Method Details

getInstance

public static IMac getInstance(String name)
Return an instance of a HMAC algorithm given the name of its underlying hash function, prefixed with the literal defined in Registry.HMAC_NAME_PREFIX.
Parameters:
name - the fully qualified name of the underlying algorithm: composed as the concatenation of a literal prefix (see Registry.HMAC_NAME_PREFIX) and the name of the underlying hash algorithm.
Returns:
an instance of the HMAC algorithm, or null if none can be constructed.

getNames

public static final Set<E> getNames()
Returns a Set of names of HMAC algorithms supported by this Factory.
Returns:
a Set of HMAC algorithm names (Strings).
