The certificate validation policy file coming the downloaded api, provides standard controls for a certificate to be considered as valid. It uses only the certificates store as the source of trusted certificates. The certificate store contains legally valid root certificates. Therefore, in order to work with test certificates you have to define the root of the test certificates as trusted in the certificate validation policy file. You can see section Configuring The Policy at Run-time.

You can also specify the method of revocation control, via either OCSP or CRL. Validation of a certificate requires validation of the all certificates on the certificate chain. Not all of the certificates on the chain is available for OCSP query. So it is not possible to validate a certificate using only OCSP queries. By configuring the validation policy properly, validation operation first tries OCSP and if it is not available then tries CRL control for the certificate revocation check. In this case, the method that must be performed first must be placed before the other in the policy file.

The policy file can be edited after read from the file system. For example, the code below, demonstrates how to add TrustedCertificateFinderFromFileSystem to the validation policy at run-time.

ValidationPolicy POLICY = PolicyReader.readValidationPolicy(new FileInputStream(POLICY_FILE));

//For UEKAE Test Environment, we add our test roots.
HashMap<String, Object> parameters = new HashMap<String, Object>();
parameters.put("dizin", "T:\\MA3\\api-cmssignature\\testdata\\support\\UGRootCerts\\");
POLICY.bulmaPolitikasiAl().addTrustedCertificateFinder("tr.gov.tubitak.uekae.esya.api.certificate.validation.find.certificate.trusted.TrustedCertificateFinderFromFileSystem", parameters);

ValidationPolicy POLICY = PolicyReader.readValidationPolicy(POLICY_FILE);

//For UEKAE Test Environment, we add our test roots.
Dictionary<String, Object> parameters = new Dictionary<String, Object>();
parameters.Add("dizin", "T:\\MA3\\api-cmssignature\\testdata\\support\\UGRootCerts\\");
POLICY.bulmaPolitikasiAl().addTrustedCertificateFinder("tr.gov.tubitak.uekae.esya.api.certificate.validation.find.certificate.trusted.TrustedCertificateFinderFromFileSystem", parameters);

The classes that can be included in the policy file are listed in the table below. In this table, the character “*” in the section where possible values for a paramater are listed denotes the default value. The symbol [O] denotes that the parameter is optional. The XML tags next to each header shows the place where the classes under that header should be in the policy file.
