Bouncycastle GOST 34.311 hash differ from test examples differ

Question

could you, please, help with bouncycastle for hash function GOST 34.311. Somehow results are diffferent from test vector. Wiki says: "GOST("The quick brown fox jumps over the lazy dog") = 77b7fa410c9ac58a25f49bca7d0468c9296529315eaca76bd1a10f376d1f4294"

when using Digest Gost 34.11:

var testString = "The quick brown fox jumps over the lazy dog";
var result = (new GOST3411.Digest()).digest(testString.getBytes());
var resHex2 = new BigInteger(1, result).toString(16);
assertEquals("77b7fa410c9ac58a25f49bca7d0468c9296529315eaca76bd1a10f376d1f4294", resHex2.toUpperCase());

got:

org.opentest4j.AssertionFailedError: 
Expected :77b7fa410c9ac58a25f49bca7d0468c9296529315eaca76bd1a10f376d1f4294

with 2012 version:

var testString = "The quick brown fox jumps over the lazy dog";
var result = (new GOST3411.Digest2012_256()).digest(testString.getBytes());
var resHex2 = new BigInteger(1, result).toString(16);
assertEquals("77b7fa410c9ac58a25f49bca7d0468c9296529315eaca76bd1a10f376d1f4294", resHex2.toUpperCase());

got :

AssertionFailedError:

Actual   :3E7DEA7F2384B6C5A3D0E24AAA29C05E89DDD762145030EC22C71A6DB8B2C1F4

Does BouncyCastle support origin GOST 34.311 - 95? What is correct way to calculate it?

Answer 1

BC is using the GOST R 34.11-2012 (streebog) version of the standard

$ rhash -G -m "The quick brown fox jumps over the lazy dog"
3e7dea7f2384b6c5a3d0e24aaa29c05e89ddd762145030ec22c71a6db8b2c1f4  (message)

The wikipedia samples are for the deprecated GOST R 34.11-94 version

$ rhash --gost94 -m "The quick brown fox jumps over the lazy dog"
77b7fa410c9ac58a25f49bca7d0468c9296529315eaca76bd1a10f376d1f4294  (message)

If you actually want the old one, you should probably ask for plain GOST3411Digest instead of GOST3411.Digest2012_256 which is the new one.
