Method Detail

getIV

public byte[] getIV()

Return a copy of the current IV value.

Specified by:

getIV in interface ParametersWithIV<T extends GeneralParameters>

Returns:

the current IV.

withIV

public T withIV(java.security.SecureRandom random)

Return an implementation of our parameterized type with an IV constructed from the passed in SecureRandom.

Specified by:

withIV in interface ParametersWithIV<T extends GeneralParameters>

Parameters:

random - the SecureRandom to use as the source of IV data.

Returns:

a new instance of our parameterized type with a new IV.

withIV

public T withIV(byte[] iv)

Return an implementation of our parameterized type containing the passed in IV.

Specified by:

withIV in interface ParametersWithIV<T extends GeneralParameters>

Parameters:

iv - the bytes making up the iv, or nonce, to use.

Returns:

a new instance of our parameterized type with a new IV.
