Class FipsOutputSignerUsingSecureRandom<T extends Parameters>

java.lang.Object

org.bouncycastle.crypto.fips.FipsOutputSigner<T>

org.bouncycastle.crypto.fips.FipsOutputSignerUsingSecureRandom<T>

Type Parameters:

T - The parameters class for this signer.

All Implemented Interfaces:

OperatorUsingSecureRandom<OutputSignerUsingSecureRandom<T>>, OutputSigner<T>, OutputSignerUsingSecureRandom<T>

public abstract class FipsOutputSignerUsingSecureRandom<T extends Parameters>
extends FipsOutputSigner<T>
implements OutputSignerUsingSecureRandom<T>

Base class for a FIPS signature generator that makes use of a SecureRandom as part of the signing process.

Method Summary

Methods

Modifier and Type	Method and Description
abstract T	getParameters() Return the parameters for this output signer.
abstract byte[]	getSignature() Return the signature calculated on what has been written to the calculator's output stream.
abstract UpdateOutputStream	getSigningStream() Returns a stream that will accept data for the purpose of calculating a signature.
abstract FipsOutputSignerUsingSecureRandom<T>	withSecureRandom(java.security.SecureRandom random) Return a variant of this signer using the passed in random as its source of randomness.

Method Detail

getParameters

public abstract T getParameters()

Description copied from interface: OutputSigner

Return the parameters for this output signer.

Specified by:

getParameters in interface OutputSigner<T extends Parameters>

Specified by:

getParameters in class FipsOutputSigner<T extends Parameters>

Returns:

the signer's parameters.

getSigningStream

public abstract UpdateOutputStream getSigningStream()

Description copied from interface: OutputSigner

Returns a stream that will accept data for the purpose of calculating a signature. Use org.bouncycastle.util.io.TeeOutputStream if you want to accumulate the data on the fly as well.

Specified by:

getSigningStream in interface OutputSigner<T extends Parameters>

Specified by:

getSigningStream in class FipsOutputSigner<T extends Parameters>

Returns:

an UpdateOutputStream

getSignature

public abstract byte[] getSignature()
                             throws PlainInputProcessingException

Description copied from interface: OutputSigner

Return the signature calculated on what has been written to the calculator's output stream.

Specified by:

getSignature in interface OutputSigner<T extends Parameters>

Specified by:

getSignature in class FipsOutputSigner<T extends Parameters>

Returns:

a signature.

Throws:

PlainInputProcessingException - if the input provided cannot be processed.

withSecureRandom

public abstract FipsOutputSignerUsingSecureRandom<T> withSecureRandom(java.security.SecureRandom random)

Description copied from interface: OutputSignerUsingSecureRandom

Return a variant of this signer using the passed in random as its source of randomness.

Specified by:

withSecureRandom in interface OperatorUsingSecureRandom<OutputSignerUsingSecureRandom<T extends Parameters>>

Specified by:

withSecureRandom in interface OutputSignerUsingSecureRandom<T extends Parameters>

Parameters:

random - the SecureRandom to use.

Returns:

a signer which will use random where random data is required.
