CSR Get Extension Request

See more CSR Examples

If a CSR contains a 1.2.840.113549.1.9.14 extensionRequest, then this method will return the extension request in XML format. Lua

local chilkat = require("chilkat")

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

local csr = chilkat.Csr.new()

-- Load a CSR PEM file.  The file should contain content that looks like this:
--
--     -----BEGIN CERTIFICATE REQUEST-----
--     MII...
--     ....
--     ....
--     ....
--     -----END CERTIFICATE REQUEST-----

local fac = chilkat.FileAccess.new()
local csrPem = fac:read_entire_text_file("qa_data/csr/sample.pem", "utf-8")

local success = csr:load_csr_pem(csrPem)
if not success then
    print(csr.last_error_text)
    return
end

local xml = chilkat.Xml.new()

success = csr:get_extension_request(xml)
if not success then
    print("CSR has no extensionRequest.")
    return
