Constructor Detail

PGPOnePassSignature

public PGPOnePassSignature(BCPGInputStream pIn)
                    throws java.io.IOException,
                           PGPException

Throws:

java.io.IOException

PGPException

Method Detail

init

public void init(PGPContentVerifierBuilderProvider verifierBuilderProvider,
                 PGPPublicKey pubKey)
          throws PGPException

Initialise the signature object for verification.

Parameters:

verifierBuilderProvider - provider for a content verifier builder for the signature type of interest.

pubKey - the public key to use for verification

Throws:

PGPException - if there's an issue with creating the verifier.

update

public void update(byte b)

update

public void update(byte[] bytes)

update

public void update(byte[] bytes,
                   int off,
                   int length)

verify

public boolean verify(PGPSignature pgpSig)
               throws PGPException

Verify the calculated signature against the passed in PGPSignature.

Parameters:

pgpSig -

Returns:

boolean

Throws:

PGPException

getKeyID

public long getKeyID()

getSignatureType

public int getSignatureType()

getHashAlgorithm

public int getHashAlgorithm()

getKeyAlgorithm

public int getKeyAlgorithm()

isContaining

public boolean isContaining()

Return true, if the signature is contains any signatures that follow. An bracketing OPS is followed by additional OPS packets and is calculated over all the data between itself and its corresponding signature (it is an attestation for contained signatures).

Returns:

true if containing, false otherwise

getEncoded

public byte[] getEncoded()
                  throws java.io.IOException

Throws:

java.io.IOException

encode

public void encode(java.io.OutputStream outStream)
            throws java.io.IOException

Throws:

java.io.IOException
