Add a Private Key and Certificate Chain to a PFX

See more PFX/P12 Examples

Demonstrates Pfx.AddPrivateKey, which adds a private key together with its certificate chain to the PFX object.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

local chilkat = require("chilkat")

local pfx = chilkat.Pfx.new()

-- The file path is relative to the application's current working directory.  An absolute path
-- may also be used.  Supply the path appropriate to your own environment.
-- Load the private key.
local privKey = chilkat.PrivateKey.new()
local success = privKey:load_pem_file("qa_data/private_key.pem")
if not success then
    print(privKey.last_error_text)
    return
end

-- Load the certificate and build its chain of authority.  The chain must contain at least one
-- certificate; the certificate at index 0 is treated as the leaf.
local cert = chilkat.Cert.new()
success = cert:load_from_file("qa_data/cert.pem")
if not success then
    print(cert.last_error_text)
    return
end

local chain = chilkat.CertChain.new()
success = cert:build_cert_chain(chain)
if not success then
    print(cert.last_error_text)
    return
end

-- Add the private key and its certificate chain to the PFX.
success = pfx:add_private_key(privKey, chain)
if not success then
    print(pfx.last_error_text)
    return
end

print("Private key and certificate chain added to the PFX.")
