Interface OutputSigner<T extends Parameters>

Type Parameters:

T - the parameters type for the signer.

All Known Subinterfaces:

OutputSignerUsingSecureRandom<T>, OutputSignerWithMessageRecovery<T>

All Known Implementing Classes:

FipsOutputSigner, FipsOutputSignerUsingSecureRandom

public interface OutputSigner<T extends Parameters>

Base interface for an output signer.

Method Summary

Modifier and Type	Method and Description
T	getParameters() Return the parameters for this output signer.
byte[]	getSignature() Return the signature calculated on what has been written to the calculator's output stream.
int	getSignature(byte[] output, int off) Output the signature value for what has been written to the signer's output stream.
UpdateOutputStream	getSigningStream() Returns a stream that will accept data for the purpose of calculating a signature.

Method Detail

getParameters

T getParameters()

Return the parameters for this output signer.

Returns:

the signer's parameters.

getSigningStream

UpdateOutputStream getSigningStream()

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.

Returns:

an UpdateOutputStream

getSignature

byte[] getSignature()
             throws PlainInputProcessingException

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

Returns:

a signature.

Throws:

PlainInputProcessingException - if the input provided cannot be processed.

getSignature

int getSignature(byte[] output,
                 int off)
          throws PlainInputProcessingException

Output the signature value for what has been written to the signer's output stream.

Parameters:

output - output array to write the signature to.

off - offset to start writing the signature at.

Returns:

the number of bytes output.

Throws:

PlainInputProcessingException - if the input provided cannot be processed.
