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

loDsa = createobject("CkDsa")

// Load a PEM private key.

lcPemPrivateKey = loDsa.LoadText("dsa_priv.pem")
// Import the unencrypted PEM into the DSA object.
llSuccess = loDsa.FromPem(lcPemPrivateKey)
if (llSuccess <> .T.) then
    ? loDsa.LastErrorText
    release loDsa
    return
endif

// Write it out as a DER file:
llSuccess = loDsa.ToDerFile("dsa_priv.der")
if (llSuccess <> .T.) then
    ? loDsa.LastErrorText
    release loDsa
    return
endif

// Load an encrypted PEM private key.
