Swift sample showing how to generate an RSA key and export to encrypted PEM.

Note: This example requires Chilkat v11.0.0 or greater.

func chilkatTest() {
    var success: Bool = false

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    let rsa = CkoRsa()!

    // Generate a 1024-bit key.  Chilkat RSA supports
    // key sizes ranging from 512 bits to 4096 bits.
    let privKey = CkoPrivateKey()!
    success = rsa.genKey(1024, privKey: privKey)
    if success == false {
        print("\(rsa.lastErrorText!)")
        return
    }

    var strEncPem: String?
    strEncPem = privKey.getPkcs8EncryptedPem("myPassword")

    // You now have the private key in an encrypted format,
    // which may be (for example) saved to a database.

    print("\(strEncPem!)")
