TElX509CertificateChain.Validate method

TElX509CertificateChain.Validate

Validates the certificate chain.

Declaration

[C#]
TSBCertificateValidity Validate(ref TSBCertificateValidityReason Reason, DateTime ValidityMoment);
TSBCertificateValidity Validate(ref TSBCertificateValidityReason Reason, bool CheckCACertDates, DateTime ValidityMoment);

[VB.NET]
Function Validate(ByRef Reason As TSBCertificateValidityReason, ByVal ValidityMoment As DateTime) As TSBCertificateValidity
Function Validate(ByRef Reason As TSBCertificateValidityReason, ByVal CheckCACertDates As Boolean, ByVal ValidityMoment As DateTime) As TSBCertificateValidity

[Pascal]
function Validate(var Reason: TSBCertificateValidityReason; ValidityMoment: TDateTime = 0): TSBCertificateValidity;
function Validate(var Reason: TSBCertificateValidityReason; CheckCACertDates: boolean; ValidityMoment: TDateTime = 0): TSBCertificateValidity;

[C++]
TSBCertificateValidity Validate(TSBCertificateValidityReason &Reason, int64_t ValidityMoment);
TSBCertificateValidity Validate(TSBCertificateValidityReason &Reason, bool CheckCACertDates, int64_t ValidityMoment);

[PHP]
integer Validate(integer &$Reason, DateTime $ValidityMoment)
integer Validate(integer &$Reason, bool $CheckCACertDates, DateTime $ValidityMoment)

[Java]
    TSBCertificateValidity validate(int[] Reason, Date ValidityMoment);
    TElCertificateValidityInfo validate(boolean CheckCACertDates, Date ValidityMoment);
    TSBCertificateValidity validate(int[] Reason, boolean CheckCACertDates, Date ValidityMoment);
    TElCertificateValidityInfo validate(Date ValidityMoment);

Parameters

Reason - certificate invalidity reason
ValidityMoment - moment for which the validity must be checked
CheckCACertDates - When this parameter is False, time specified in ValidityMoment is checked against validity period of the certificate being validated only.
When CheckCACertDates is True, validity periods of all certificates in the chain are questioned.
Default value is False.

Values

[.NET]	[Pascal]	[C++]	Description
vrBadData = 1	vrBadData	f_vrBadData = 1	Invalid certificate format or certificate is corrupted
vrRevoked = 2	vrRevoked	f_vrRevoked = 2	Certificate is revoked by Issuer
vrNotYetValid = 4	vrNotYetValid	f_vrNotYetValid = 4	Certificate is not valid yet
vrExpired = 8	vrExpired	f_vrExpired = 8	Certificate is expired
vrInvalidSignature = 16	vrInvalidSignature	f_vrInvalidSignature = 16	Certificate contains invalid digital signature, it could be corrupted
vrUnknownCA = 32	vrUnknownCA	f_vrUnknownCA = 32	Issuer (CA) certificate was not found.
vrCAUnauthorized = 64	vrCAUnauthorized	f_vrCAUnauthorized = 64	Issuer (CA) certificate was found but its key usage fields don't allow use of this certificate for signing other certificates.
vrCRLNotVerified = 128	vrCRLNotVerified	f_vrCRLNotVerified = 128	Certificate Revocation List for this certificate could not be retrieved and/or validated.
vrOCSPNotVerified = 256	vrOCSPNotVerified	f_vrOCSPNotVerified = 256	OCSP response for this certificate could not be retrieved and/or validated.
vrIdentityMismatch = 512	vrIdentityMismatch	f_vrIdentityMismatch = 512	Provided certificate doesn't include the specified name and / or IP address. Either the remote side in TLS or sender in S/MIME is misconfigured, or the certificate is misused by the remote side or sender, or authenticity of the remote side or sender is forged.
vrNoKeyUsage = 1024	vrNoKeyUsage	f_vrNoKeyUsage = 1024	Provided certificate may not be used for chosen activity (identifying TLS server or client or S/MIME message sender)
vrBlocked = 2048	vrBlocked	f_vrBlocked = 2048	Provided certificate has been found in the list of blocked certificates
vrFailure = 4096	vrFailure	f_vrFailure = 4096	Validation took too long, aborted
vrChainLoop = 8192	vrChainLoop	f_vrChainLoop = 8192	Certificate chain includes a loop. Further validation is not possible.
vrWeakAlgorithm = 16384	vrWeakAlgorithm	f_vrWeakAlgorithm = 16384	One of certificates is signed using the weak hash algorithm

Return value

Returns the certificate validity.

Possible values:

[.NET] [C++]	[Pascal]	Description
cvOk = 0	cvOk	Certificate was validated successfully and is valid
cvSelfSigned = 1	cvSelfSigned	Certificate is self signed
cvInvalid = 2	cvInvalid	Certificate is invalid
cvStorageError = 3	cvStorageError	Certificate was not validated due to certificate storage error
cvChainUnvalidated = 4	cvChainUnvalidated	Certificate chain was not validated because while the certificate itself is valid, one or more of CA Certificates in the chain have validation problems

Description

Use this method to validate a completed certificate chain. In a case when the chain is invalid, parameter Reason contains the invalidity reason.
