X509CertStoreSearchGetNext (FUN) ¶ FUNCTION X509CertStoreSearchGetNext : RTS_IEC_HANDLE Search for the given certificate in the cert store. InOut: Scope Name Type Comment Return X509CertStoreSearchGetNext RTS_IEC_HANDLE Handle to the next certificate matching the filter criteria. Input hCertStore RTS_IEC_HANDLE Handle of to certificate store. hCert RTS_IEC_HANDLE Handle of the last found certificate. pFilters POINTER TO RtsX509CertFilter Pointer to array of filters to be applied. ui32NumOfFilters UDINT Number of applied filters. pResult POINTER TO RTS_IEC_RESULT

X509CertStoreUnregister (FUN) ¶ FUNCTION X509CertStoreUnregister : RTS_IEC_RESULT Unregister the component from the certificate store. This disables certificate generation for that specific use case. InOut: Scope Name Type Comment Return X509CertStoreUnregister RTS_IEC_RESULT Input hCertStore RTS_IEC_HANDLE Handle of to certificate store hRegisteredComponent RTS_IEC_HANDLE Handle to the entry retrieved by X509CertStoreRegister

X509CertVerify (FUN) ¶ FUNCTION X509CertVerify : RTS_IEC_RESULT Verify the given certificate. This verify checks only if the certificate itself is trusted using the certificates in the store. The verify checks if the certificate was added to the untrusted certs list. No subjects, key usages or other fields are verified. This has to be done by the application using this function. If the verify should use CRL to verify the certificates set the setting VerifyUseCRL to 1. This is disabled by default. InOut: Scope Name Type Comment Return X509CertVerify RTS_IEC_RESULT Result of the verification. Refer to ERR_CERT_ … error codes Input hCertStore RTS_IEC_HANDLE Handle of to certificate store. hCert RTS_IEC_HANDLE Certificate to verify.

X509CertVerify2 (FUN) ¶ FUNCTION X509CertVerify2 : RTS_IEC_RESULT Verify the given certificate. THIS verify checks only IF the certificate itself is trusted using the certificates in the store. The verify checks if the certificate was added to the untrusted certs list. No subjects, key usages or other fields are verified. This has to be done by the application using this function. This is disabled by default. InOut: Scope Name Type Comment Return X509CertVerify2 RTS_IEC_RESULT Result of certificate validation. One of the ERR_CERT_ … error codes. Input hCertStore RTS_IEC_HANDLE Handle of to certificate store. hCert RTS_IEC_HANDLE Certificate to verify. validationTimestamp SYSTIME The time-stamp used to verify the certificate. Same timebase as UtcHighresGet. If 0 the current time will be used. verificationFlags RtsX509VerifyFlags Flags to configure the verification process. See RTSX509VERIFYFLAGS for details.
