Constructor Details

OpenPGPComponentSignature

public OpenPGPComponentSignature(PGPSignature signature,
 OpenPGPCertificate.OpenPGPComponentKey issuer,
 OpenPGPCertificate.OpenPGPCertificateComponent target)

Component signature.

Parameters:

signature - signature

issuer - key that issued the signature. Is nullable (e.g. for 3rd party sigs where the certificate is not available).

target - signed certificate component

Method Details

getIssuerComponent

public OpenPGPCertificate.OpenPGPComponentKey getIssuerComponent()

Return the OpenPGPCertificate.OpenPGPComponentKey that issued this signature.

Returns:

issuer

getTargetComponent

public OpenPGPCertificate.OpenPGPCertificateComponent getTargetComponent()

Return the OpenPGPCertificate.OpenPGPCertificateComponent that this signature was calculated over.

Returns:

target

getTargetKeyComponent

public OpenPGPCertificate.OpenPGPComponentKey getTargetKeyComponent()

Return the OpenPGPCertificate.OpenPGPComponentKey that this signature is calculated over. Contrary to getTargetComponent(), which returns the actual target, this method returns the OpenPGPCertificate.OpenPGPComponentKey "closest" to the target. For a subkey-binding signature, this is the target subkey, while for an identity-binding signature (binding for a user-id or attribute) the return value is the OpenPGPCertificate.OpenPGPComponentKey which carries the identity.

Returns:

target key component of the signature

getKeyExpirationTime

public Date getKeyExpirationTime()

Return the key expiration time stored in the signature.

Returns:

key expiration time

verify

public void verify(OpenPGPImplementation implementation)
            throws PGPSignatureException

Verify this signature.

Parameters:

implementation - OpenPGP implementation

Throws:

PGPSignatureException - if the signature cannot be verified successfully

verify

public void verify(PGPContentVerifierBuilderProvider contentVerifierBuilderProvider,
 OpenPGPPolicy policy)
            throws PGPSignatureException

Verify this signature.

Parameters:

contentVerifierBuilderProvider - provider for verifiers

policy - algorithm policy

Throws:

PGPSignatureException - if the signature cannot be verified successfully

verifyKeySignature

protected void verifyKeySignature(OpenPGPCertificate.OpenPGPComponentKey issuer,
 OpenPGPCertificate.OpenPGPComponentKey target,
 PGPContentVerifierBuilderProvider contentVerifierBuilderProvider)
                           throws PGPSignatureException

Verify a signature of type PGPSignature.DIRECT_KEY, PGPSignature.KEY_REVOCATION, PGPSignature.SUBKEY_BINDING or PGPSignature.SUBKEY_REVOCATION.

Parameters:

issuer - issuing component key

target - targeted component key

contentVerifierBuilderProvider - provider for content verifier builders

Throws:

PGPSignatureException - if an exception happens during signature verification

verifyUserIdSignature

protected void verifyUserIdSignature(OpenPGPCertificate.OpenPGPComponentKey issuer,
 OpenPGPCertificate.OpenPGPUserId target,
 PGPContentVerifierBuilderProvider contentVerifierBuilderProvider)
                              throws PGPSignatureException

Verify a certification signature over an OpenPGPCertificate.OpenPGPUserId. The signature is of type PGPSignature.DEFAULT_CERTIFICATION, PGPSignature.NO_CERTIFICATION, PGPSignature.CASUAL_CERTIFICATION, PGPSignature.POSITIVE_CERTIFICATION or PGPSignature.CERTIFICATION_REVOCATION.

Parameters:

issuer - issuing component key

target - targeted userid

contentVerifierBuilderProvider - provider for content verifier builders

Throws:

PGPSignatureException - if an exception happens during signature verification

verifyUserAttributeSignature

protected void verifyUserAttributeSignature(OpenPGPCertificate.OpenPGPComponentKey issuer,
 OpenPGPCertificate.OpenPGPUserAttribute target,
 PGPContentVerifierBuilderProvider contentVerifierBuilderProvider)
                                     throws PGPSignatureException

Verify a certification signature over an OpenPGPCertificate.OpenPGPUserAttribute. The signature is of type PGPSignature.DEFAULT_CERTIFICATION, PGPSignature.NO_CERTIFICATION, PGPSignature.CASUAL_CERTIFICATION, PGPSignature.POSITIVE_CERTIFICATION or PGPSignature.CERTIFICATION_REVOCATION.

Parameters:

issuer - issuing component key

target - targeted userid

contentVerifierBuilderProvider - provider for content verifier builders

Throws:

PGPSignatureException - if an exception happens during signature verification

getTargetDisplay

protected String getTargetDisplay()

Specified by:
