(Go) Generate an Ed25519 Key Pair
Demonstrates how to generate a new Ed25519 public/private key pair.
Note: This example requires Chilkat v9.5.0.83 or greater.
// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
eddsa := chilkat.NewEdDSA()
prng := chilkat.NewPrng()
privKey := chilkat.NewPrivateKey()
// Generates a new eddsa key and stores it in privKey.
success := eddsa.GenEd25519Key(prng,privKey)
if success == false {
fmt.Println(eddsa.LastErrorText())
eddsa.DisposeEdDSA()
prng.DisposePrng()
privKey.DisposePrivateKey()
return
}
// Examine the ed25519 key in JWK format;
jwk := privKey.GetJwk()
json := chilkat.NewJsonObject()
json.Load(*jwk)
json.SetEmitCompact(false)
fmt.Println(*json.Emit())
// Sample output:
// {
// "kty": "OKP",
// "crv": "Ed25519",
// "x": "SE2Kne5xt51z1eciMH2T2ftDQp96Gl6FhY6zSQujiP0",
// "d": "O-eRXewadF0sNyB0U9omcnt8Qg2ZmeK3WSXPYgqe570",
// "use": "sig"
// }
// In the above JWK, x is the public key, y is the private key.
// Both are 32 bytes and are base64-url encoded.
eddsa.DisposeEdDSA()
prng.DisposePrng()
privKey.DisposePrivateKey()
json.DisposeJsonObject()
