Marc Tiehuis	8938429ea1	Add Hmac function (#890)	2018-04-04 10:31:10 -04:00
Marc Tiehuis	7a3fd89d25	Add Sha3 hashing functions ... These are on the slower side and could be improved. No performance optimizations yet have been done. ``` Cpu: Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz ``` -- Sha3-256 ``` Zig --release-fast 93 Mb/s Zig --release-safe 99 Mb/s Zig 4 Mb/s ``` -- Sha3-512 ``` Zig --release-fast 49 Mb/s Zig --release-safe 54 Mb/s Zig 2 Mb/s ``` Interestingly, release-safe is producing slightly better code than release-fast.	2018-01-17 21:19:45 +13:00
Marc Tiehuis	7af53d0826	Fix crypto exports	2018-01-17 21:19:45 +13:00
Marc Tiehuis	fa7b33549e	Change crypto functions to fill a buffer ... - Rename blake2x -> blake2 - Fix blake2s truncated tests	2018-01-17 00:17:48 +13:00
Marc Tiehuis	4cf86b4a94	Add Blake2X hash functions ... The truncated output variants currently are dependent on a more complete bigint implementation in the compiler.	2018-01-15 23:14:13 +13:00
Marc Tiehuis	2659ac01be	Add Sha2 functions ... We take the fastest time measurement taken across multiple runs. Tested across multiple compiler flags and the best chosen. ``` Cpu: Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz Gcc: 7.2.1 20171224 Clang: 5.0.1 Zig: 0.1.1.304f6f1d ``` See https://www.nayuki.io/page/fast-sha2-hashes-in-x86-assembly. ``` Gcc -O2 219 Mb/s Clang -O2 213 Mb/s Zig --release-fast 284 Mb/s Zig --release-safe 211 Mb/s Zig 6 Mb/s ``` ``` Gcc -O2 350 Mb/s Clang -O2 354 Mb/s Zig --release-fast 426 Mb/s Zig --release-safe 300 Mb/s Zig 11 Mb/s ```	2018-01-13 22:37:47 +13:00
Marc Tiehuis	51fdbf7f8c	Add Md5 and Sha1 hash functions ... Some performance comparisons to C. We take the fastest time measurement taken across multiple runs. The block hashing functions use the same md5/sha1 methods. ``` Cpu: Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz Gcc: 7.2.1 20171224 Clang: 5.0.1 Zig: 0.1.1.304f6f1d ``` See https://www.nayuki.io/page/fast-md5-hash-implementation-in-x86-assembly: ``` gcc -O2 661 Mb/s clang -O2 490 Mb/s zig --release-fast and zig --release-safe 570 Mb/s zig 50 Mb/s ``` See https://www.nayuki.io/page/fast-sha1-hash-implementation-in-x86-assembly: ``` gcc -O2 588 Mb/s clang -O2 563 Mb/s zig --release-fast and zig --release-safe 610 Mb/s zig 21 Mb/s ``` In short, zig provides pretty useful tools for writing this sort of code. We are in the lead against clang (which uses the same LLVM backend) with us being slower only against md5 with GCC.	2018-01-13 14:40:21 +13:00
