Find a PFX Certificate by localKeyId

See more PFX/P12 Examples

Demonstrates Pfx.CertByLocalKeyId, which searches for a certificate whose certificate-bag localKeyId attribute matches a given value and copies it into a Cert object.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

func chilkatTest() {
    var success: Bool = false

    let pfx = CkoPfx()!

    //  The file path is relative to the application's current working directory.  An absolute path
    //  may also be used.  Supply the path appropriate to your own environment.
    //  The PFX password should come from a secure source rather than being hard-coded.
    var password: String? = "myPfxPassword"
    success = pfx.loadFile(path: "qa_data/identity.pfx", password: password)
    if success == false {
        print("\(pfx.lastErrorText!)")
        return
    }

    //  Find a certificate whose certificate-bag localKeyId attribute matches the given value.  The 2nd
    //  argument names the binary representation of the id, such as decimal, base64, or hex.
    let cert = CkoCert()!
    success = pfx.cert(byLocalKeyId: "01", encoding: "hex", cert: cert)
    if success == false {
        print("\(pfx.lastErrorText!)")
        return
    }

    print("Found certificate: \(cert.subjectCN!)")
