local chilkat = require("chilkat")

-- This example requires the Chilkat API to have been previously unlocked.

local dsa = chilkat.Dsa.new()

-- Load a PEM public key.
local pemPublicKey = dsa:load_text("dsa_pub.pem")
-- Import the public key PEM into the DSA object.
local success = dsa:from_public_pem(pemPublicKey)
if not success then
    print(dsa.last_error_text)
    return
end

-- Write it out as a DER file:
success = dsa:to_public_der_file("dsa_pub.der")
if not success then
    print(dsa.last_error_text)
    return
end

print("Finished!")
