Ed25519PublicKey.fromBytes constructor
Factory method for creating an Ed25519PublicKey from a byte array. It checks the length and prefix of the provided keyBytes to ensure validity. If the keyBytes include a public key prefix, it removes it before creating the instance.
Implementation
factory Ed25519PublicKey.fromBytes(List<int> keyBytes) {
if (keyBytes.length ==
Ed25519KeysConst.pubKeyByteLen + Ed25519KeysConst.pubKeyPrefix.length) {
final prefix = keyBytes.sublist(0, Ed25519KeysConst.pubKeyPrefix.length);
if (BytesUtils.bytesEqual(prefix, Ed25519KeysConst.pubKeyPrefix) ||
BytesUtils.bytesEqual(prefix, Ed25519KeysConst.xrpPubKeyPrefix)) {
keyBytes = keyBytes.sublist(1);
}
}
return Ed25519PublicKey._(
EDDSAPublicKey(Curves.generatorED25519, keyBytes));
}
