This in an excerpt from previously sent patch set [PATCH 00/13] GOST cipher/MAC/hash algorithms support

This patch series concentrates on gosthash94 support. It adds gosthash94cp -- GOST R 34.11-94 variant using more popular S-Box and implements HMAC and PBKDF2 interfaes for GOST hashing algorithms.

References: - GOST R 34.11-94: RFC 5831 https://tools.ietf.org/html/rfc5831 - GOST 28147-89: RFC 5830 https://tools.ietf.org/html/rfc5830 - S-Boxes: RFC 4357 https://tools.ietf.org/html/rfc4357

Dmitry Eremin-Solenikov (5): Add GOST R 34.11 to nettle_hashes Start separating GOST 28147-89 from GOST R 34.11-94 Add support for GOSTHASH94CP: GOST R 34.11-94 hash with CryptoPro S-box Add HMAC functions for GOSTHASH94 and GOSTHASH94CP Add PBKDF2 support for gosthash94cp

New subject: [PATCH 2/5] Start separating GOST 28147-89 from GOST R 34.11-94

Hash function GOST R 34.11-94 (gosthash94) in its compression function uses Russian block cipher (GOST 28147-89, Magma). Start separating block cipher code from hash function code. For now there is no public interface for this cipher, it will be added later.

New subject: [PATCH 3/5] Add support for GOSTHASH94CP: GOST R 34.11-94 hash with CryptoPro S-box

Hash gosthash94 implements GOST R 34.11-94 standard using S-Box defined in the standard 'for testing purposes only'. RFC 4357 defines S-Box (CryptoPro one) for GOST R 34.11-94 hash function that is widely used in applications. Add separate hash function algorithm (gosthash94cp) implementing GOST R 34.11-94 hashing using that S-Box.

New subject: [PATCH 5/5] Add PBKDF2 support for gosthash94cp

Russian technical comitee working on standartization of cryptography algorithms has published the document describing usage of GOST R 34.11-94 hash function with PBKDF2 algorithm (http://tc26.ru/methods/containers_v1/Addition_to_PKCS5_v1_0.pdf). Add test vectors from that document and a special function implementing Nettle interface for PBKDF2 using gosthash94cp.

...

This in an excerpt from previously sent patch set [PATCH 00/13] GOST cipher/MAC/hash algorithms support

This patch series concentrates on gosthash94 support. It adds gosthash94cp -- GOST R 34.11-94 variant using more popular S-Box and implements HMAC and PBKDF2 interfaes for GOST hashing algorithms.

Any update on these patches? Review/comments/etc?
