sha256

Calculates the SHA-256 hash of a byte array or hex value

sha256

Calculates the SHA-256 hash of a byte array or hex value.

Import

import "github.com/ChefBingbong/viem-go/utils/hash"

Usage

import "github.com/ChefBingbong/viem-go/utils/hash"

// Hash bytes
h := hash.Sha256([]byte("hello world"))
// "0xb94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9"

// Hash hex string
h = hash.Sha256("0x68656c6c6f20776f726c64")
// "0xb94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9"

// Hash string (UTF-8)
h = hash.Sha256("hello world")
// "0xb94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9"

// Get raw bytes
bytes := hash.Sha256Bytes([]byte("hello world"))
// []byte{...}

Returns

Type: string for Sha256, []byte for Sha256Bytes

The hashed value. Sha256 returns a hex string with 0x prefix, Sha256Bytes returns raw bytes.

Parameters

value (required)

Type: any (supports []byte or string)

The hex value or byte array to hash. If a string is provided without 0x prefix, it's treated as UTF-8.

// Hash bytes
hash := hash.Sha256([]byte("hello"))

// Hash hex string
hash = hash.Sha256("0x68656c6c6f")

// Hash UTF-8 string
hash = hash.Sha256("hello")

Functions

Sha256

Computes SHA-256 hash and returns a hex string:

hash := hash.Sha256([]byte("hello"))
// "0x2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824"

Sha256Bytes

Computes SHA-256 hash and returns raw bytes:

bytes := hash.Sha256Bytes([]byte("hello"))
// []byte{0x2c, 0xf2, 0x4d, ...}
