Convert to DER encoded X.509 Certificate (.cer, .crt)

See more Certificates Examples

Loads a digital certificate from any format and saves to a binary DER encoded X.509 Certificate (.cer, .crt). Swift

func chilkatTest() {
    var success: Bool = false

    let cert = CkoCert()!

    // LoadFromFile will load virtually any certificate format file.
    // It will auto-recognize the format and load appropiately.
    // In this case, load a PEM format certificate and convert to DER.
    success = cert.load(fromFile: "/Users/chilkat/testData/pem/chilkat.pem")
    if success != true {
        print("\(cert.lastErrorText!)")
        return
    }

    success = cert.exportDerFile(path: "chilkat.der")
    if success != true {
        print("\(cert.lastErrorText!)")
        return
    }

    print("Converted certificate from PEM to DER format.")
