public BouncyCastleGpgSignatureVerifier()

Creates a new instance and registers the BouncyCastle security provider if needed.

Method Detail

getName

public String getName()

Description copied from interface: GpgSignatureVerifier

Retrieves the name of this verifier. This should be a short string identifying the engine that verified the signature, like "gpg" if GPG is used, or "bc" for a BouncyCastle implementation.

Specified by:

getName in interface GpgSignatureVerifier

Returns:

the name

verifySignature

@Nullable
public GpgSignatureVerifier.SignatureVerification verifySignature(@NonNull
                                                                            RevObject object,
                                                                            @NonNull

Description copied from interface: GpgSignatureVerifier

Verifies the signature on a signed commit or tag.

Specified by:

verifySignature in interface GpgSignatureVerifier

Parameters:

object - to verify

config - the GpgConfig to use

Returns:

a GpgSignatureVerifier.SignatureVerification describing the outcome of the verification, or null if the object was not signed

Throws:

IOException - if an error occurs getting a public key

verify

public GpgSignatureVerifier.SignatureVerification verify(byte[] data,
                                                         byte[] signatureData)
                                                  throws IOException

Description copied from interface: GpgSignatureVerifier

Verifies a given signature for given data.

Specified by:

verify in interface GpgSignatureVerifier

Parameters:

data - the signature is for

signatureData - the ASCII-armored signature

Returns:

a GpgSignatureVerifier.SignatureVerification describing the outcome

Throws:

IOException - if the signature cannot be parsed

clear

public void clear()

Description copied from interface: GpgSignatureVerifier

A GpgSignatureVerifier may cache public keys to speed up verifying signatures on multiple objects. This clears this cache, if any.

Specified by:

clear in interface GpgSignatureVerifier
