* complate reset of the SHA-3 code. Affects mostly the code in sha3.go * fixes a bug which causes SHAKE implementation to crash * implementation of Read()/Write() avoid unnecessary buffering as much as possible * NOTE: at some point I've done separated implementation for SumXXX, functions, but after optimizing implementation of Read/Write/Sum, the gain wasn't that big Current speed on Initial speed on i7-8665U@1.90 BenchmarkPermutationFunction 1592787 736 ns/op 271.90 MB/s 0 B/op 0 allocs/op BenchmarkSha3Chunk_x01/SHA-3/224 98752 11630 ns/op 176.02 MB/s 0 B/op 0 allocs/op BenchmarkSha3Chunk_x01/SHA-3/256 92508 12447 ns/op 164.46 MB/s 0 B/op 0 allocs/op BenchmarkSha3Chunk_x01/SHA-3/384 76765 15206 ns/op 134.62 MB/s 0 B/op 0 allocs/op BenchmarkSha3Chunk_x01/SHA-3/512 54333 21932 ns/op 93.33 MB/s 0 B/op 0 allocs/op BenchmarkSha3Chunk_x16/SHA-3/224 10000 102161 ns/op 160.37 MB/s 0 B/op 0 allocs/op BenchmarkSha3Chunk_x16/SHA-3/256 10000 106531 ns/op 153.80 MB/s 0 B/op 0 allocs/op BenchmarkSha3Chunk_x16/SHA-3/384 8641 137272 ns/op 119.35 MB/s 0 B/op 0 allocs/op BenchmarkSha3Chunk_x16/SHA-3/512 6340 189124 ns/op 86.63 MB/s 0 B/op 0 allocs/op BenchmarkShake_x01/SHAKE-128 167062 7149 ns/op 188.83 MB/s 0 B/op 0 allocs/op BenchmarkShake_x01/SHAKE-256 151982 7748 ns/op 174.24 MB/s 0 B/op 0 allocs/op BenchmarkShake_x16/SHAKE-128 12963 87770 ns/op 186.67 MB/s 0 B/op 0 allocs/op BenchmarkShake_x16/SHAKE-256 10000 105554 ns/op 155.22 MB/s 0 B/op 0 allocs/op BenchmarkCShake/cSHAKE-128 109148 10940 ns/op 187.11 MB/s 0 B/op 0 allocs/op BenchmarkCShake/cSHAKE-256 90324 13211 ns/op 154.94 MB/s 0 B/op 0 allocs/op PASS

// Package sha3 implements the Keccak-p[1600, 24] permuation.
|
|
// The 1600 stands for width of the permutation - number of

|
|
// of rounds (iterations) of the permuation.
|
|
// Package implementds derivatives of the Keccak permuation,
|
|
// like SHA-3 fixed-output-length hash, SHAKE which is an
|
|
// extendable-output-functions (XOF) and cSHAKE - a XOF with
|
|
// domain separation.
