Method Detail

getInstance

public static final IPad getInstance(java.lang.String pad)

Returns an instance of a padding algorithm given its name.

Parameters:

pad - the case-insensitive name of the padding algorithm.

Returns:

an instance of the padding algorithm, operating with a given block size, or null if none found.

Throws:

java.lang.InternalError - if the implementation does not pass its self-test.

getNames

public static final java.util.Set getNames()

Returns a Set of names of padding algorithms supported by this Factory.

Returns:

a Set of padding algorithm names (Strings).
