public sealed class PrivatePasswordLeakVerification : IMessage<PrivatePasswordLeakVerification>, IEquatable<PrivatePasswordLeakVerification>, IDeepCloneable<PrivatePasswordLeakVerification>, IBufferMessage, IMessage
Reference documentation and code samples for the Google Cloud reCAPTCHA Enterprise v1 API class PrivatePasswordLeakVerification.
public RepeatedField<ByteString> EncryptedLeakMatchPrefixes { get; }
Output only. List of prefixes of the encrypted potential password leaks
that matched the given parameters. They must be compared with the
client-side decryption prefix of reencrypted_user_credentials_hash
public ByteString EncryptedUserCredentialsHash { get; set; }
Optional. Encrypted Scrypt hash of the canonicalized username+password. It
is re-encrypted by the server and returned through
reencrypted_user_credentials_hash.
Required. Exactly 26-bit prefix of the SHA-256 hash of the canonicalized
username. It is used to look up password leaks associated with that hash
prefix.
public ByteString ReencryptedUserCredentialsHash { get; set; }
Output only. Corresponds to the re-encryption of the
encrypted_user_credentials_hash field. It is used to match potential
password leaks within encrypted_leak_match_prefixes.
