- Inherits From:
- GPGSignature : NSObject
- Declared In:
- GPGME/GPGKeySignature.h
The signatures on a key are only available if the key was retrieved via a listing operation with the GPGKeyListModeSignatures mode enabled, because it is expensive to retrieve all signatures of a key.
GPGKeySignature instances are returned by -[GPGUserID signatures]; you should never need to instantiate yourself objects of that class. It is guaranteed that the owning GPGUserID instance will never be deallocated before the GPGKeySignature has been deallocated, without creating non-breakable retain-cycles.
An instance represents a signature on a user ID of a key.
Key signatures raise a NSInternalInconsistencyException when methods -fingerprint, -summary, -notations, -policyURLs, -validity, -validityError, -wrongKeyUsage, -validityDescription, -hashAlgorithm, -hashAlgorithmDescription are invoked.

- (NSString *)comment
Returns the comment on the signer's key, if available. Taken from the main user ID of the signer's key.
- (NSCalendarDate *)creationDate
Returns signature creation date. Returns nil when not available or invalid.
- (NSString *)email
Returns the email address on the signer's key, if available. Taken from the main user ID of the signer's key.
- (NSCalendarDate *)expirationDate
Returns signature expiration date. Returns nil when not available or invalid.
- (BOOL)hasSignatureExpired
Returns whether signature has expired or not.
- (BOOL)isExportable
Returns whether signature is exportable or not (locally signed).
- (BOOL)isRevocationSignature
Returns whether the signature is a revocation signature or not.
- (BOOL)isSignatureInvalid
Returns whether signature is invalid or not.
- (NSString *)name
Returns the name on the signer's key, if available. Taken from the main user ID of the signer's key.
- (GPGUserID *)signedUserID
Returns the GPGUserID signed by this signature.
- (NSString *)signerKeyID
Returns the key ID of the signer's key.
- (GPGError)status
Returns signature status.
In particular, the following status codes are of interest:
| GPGErrorNoError | This status indicates that the signature is valid. |
| GPGErrorSignatureExpired | This status indicates that the signature is valid but expired. |
| GPGErrorKeyExpired | This status indicates that the signature is valid but the key used to verify the signature has expired. |
| GPGErrorBadSignature | This status indicates that the signature is invalid. |
| GPGErrorNoPublicKey | This status indicates that the signature could not be verified due to a missing key. |
| GPGErrorGeneralError | This status indicates that there was some other error which prevented the signature verification. |
- (NSString *)userID
Returns the main user ID of the signer's key.
