Constructor Detail

Builder

public Builder(String algorithmName,
               int keySizeInBits)

Basic builder.

Parameters:

algorithmName - the algorithm name for the secret key we use for wrapping.

keySizeInBits - the size of the wrapping key we want to produce in bits.

Builder

public Builder(String algorithmName,
               int keySizeInBits,
               byte[] otherInfo)

Basic builder.

Parameters:

algorithmName - the algorithm name for the secret key we use for wrapping.

keySizeInBits - the size of the wrapping key we want to produce in bits.

otherInfo - the otherInfo/IV encoding to be applied to the KDF.

Method Detail

withParameterSpec

public KTSParameterSpec.Builder withParameterSpec(AlgorithmParameterSpec parameterSpec)

Set the algorithm parameter spec to be used with the wrapper.

Parameters:

parameterSpec - the algorithm parameter spec to be used in wrapping/unwrapping.

Returns:

the current Builder instance.

withKdfAlgorithm

public KTSParameterSpec.Builder withKdfAlgorithm(AlgorithmIdentifier kdfAlgorithm)

Set the KDF algorithm and digest algorithm for wrap key generation.

Parameters:

kdfAlgorithm - the KDF algorithm to apply.

Returns:

the current Builder instance.

build

public KTSParameterSpec build()

Build the new parameter spec.

Returns:

a new parameter spec configured according to the builder state.
