Detailed Description

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 fsdk.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 fsdk.LTVVerifier.SetRevocationCallback .
If user wants to trust some certificates, please refer to function fsdk.LTVVerifier.SetTrustedCertStoreCallback .

Member Function Documentation

◆ AddDSS()

def fsdk.LTVVerifier.AddDSS (   signature_verify_result)

Add the verify result (as VRI information) of a signature to the DSS.

Parameters
[in]signature_verify_resultA signature verify result to be added to DSS.
Returns
None.

◆ IsEmpty()

def fsdk.LTVVerifier.IsEmpty ( )

Check whether current object is empty or not.

When the current object is empty, that means current object is useless.

Returns
true means current object is empty, while false means not.

◆ SetRevocationCallback()

def fsdk.LTVVerifier.SetRevocationCallback (   callback)

Set a customized fsdk.RevocationCallback object.

If no customized revocation callback is set by this function, Foxit PDF SDK will use a default one.

Parameters
[in]callbackA customized revocation callback object, which is implemented based on callback class fsdk.RevocationCallback . This should not be null.
Returns
None.

◆ SetTrustedCertStoreCallback()

def fsdk.LTVVerifier.SetTrustedCertStoreCallback (   callback)

Set a customized fsdk.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.

Parameters
[in]callbackA customized trusted cert store callback object, which is implemented based on callback class fsdk.TrustedCertStoreCallback . This can be set to null which means not to use it.

◆ SetVerifyMode()

def fsdk.LTVVerifier.SetVerifyMode (   mode)

Set the verifying mode to specify which validation process is to be used.

Please ensure to set the verify mode before doing verifying.

Parameters
[in]modeThe verify mode used for express verify process. Please refer to values starting from fsdk.LTVVerifierE_VerifyModeAcrobat and this should be one of these values.
Returns
None.

◆ Verify()

def fsdk.LTVVerifier.Verify ( )

Verify all the signatures in the PDF document which is used to constructed current object.

If verify mode is fsdk.LTVVerifierE_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 fsdk.LTVVerifierE_VerifyModeAcrobat , all the signatures will be verified and return verify results for all the signatures.

Returns
An array of signature verify results.

◆ VerifySignature()

def fsdk.LTVVerifier.VerifySignature (   signature)

Verify the target signature in the PDF document which is used to constructed current object.

Parameters
[in]signatureTarget signature to be verified. If verify mode is fsdk.LTVVerifierE_VerifyModeAcrobat , this function will verify signatures until target signature. If verify mode is fsdk.LTVVerifierE_VerifyModeAcrobat , this function will only verify target signature.
Returns
An array of signature verify result.
