Method Detail

withDigest

public FipsDH.AgreementParameters withDigest(FipsAlgorithm digestAlgorithm)

Add a digest algorithm to process the Z value with.

Parameters:

digestAlgorithm - digest algorithm to use.

Returns:

a new parameter set, including the digest algorithm

withPRF

public FipsDH.AgreementParameters withPRF(FipsKDF.PRF prfAlgorithm,
                                          byte[] salt)

Add a PRF algorithm and salt to process the Z value with (as in SP 800-56C)

Parameters:

prfAlgorithm - PRF represent the MAC/HMAC algorithm to use.

salt - the salt to use to initialise the PRF

Returns:

a new parameter set, including the digest algorithm

withKDF

public FipsDH.AgreementParameters withKDF(FipsKDF.AgreementKDFParametersBuilder kdfType,
                                          byte[] iv,
                                          int outputSize)

Add a KDF to process the Z value with. The outputSize parameter determines how many bytes will be generated.

Parameters:

kdfType - KDF algorithm type to use for parameter creation.

iv - the iv parameter for KDF initialization.

outputSize - the size of the output to be generated from the KDF.

Returns:

a new parameter set, the KDF definition.
