Class SecretAuthentication

  • All Implemented Interfaces:
    Authentication
    final class SecretAuthentication
extends java.lang.Object
implements Authentication
    Authentication block that manages a single authentication key and its secret string value (password, passphrase). Unlike StringAuthentication, the string value is kept in an encrypted buffer and only decrypted when needed to reduce the potential of leaking the secret in a heap dump.

                 java.util.Map<java.lang.String,​java.lang.String> data)
        Description copied from interface: Authentication
        Fills the given authentication context with the data from this authentication callback. To do so, implementors have to call AuthenticationContext.put(String, Object).

        The key parameter supplied to this method acts merely as a hint for interactive callbacks that want to prompt the user for only that authentication data which is required. Implementations are free to ignore this parameter and put all the data they have into the authentication context at once.
        Specified by:
        fill in interface Authentication
        Parameters:
        context - The authentication context to populate, must not be null.
        key - The key denoting a specific piece of authentication data that is being requested for a network operation, may be null.
        data - Any (read-only) extra data in form of key value pairs that might be useful when getting the authentication data, may be null.

      • digest

        public void digest​(AuthenticationDigest digest)
        Description copied from interface: Authentication
        Updates the given digest with data from this authentication callback. To do so, implementors have to call the update() methods in AuthenticationDigest.
        Specified by:
        digest in interface Authentication
        Parameters:
        digest - The digest to update, must not be null.
