Method Detail

createCryptoSuite

CryptoSuite createCryptoSuite(String suite)

Creates a crypto suite instance for the grammar implementing this interface.

Parameters:

suite - The suite name that defines the cryptographic parameters.

Returns:

A crypto suite instance based on the supplied suite name.

createKeyParam

KeyParam createKeyParam(String keyParam)

Creates a key parameter instance for the grammar implementing this interface.

Parameters:

keyParam - The textual representation of the key parameter field.

Returns:

The parsed key parameter.

createKeyParamArray

KeyParam[] createKeyParamArray(int size)

Utility method to create a typed array of KeyParameters.

Parameters:

size - The size of the array to create.

Returns:

KeyParam array of the specified size.

createSessionParam

SessionParam createSessionParam(String sessionParam)

Creates a session parameter instance for the grammar implementing this interface.

Parameters:

sessionParam - The textual representation of the session parameter.

Returns:

The parsed session parameter.

createSessionParamArray

SessionParam[] createSessionParamArray(int size)

Utility method to create a typed array of SessionParams.

Parameters:

size - The size of the array to create.

Returns:

SessionParam array of the specified size.

createCryptoAttribute

CryptoAttribute createCryptoAttribute()

Creates an empty crypto attribute for the grammar implementing this interface.

Returns:

Empty crypto attribute to be filled by a parser.

setRandomGenerator

void setRandomGenerator(Random r)

Sets the random number generator to be used for generating the SDES keys.

Parameters:

r - The random number generator.
