA-1)
[<a href="#ref-FIPS.180-1.1995">FIPS.180-1.1995</a>].
Test vectors for the algorithm were not included in the original
specification, but are often useful for implementers. This document
addresses the shortcoming.

The input strings below are encoded using ASCII [<a href="#ref-ANSI.X3-4.1986">ANSI.X3-4.1986</a>].
The sequence "\0" (without quotation marks) means a literal ASCII NUL
value (1 octet). "DK" refers to the Derived Key.
Input:
P = "password" (8 octets)
S = "salt" (4 octets)
c = 1
dkLen = 20
Output:
DK = 0c 60 c8 0f 96 1f 0e 71
f3 a9 b5 24 af 60 12 06
2f e0 37 a6 (20 octets)

Barry Brachman and Love Hornquist Astrand confirmed the test vectors
(using independent implementations) and pointed out a mistake in the
salt octet length count.
