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 .

inline |
Constructor, with parameters.
[in] | document | A valid PDF document object. |
[in] | is_verify_signature | (Only available for foxit.pdf.LTVVerifier.VerifyMode.e_VerifyModeAcrobat ) Use to decide whether to verify signature validity when verifying signature or note. |
[in] | use_expired_tst | (Only available for foxit.pdf.LTVVerifier.VerifyMode.e_VerifyModeAcrobat ) Use to decide whether to use expired TST to verify signature or note. |
[in] | ignore_doc_info | (Only available for foxit.pdf.LTVVerifier.VerifyMode.e_VerifyModeAcrobat ) Use to decide whether to ignore the revocation information in DSS and signature or not. |
[in] | time_type | (Only available for foxit.pdf.LTVVerifier.VerifyMode.e_VerifyModeAcrobat ) Use to speicify the time type which is expected to be used for verifying. Please refer to values starting from foxit.pdf.LTVVerifier.TimeType.e_SignatureCreationTime and this should be one of these values except foxit.pdf.LTVVerifier.TimeType.e_VRICreationTime . |
|
inline |
Constructor, with another LTV verifier object.
[in] | other | Another LTV verifier object. |
|
inline |
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. |
|
inline |
Check whether current object is empty or not.
When the current object is empty, that means current object is useless.
|
inline |
Set a customized foxit.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 foxit.pdf.RevocationCallback . This should not be null. |
|
inline |
Set a customized foxit.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 foxit.pdf.TrustedCertStoreCallback . This can be set to null which means not to use it. |
|
inline |
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 foxit.pdf.LTVVerifier.VerifyMode.e_VerifyModeAcrobat and this should be one of these values. |
|
inline |
Verify all the signatures in the PDF document which is used to constructed current object.
If verify mode is foxit.pdf.LTVVerifier.VerifyMode.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 foxit.pdf.LTVVerifier.VerifyMode.e_VerifyModeAcrobat , all the signatures will be verified and return verify results for all the signatures.
|
inline |
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 foxit.pdf.LTVVerifier.VerifyMode.e_VerifyModeAcrobat , this function will verify signatures until target signature. If verify mode is foxit.pdf.LTVVerifier.VerifyMode.e_VerifyModeAcrobat , this function will only verify target signature. |
