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

    ; Generate a 1024-bit key.  Chilkat RSA supports
    ; key sizes ranging from 512 bits to 4096 bits.

    If privKey.i = 0

    success = CkRsa::ckGenKey(rsa,1024,privKey)

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