This package contains all of the components necessary to create, understand, and validate IPNS records. It does not publish or resolve those records. Kubo uses this package internally to manipulate records.

Usage

To create a new IPNS record:

import (
	"time"

	ipns "github.com/ipfs/go-ipns"
	crypto "github.com/libp2p/go-libp2p-crypto"
)

// Generate a private key to sign the IPNS record with. Most of the time, 
// however, you'll want to retrieve an already-existing key from IPFS using the
// go-ipfs/core/coreapi CoreAPI.KeyAPI() interface.
privateKey, publicKey, err := crypto.GenerateKeyPair(crypto.RSA, 2048)
if err != nil {
  panic(err)
}

// Create an IPNS record that expires in one hour and points to the IPFS address
// /ipfs/Qme1knMqwt1hKZbc1BmQFmnm9f36nyQGwXxPGVpVJ9rMK5
ipnsRecord, err := ipns.Create(privateKey, []byte("/ipfs/Qme1knMqwt1hKZbc1BmQFmnm9f36nyQGwXxPGVpVJ9rMK5"), 0, time.Now().Add(1*time.Hour))
if err != nil {
	panic(err)
}

Once you have the record, you’ll need to use IPFS to publish it.

There are several other major operations you can do with go-ipns. Check out the API docs or look at the tests in this repo for examples.
