the class SignatureAlgorithm method getDefaultSet.

/**
 * Get the available signature algorithms.
 *
 * @param keyPairAlgorithm The key pair algorithm to get the signature algorithms for.
 * @param defaultHint The default to return (may be {@code null}). If this algorithm is contained in the default
 *        set, it is also set as the default.
 * @param expertMode Whether only standard algorithms are considered ({@code false}) or all algorithms available on
 *        the current platform ({@code true}).
 * @return The available signature algorithms
