encodeKey method

@override String encodeKey(List<int> pubKey)

Overrides the base class method to encode a public key as an ICON (ICX) address.

Implementation

@override
String encodeKey(List<int> pubKey) {
  /// Validate and transform the public key into a 32-byte hash.
  final IPublicKey pubKeyObj = AddrKeyValidator.validateAndGetSecp256k1Key(
    pubKey,
  );
  List<int> pubKeyHashBytes = QuickCrypto.sha3256Hash(
    pubKeyObj.uncompressed.sublist(1),
  );

  /// Truncate the hash to the required ICON address length.
  pubKeyHashBytes = pubKeyHashBytes.sublist(
    pubKeyHashBytes.length - IcxAddrConst.keyHashByteLen,
  );

  /// Add the ICON address prefix to the hash.
  return AddrKeyValidator.getConfigArg(
        CoinsConf.icon.params.addrPrefix,
        "addrPrefix",
      ) +
      BytesUtils.toHexString(pubKeyHashBytes);
}
