(Swift) Use a Custom Set of Trusted Root CertificatesDemonstrates how to build a set of trusted root certificates to be used globally by all Chilkat classes. Note: This example requires Chilkat v11.0.0 or greater.
func chilkatTest() { var success: Bool = false // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. let trustedRoots = CkoTrustedRoots()! // Indicate that we will NOT trust any pre-installed certificates on the system. trustedRoots.trustSystemCaRoots = false // Thawte is a certificate authority that provides a .zip download of their // root CA certificates: https://www.thawte.com/roots/index.html // The direct download link is: https://www.verisign.com/support/thawte-roots.zip // Note: The above URLs are valid at the time of writing this example (29-May-2015). // Assuming the .zip has already been downloaded, open it and load each .pem file into // our trusted roots object. let zip = CkoZip()! // Open a .zip containing PEM files, among other things.. success = zip.open("qa_data/certs/thawte-roots.zip") if success == false { print("\(zip.lastErrorText!)") return } let entry = CkoZipEntry()! var pemStr: String? let cert = CkoCert()! var pattern: String? = "*.pem" var bHasMoreEntries: Bool = zip.entry(matching: pattern, entry: entry) while bHasMoreEntries == true { print("Entry: \(entry.fileName!)") // Get the PEM of the CA cert: pemStr = entry.unzip(toString: 0, srcCharset: "utf-8") // Load it into a certificate object: success = cert.loadPem(pemStr) if success != true { print("\(cert.lastErrorText!)") } // Add it to the trusted roots. trustedRoots.add(cert) bHasMoreEntries = entry.getNextMatch(pattern) } // Activate the trusted roots globally for all Chilkat objects. // This call really shouldn't fail, so we're not checking the return value. success = trustedRoots.activate() } |
