1.  Introduction

The PKCS #5 [RFC2898] (Kaliski, B., “PKCS #5: Password-Based Cryptography Specification Version 2.0,” September 2000.) Password Based Key Derivation Function 2 (PBKDF2) is used by several protocols to derive encryption keys from a password.

Test vectors for the algorithm were not included in the original specification, but are often useful for implementers.

2.  PBKDF2 test vectors for HMAC-SHA1

The SCRAM (Newman, C., Menon-Sen, A., Melnikov, A., and N. Williams, “Salted Challenge Response (SCRAM) SASL and GSS-API Mechanism,” February 2010.) [I‑D.ietf‑sasl‑scram] protocol uses PBKDF2 with HMAC (Krawczyk, H., Bellare, M., and R. Canetti, “HMAC: Keyed-Hashing for Message Authentication,” February 1997.) [RFC2104] and SHA-1 (National Institute of Standards and Technology, “Secure Hash Standard,” April 1995.) [FIPS.180‑1.1995].

  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

  Input:
    P = "password" (8 octets)
    S = "salt" (4 octets)
    c = 2
    dkLen = 20

  Output:
    DK = ea 6c 01 4d c7 2d 6f 8c cd 1e d9 2a ce 1d 41 f0 d8 de 89 57

  Input:
    P = "password" (8 octets)
    S = "salt" (4 octets)
    c = 4096
    dkLen = 20

  Output:
    DK = 4b 00 79 01 b7 65 48 9a be ad 49 d9 26 f7 21 d0 65 a4 29 c1

  Input:
    P = "password" (8 octets)
    S = "salt" (4 octets)
    c = 16777216
    dkLen = 20

  Output:
    DK = ee fe 3d 61 cd 4d a4 e4 e9 94 5b 3d 6b a2 15 8c 26 34 e9 84

3.  Acknowledgements

Barry Brachman and Love Hörnquist Åstrand confirmed the test vectors and pointed out a mistake in the salt octet length count.
