hash

Hashing utilities: standard cryptographic hashes, HMAC, CRC, MurmurHash3, xxHash, and file/stream helpers.

Features

• Standard hashes: MD5, SHA-1, SHA-256, SHA-512
• HMAC: HMAC-SHA256, HMAC-SHA512 with constant-time comparison
• CRC: CRC16-CCITT, CRC32 (IEEE), CRC64 (ISO), Adler-32, FNV-1a
• Non-cryptographic: MurmurHash3 (32-bit and 128-bit x64), xxHash64, xxHash32
• File and stream hashing helpers

Key functions

• MD5 / MD5Hex / MD5String, SHA1 / SHA1Hex, SHA256 / SHA256Hex, SHA512 / SHA512Hex
• HMACSHA256 / HMACSHA256Hex, HMACSHA512 / HMACSHA512Hex, HMACEqual
• CRC16 / CRC16Hex, CRC32 / CRC32Hex, CRC64 / CRC64Hex
• Adler32, FNV1a32, FNV1a64
• Murmur3_32 / Murmur3_32Hex, Murmur3_128 / Murmur3_128Hex
• XXHash64 / XXHash64Hex, XXHash32 / XXHash32Hex
• MD5File(path), SHA256File(path) -- hash file contents

Quick start

import "github.com/LingByte/ling-base/common/hash"

hash.MD5Hex([]byte("hello"))              // "5d41402abc4b2a76b9719d911017c592"
hash.SHA256Hex([]byte("hello"))
hash.HMACSHA256Hex([]byte("data"), key)
hash.Murmur3_32Hex([]byte("hello"), 0)
hash.XXHash64Hex([]byte("hello"), 0)
