Method Detail

getMACSizeInBits

public int getMACSizeInBits()

Description copied from interface: AuthenticationParameters

Return the size of the MAC these parameters are for.

Specified by:

getMACSizeInBits in interface AuthenticationParameters

Returns:

the MAC size in bits.

getIV

public byte[] getIV()

Description copied from interface: ParametersWithIV

Return the initialization vector associated with this parameter set.

Specified by:

getIV in interface ParametersWithIV

Returns:

the IV for these parameters.

withIV

public FipsAES.AuthParameters withIV(byte[] iv)

Description copied from interface: ParametersWithIV

Create a new parameter set with a different IV.

Specified by:

withIV in interface ParametersWithIV

Parameters:

iv - the IV to use.

Returns:

a copy of the current parameter set with the new IV.

withIV

public FipsAES.AuthParameters withIV(java.security.SecureRandom random)

Description copied from interface: ParametersWithIV

Create a new parameter set with a different IV based on the output of the passed in random.

Specified by:

withIV in interface ParametersWithIV

Parameters:

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

Returns:

a copy of the current parameter set with the new IV.

withIV

public FipsAES.AuthParameters withIV(java.security.SecureRandom random,
                                     int ivLen)

Description copied from interface: AuthenticationParametersWithIV

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

Specified by:

withIV in interface AuthenticationParametersWithIV

Parameters:

random - source of randomness for iv (nonce)

ivLen - length of the iv (nonce) in bytes to use with the algorithm.

withMACSize

public FipsAES.AuthParameters withMACSize(int macSizeInBits)

Return a new set of parameters specifying a specific mac size.

Specified by:

withMACSize in interface AuthenticationParameters

Parameters:

macSizeInBits - bit length of the MAC length.

Returns:

a new set of AuthParameters for the MAC size.
