LTV verifier is used to verify signature in LTV work flow. Before use this class to verify signature(s), please ensure verify mode has been set by function LTVVerifier::SetVerifyMode.
Foxit PDF SDK has a default revocation callback for LTV verifier. If user wants to use customized revocation callback, please refer to function LTVVerifier::SetRevocationCallback.
If user wants to trust some certificates, please refer to function LTVVerifier::SetTrustedCertStoreCallback.
Enumeration for time type.
Values of this enumeration should be used alone.
|
explicit |
Constructor, with parameters.
[in] | document | A valid PDF document object. |
[in] | is_verify_signature | (Only available for LTVVerifier::e_VerifyModeAcrobat) Use to decide whether to verify signature validity when verifying signature or note. |
[in] | use_expired_tst | (Only available for LTVVerifier::e_VerifyModeAcrobat) Use to decide whether to use expired TST to verify signature or note. |
[in] | ignore_doc_info | (Only available for LTVVerifier::e_VerifyModeAcrobat) Use to decide whether to ignore the revocation information in DSS and signature or not. |
[in] | time_type | (Only available for LTVVerifier::e_VerifyModeAcrobat) Use to speicify the time type which is expected to be used for verifying. Please refer to values starting from LTVVerifier::e_SignatureCreationTime and this should be one of these values except LTVVerifier::e_VRICreationTime. |
foxit::pdf::LTVVerifier::LTVVerifier | ( | const LTVVerifier & | other | ) |
Constructor, with another LTV verifier object.
[in] | other | Another LTV verifier object. |
void foxit::pdf::LTVVerifier::AddDSS | ( | const SignatureVerifyResult & | signature_verify_result | ) |
Add the verify result (as VRI information) of a signature to the DSS.
[in] | signature_verify_result | A signature verify result to be added to DSS. |
bool foxit::pdf::LTVVerifier::IsEmpty | ( | ) | const |
Check whether current object is empty or not.
When the current object is empty, that means current object is useless.
bool foxit::pdf::LTVVerifier::operator!= | ( | const LTVVerifier & | other | ) | const |
Not equal operator.
[in] | other | Another LTV verifier object. This function will check if current object is not equal to this one. |
LTVVerifier& foxit::pdf::LTVVerifier::operator= | ( | const LTVVerifier & | other | ) |
Assign operator.
[in] | other | Another LTV verifier object, whose value would be assigned to current object. |
bool foxit::pdf::LTVVerifier::operator== | ( | const LTVVerifier & | other | ) | const |
Equal operator.
[in] | other | Another LTV verifier object. This function will check if current object is equal to this one. |
void foxit::pdf::LTVVerifier::SetRevocationCallback | ( | RevocationCallback * | callback | ) |
Set a customized pdf::RevocationCallback object.
If no customized revocation callback is set by this function, Foxit PDF SDK will use a default one.
[in] | callback | A customized revocation callback object, which is implemented based on callback class pdf::RevocationCallback. This should not be NULL. |
void foxit::pdf::LTVVerifier::SetTrustedCertStoreCallback | ( | TrustedCertStoreCallback * | callback | ) |
Set a customized pdf::TrustedCertStoreCallback object if user wants to trust some certificates.
If no trusted cert store callback object is set by this function, no certificate will be trusted during verifying process.
[in] | callback | A customized trusted cert store callback object, which is implemented based on callback class pdf::TrustedCertStoreCallback. This can be set to NULL which means not to use it. |
void foxit::pdf::LTVVerifier::SetVerifyMode | ( | VerifyMode | mode | ) |
Set the verifying mode to specify which validation process is to be used.
Please ensure to set the verify mode before doing verifying.
[in] | mode | The verify mode used for express verify process. Please refer to values starting from LTVVerifier::e_VerifyModeAcrobat and this should be one of these values. |
SignatureVerifyResultArray foxit::pdf::LTVVerifier::Verify | ( | ) |
Verify all the signatures in the PDF document which is used to constructed current object.
If verify mode is LTVVerifier::e_VerifyModeAcrobat, the verifying process will stop immediately when fail to verify any signature and return verify results for successfully verified signatures only. If verify mode is LTVVerifier::e_VerifyModeAcrobat, all the signatures will be verified and return verify results for all the signatures.
SignatureVerifyResultArray foxit::pdf::LTVVerifier::VerifySignature | ( | const Signature & | signature | ) |
Verify the target signature in the PDF document which is used to constructed current object.
[in] | signature | Target signature to be verified. If verify mode is LTVVerifier::e_VerifyModeAcrobat, this function will verify signatures until target signature. If verify mode is LTVVerifier::e_VerifyModeAcrobat, this function will only verify target signature. |
