KeyPair PublicKey to bytes about cryptography HOT 2 OPEN

// First generate KeyPair
KeyPair keyPair = await X25519().newKeyPair();

// To get the public key bytes you have to use SimplePublicKey
SimplePublicKey publicKey = await keyPair.extractPublicKey();
List<int> publicKeyBytes = publicKey.bytes; // now this works


// To extract the private key do the following:
// extract SimpleKeyPairData
SimpleKeyPairData simpleKeyPairData = await keyPair.extract();

// then you can extract the private key bytes
List<int> privateKeyBytes = await simpleKeyPairData.extractPrivateKeyBytes();
