encryptData method
Encrypt a message which can only be decrypted using the associated RSAPrivateKey
Implementation
Uint8List encryptData(Uint8List message) {
final cipher = pointy.PKCS1Encoding(pointy.RSAEngine());
cipher.init(
true, pointy.PublicKeyParameter<pointy.RSAPublicKey>(_publicKey));
return cipher.process(message);
}
