Method Detail

getInstance

public static final IBlockCipher getInstance(java.lang.String name)

Returns an instance of a block cipher given its name.

Parameters:

name - the case-insensitive name of the symmetric-key block cipher algorithm.

Returns:

an instance of the designated cipher algorithm, or null if none is 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 symmetric key block cipher implementation names supported by this Factory.

Returns:

a Set of block cipher names (Strings).
