Example

Here's an example on how to create an IPNS Record:

import (
	"crypto/rand"
	"time"

	"github.com/ipfs/boxo/ipns"
	"github.com/ipfs/boxo/path"
	ic "github.com/libp2p/go-libp2p/core/crypto"
)

func main() {
	// Create a private key to sign your IPNS record. Most of the time, you
	// will want to retrieve an already-existing key from Kubo, for example.
	sk, _, err := ic.GenerateEd25519Key(rand.Reader)
	if err != nil {
		panic(err)
	}

	// Define the path this record will point to.
	path, err := path.NewPath("/ipfs/bafkqac3jobxhgidsn5rww4yk")
	if err != nil {
		panic(err)
	}

	// Until when the record is valid.
	eol := time.Now().Add(time.Hour)

	// For how long should caches cache the record.
	ttl := time.Second * 20

	record, err := ipns.NewRecord(sk, path, 1, eol, ttl)
	if err != nil {
		panic(err)
	}

	// Now you have an IPNS Record.
}
