Internet-Draft PKCS #5 PBKDF2 Test Vectors August 2010 1. Introduction The Public-Key Cryptography Standards (PKCS) #5 [RFC2898] Password Based Key Derivation Function 2 (PBKDF2) is used by several protocols to derive encryption keys from a password. For example, SCRAM [RFC5802] uses PBKDF2 with HMAC [RFC2104] and SHA-1 [FIPS.180-1.1995]. Test vectors for the algorithm were not included in the original specification, but are often useful for implementers. This document addresses this shortcoming. 2. PBKDF2 HMAC-SHA1 Test Vectors Below the input strings are encoded in ASCII [RFC0020]. An "\0" means a literal ASCII NUL value (1 octet). 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) 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 (20 octets) Josefsson Expires February 6, 2011 [Page 3]
