generateRSAkeyPair function

AsymmetricKeyPair<RSAPublicKey, RSAPrivateKey> generateRSAkeyPair({ int bitLength = 2048, })

Implementation

AsymmetricKeyPair<RSAPublicKey, RSAPrivateKey> generateRSAkeyPair(
    {int bitLength = 2048}) {
  SecureRandom secureRandom = exampleSecureRandom();
  // Create an RSA key generator and initialize it

  //final keyGen = KeyGenerator('RSA'); // Get using registry
  final keyGen = RSAKeyGenerator();

  keyGen.init(ParametersWithRandom(
      RSAKeyGeneratorParameters(BigInt.parse('65537'), bitLength, 64),
      secureRandom));

  // Use the generator

  final pair = keyGen.generateKeyPair();

  // Cast the generated key pair into the RSA key types

  final myPublic = pair.publicKey as RSAPublicKey;
  final myPrivate = pair.privateKey as RSAPrivateKey;

  return AsymmetricKeyPair<RSAPublicKey, RSAPrivateKey>(myPublic, myPrivate);
