go-solidity-sha3
Generate Solidity SHA3 (Keccak256) hashes in Go.
This package is the Go equivalent of require('ethers').utils.solidityKeccak256 NPM module.
Install
go get github.com/Manifold-MEV/go-solidity-sha3

Getting started
Simple example:
package main
import (
"encoding/hex"
"fmt"
"github.com/Manifold-MEV/go-solidity-sha3"
)
func main() {
hash := solsha3.SoliditySHA3(
// types
[]string{"address", "uint256"},
// values
[]interface{}{
"0x935F7770265D0797B621c49A5215849c333Cc3ce",
"100000000000000000",
},
)
fmt.Println(hex.EncodeToString(hash))
}
Output:
0a3844b522d9e3a837ae56d4c57d668feb26325834bf4ba49e153d84ed7ad53d
More complex example:
package main
import (
"encoding/hex"
"fmt"
"github.com/Manifold-MEV/go-solidity-sha3"
)
func main() {
types := []string{"address", "bytes1", "uint8[]", "bytes32", "uint256", "address[]", "uint32"}
values := []interface{}{
"0x935F7770265D0797B621c49A5215849c333Cc3ce",
"0xa",
[]uint8{128, 255},
"0x4e03657aea45a94fc7d47ba826c8d667c0d1e6e33a64a036ec44f58fa12d6c45",
"100000000000000000",
[]string{
"0x13D94859b23AF5F610aEfC2Ae5254D4D7E3F191a",
"0x473029549e9d898142a169d7234c59068EDcBB33",
},
123456789,
}
hash := solsha3.SoliditySHA3(types, values)
fmt.Println(hex.EncodeToString(hash))
}
Output:

var ( MaxBig256 = new(big.Int).Set(tt256m1) MaxBig63 = new(big.Int).Sub(tt63, big.NewInt(1)) )
Various big integer limit values.
Functions ¶
func ConcatByteSlices ¶
ConcatByteSlices concat byte slices
func LeftPadBytes ¶
LeftPadBytes zero-pads slice to the left up to length l.
func PaddedBigBytes ¶
PaddedBigBytes encodes a big integer as a big-endian byte slice. The length of the slice is at least n bytes.
func ReadBits ¶
ReadBits encodes the absolute value of bigint as big-endian bytes. Callers must ensure that buf has enough space. If buf is too short the result will be incomplete.
func RightPadBytes ¶
RightPadBytes zero-pads slice to the right up to length l.
func SoliditySHA3WithPrefix ¶
SoliditySHA3WithPrefix solidity sha3 with prefix
Types ¶
This section is empty.
