Detailed Description

Class that allows you to verify a certificate against one or more Certificate Revocation Lists.

Constructor & Destructor Documentation

CRLVerifier()

iText.Signatures.CRLVerifier.CRLVerifier ( CertificateVerifier  verifier, IList< IX509Crl >  crls  )

inline

Creates a CRLVerifier instance.

Parameters

verifier	the next verifier in the chain
crls	a list of CRLs

Member Function Documentation

GetCRL()

virtual IX509Crl iText.Signatures.CRLVerifier.GetCRL ( IX509Certificate  signCert, IX509Certificate  issuerCert  )

inlinevirtual

Fetches a CRL for a specific certificate online (without further checking).

Parameters

signCert	the certificate
issuerCert	its issuer left for backwards compatibility

Returns

an X509CRL object.

IsSignatureValid()

virtual bool iText.Signatures.CRLVerifier.IsSignatureValid ( IX509Crl  crl, IX509Certificate  crlIssuer  )

inlinevirtual

Checks if a CRL verifies against the issuer certificate or a trusted anchor.

Parameters

crl	the CRL
crlIssuer	the trusted anchor

Returns

true if the CRL can be trusted

Verify() [1/2]

override IList<VerificationOK> iText.Signatures.CRLVerifier.Verify ( IX509Certificate  signCert, IX509Certificate  issuerCert, DateTime  signDate  )

inlinevirtual

Verifies whether a valid CRL is found for the certificate.

Verifies whether a valid CRL is found for the certificate. If this method returns false, it doesn't mean the certificate isn't valid. It means we couldn't verify it against any CRL that was available.

Parameters

signCert	the certificate that needs to be checked
issuerCert	its issuer

Returns

a list of VerificationOK objects. The list will be empty if the certificate couldn't be verified.

RootStoreVerifier.Verify(iText.Commons.Bouncycastle.Cert.IX509Certificate, iText.Commons.Bouncycastle.Cert.IX509Certificate, System.DateTime)

Reimplemented from iText.Signatures.CertificateVerifier.

Verify() [2/2]

virtual bool iText.Signatures.CRLVerifier.Verify ( IX509Crl  crl, IX509Certificate  signCert, IX509Certificate  issuerCert, DateTime  signDate  )

inlinevirtual

Verifies a certificate against a single CRL.

Parameters

crl	the Certificate Revocation List
signCert	a certificate that needs to be verified
issuerCert	its issuer
signDate	the sign date

Returns

true if the verification succeeded
