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/miguelmota/go-solidity-sha3Documentation
Getting started
Simple example:
package main
import (
"encoding/hex"
"fmt"
"github.com/miguelmota/go-solidity-sha3"
)
func main() {
hash := solsha3.SoliditySHA3(
// types
[]string{"address", "uint256"},
// values
[]interface{}{
"0x935F7770265D0797B621c49A5215849c333Cc3ce",
"100000000000000000",
},
)
fmt.Println(hex.EncodeToString(hash))
}Output:

package main
import (

)
func main() {
types := []string{"address", "bytes1", "uint8[]", "bytes32", "uint256", "address[]", "uint32"}
values := []interface{}{
