public Interface ContentVerifier

Known Direct Implementers: org.bouncycastle.operator.bc.BcContentVerifierProviderBuilder.SigVerifier, org.bouncycastle.operator.jcajce.JcaContentVerifierProviderBuilder.SigVerifier, org.bouncycastle.operator.jcajce.JcaContentVerifierProviderBuilder.CompositeVerifier
Imports: java.io.OutputStream, org.bouncycastle.asn1.x509.AlgorithmIdentifier

General interface for an operator that is able to verify a signature based on data in a stream of output.

Method Summary

Modifier and Type	Method and Description
public AlgorithmIdentifier	Returns: algorithm oid and parameters. getAlgorithmIdentifier() Return the algorithm identifier describing the signature algorithm and parameters this verifier supports.
public OutputStream	Returns: an OutputStream getOutputStream() Returns a stream that will accept data for the purpose of calculating a signature for later verification.
public boolean	Returns: true if the signature verifies, false otherwise verify(byte[] expected value of the signature on the data. expected) Return true if the expected value of the signature matches the data passed into the stream.

public AlgorithmIdentifier getAlgorithmIdentifier()

Return the algorithm identifier describing the signature algorithm and parameters this verifier supports.

Returns:AlgorithmIdentifier: algorithm oid and parameters.

getOutputStream	back to summary
public OutputStream getOutputStream() Returns a stream that will accept data for the purpose of calculating a signature for later verification. Use org.bouncycastle.util.io.TeeOutputStream if you want to accumulate the data on the fly as well. Returns:OutputStream an OutputStream

getOutputStream

back to summary

public OutputStream getOutputStream()

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

Returns:OutputStream: an OutputStream

verify	back to summary
public boolean verify(byte[] expected) Return true if the expected value of the signature matches the data passed into the stream. Parameters expected:byte[] expected value of the signature on the data. Returns:boolean true if the signature verifies, false otherwise

verify

back to summary

public boolean verify(byte[] expected)

Return true if the expected value of the signature matches the data passed into the stream.

Parameters

expected:byte[]: expected value of the signature on the data.

Returns:boolean

true if the signature verifies, false otherwise
