PBKDF2-HMAC-SHA-512 test vectors
cryptography, pbkdf2
Solution
I was able to verify all results against one I created
With another run to verify my own results, I verified P = "password" S = "salt" c = 4096 dkLen = 64 with a BouncyCastle implementation that was copy/pasted from SO
Thank you so much for posting test vectors. I hope more people will verify
Problem
I have not been able to find published test vectors for PBKDF2-HMAC-SHA-512. I've built a function that (finally!) reproduces the 7 HMAC-SHA-512 test vectors in RFC 4231, and the 32-byte test vectors for PBKDF2-HMAC-SHA-256 found in this thread. Here is what it generates for PBKDF2-HMAC-SHA-512. Can anyone help me verify this output? Thanks, Fred ``` Input: P = "password" S = "salt" c = 1 dkLen = 64 Output: DK = 86 7f 70 cf 1a de 02 cf f3 75 25 99 a3 a5 3d c4 af 34 c7 a6 69 81 5a e5 d5 13 55 4e 1c 8c f2 52 c0 2d 47 0a 28 5a 05 01 ba d9 99 bf e9 43 c0 8f 05 02 35 d7 d6 8b 1d a5 5e 63 f7 3b 60 a5 7f ce Input: P = "password" S = "salt" c = 2 dkLen = 64 Output: DK = e1 d9 c1 6a a6 81 70 8a 45 f5 c7 c4 e2 15 ce b6 6e 01 1a 2e 9f 00 40 71 3f 18 ae fd b8 66 d5 3c f7 6c ab 28 68 a3 9b 9f 78 40 ed ce 4f ef 5a 82 be 67 33 5c 77 a6 06 8e 04 11 27 54 f2 7c cf 4e Input: P = "password" S = "salt" c = 4096 dkLen = 64 Output: DK = d1 97 b1 b3 3d b0 14 3e 01 8b 12 f3 d1 d1 47 9e 6c de bd cc 97 c5 c0 f8 7f 69 02 e0 72 f4 57 b5 14 3f 30 60 26 41 b3 d5 5c d3 35 98 8c b3 6b 84 37 60 60 ec d5 32 e0 39 b7 42 a2 39 43 4a f2 d5 Input: P = "passwordPASSWORDpassword" S = "saltSALTsaltSALTsaltSALTsaltSALTsalt" c = 4096 dkLen = 64 Output: DK = 8c 05 11 f4 c6 e5 97 c6 ac 63 15 d8 f0 36 2e 22 5f 3c 50 14 95 ba 23 b8 68 c0 05 17 4d c4 ee 71 11 5b 59 f9 e6 0c d9 53 2f a3 3e 0f 75 ae fe 30 22 5c 58 3a 18 6c d8 2b d4 da ea 97 24 a3 d3 b8 ```
