See more Certificates Examples

Loads a digital certificate from any format and saves to a binary DER encoded X.509 Certificate (.cer, .crt). Lua

local chilkat = require("chilkat")

local cert = chilkat.Cert.new()

-- LoadFromFile will load virtually any certificate format file.
-- It will auto-recognize the format and load appropiately.
-- In this case, load a PEM format certificate and convert to DER.
local success = cert:load_from_file("/Users/chilkat/testData/pem/chilkat.pem")
if not success then
    print(cert.last_error_text)
    return
end

success = cert:export_cert_der_file("chilkat.der")
if not success then
    print(cert.last_error_text)
    return
end

print("Converted certificate from PEM to DER format.")
