encodeKey method
Blockchain address encoder for Ada Shelley addresses. This encoder is used to create addresses based on public and private key pairs.
Implementation
@override
String encodeKey(List<int> pubKey, [Map<String, dynamic> kwargs = const {}]) {
/// Determine the network tag, defaulting to mainnet if not specified.
final netTag = kwargs["net_tag"] ?? ADANetwork.mainnet;
/// Check if the provided network tag is a valid enum value.
if (netTag is! ADANetwork) {
throw const AddressConverterException(
'Address type is not an enumerative of ADANetwork');
}
/// Validate and retrieve public keys.
final pubKeyObj = AddrKeyValidator.validateAndGetEd25519Key(pubKey);
// Compute key hashes for public spending and public delegation keys.
final pubKeyHash =
AdaShelleyAddrUtils.keyHash(pubKeyObj.compressed.sublist(1));
return AdaShelleyAddrUtils.encode(
credential:
AdaStakeCredential(hash: pubKeyHash, type: AdaStakeCredType.key),
netTag: netTag,
hrp: AdaShelleyAddrConst.networkTagToAddrHrp[netTag]!,
type: ADAAddressType.enterprise);
