Correctness of Skein implementation #34

Closed verement closed 9 years ago

verement commented 9 years ago

Has the Skein implementation been verified?

The reason I ask is I can’t seem to reproduce the test vectors from the Skein paper:

C.1 Skein-256-256

Message data:
     FF

Result:
     A4 7B E7 1A 18 5B A0 AF 82 0B 3C E8 45 A3 D3 5A
     80 EC 64 F9 6A 0D 6A 36 E3 F5 36 36 24 D8 A0 91

In ghci:

Prelude Crypto.Hash Data.ByteString> hash $ pack [0xFF] :: Digest Skein256_256
0b98dcd198ea0e50a7a244c444e25c23da30c10fc9a1f270a6637f1f34e67ed2

Am I overlooking something?

Thanks.

skein is version 1.3 now; all the test vectors are differents now
