go-multihash
multihash implementation in Go
Table of Contents
Install
go-multihash is a standard Go module which can be installed with:
go get github.com/multiformats/go-multihash
Usage
Example
This example takes a standard hex-encoded data and uses EncodeName to calculate the SHA1 multihash value for the buffer.
The resulting hex-encoded data corresponds to: <hash function code><digest size><hash function output>, which could be re-parsed
with Multihash.FromHexString().
package main
import (
"encoding/hex"
"fmt"
"github.com/multiformats/go-multihash"
)
func main() {
// ignores errors for simplicity.
// don't do that at home.
// Decode a SHA1 hash to a binary buffer
buf, _ := hex.DecodeString("0beec7b5ea3f0fdbc95d0dd47f3c5bc275da8a33")
// Create a new multihash with it.
mHashBuf, _ := multihash.EncodeName(buf, "sha1")
// Print the multihash as hex string
fmt.Printf("hex: %s\n", hex.EncodeToString(mHashBuf))
// Parse the binary multihash to a DecodedMultihash
mHash, _ := multihash.Decode(mHashBuf)
// Convert the sha1 value to hex string
sha1hex := hex.EncodeToString(mHash.Digest)
// Print all the information in the multihash
fmt.Printf("obj: %v 0x%x %d %s\n", mHash.Name, mHash.Code, mHash.Length, sha1hex)
}
To run, copy to example/foo.go and:
> cd example/
> go build
> ./example
hex: 11140beec7b5ea3f0fdbc95d0dd47f3c5bc275da8a33
obj: sha1 0x11 20 0beec7b5ea3f0fdbc95d0dd47f3c5bc275da8a33
