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

    dsa := chilkat.NewDsa()

    // Load a DER private key.
    success := dsa.FromDerFile("dsa_priv.der")

    var pemStr *string = new(string)

    // Save to unencrypted PEM:
