krypto

• Golang implementation of cryptographic algorithms designed in Republic of Korea

• It is intended for compatibility with the crypto package.

• krypto does not required any other C/C++ compiler to use SIMD :)

  • But, may have not been optimized in compiler level.

LICNESE

Supported

• A : Not tested.

• ^ : Deprecated algorithm.

• Block cipher

SIMD Support

• It was based on the below.

  Algorithm	x86 SIMD Supports	Reference
  LEA	SSE2 AVX2*	KISA
  LSH-256	SSE2 SSSE3 AVX2**	KISA
  LSH-512	SSE2 SSSE3 AVX2	KISA

  • *: LEA AVX2 was Disabled in default.

    • SSSE3 is more faster then AVX2 in benchmarks. It seems like a different algorithm is needed.

    • you can enable LEA AVX2 manually by build from krypto_lea_avx2 tags.

      $ go build -tags=krypto_lea_avx2 .

  • **: LSH-256 AVX2 with Disabled in default.

    • SSSE3 is more faster then AVX2 in benchmarks. It seems like a different algorithm is needed.

    • but you can enable LSH-256 AVX2 manually by build from krypto_lsh256_avx2 tags.

      $ go build -tags=krypto_lsh256_avx2 .

Usage

Todo

TODO

• Optimized SIMD

• ARMv8 NEON supports

  • mmcloughlin/avo: Generate x86 Assembly with Go does not support ARM.

• Supoorts Post-Quantum Cryptography
