Lua Requires Chilkat v9.5.0.71+

REST Basic Auth with Secure Strings

Demonstrates how to do REST Basic authentication using secure strings. Lua

local chilkat = require("chilkat")

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

-- Imagine we've previously saved our encrypted login and password within a JSON config file
-- that contains this:

-- {
--   "http_login": "mCrOmA7mBA7Au9RuJGb9hw==",
--   "http_password": "jJtiI9TgErTTpqBz9JtHBw=="
-- }

local json = chilkat.JsonObject.new()
json:load_file("qa_data/passwords/http.json")

local crypt = chilkat.Crypt2.new()

-- These are the encryption settings we previously used to encrypt the credentials within the JSON config file.
crypt.crypt_algorithm = "aes"
crypt.cipher_mode = "cbc"
crypt.key_length = 128
crypt:set_encoded_key("000102030405060708090A0B0C0D0E0F", "hex")
crypt:set_encoded_iv("000102030405060708090A0B0C0D0E0F", "hex")
crypt.encoding_mode = "base64"

local ssLogin = chilkat.SecureString.new()
local ssPassword = chilkat.SecureString.new()

-- Decrypt to the secure string.  (the strings will still held in memory encrypted, but are now encrypted using
-- a randomly generated session key.)
crypt:decrypt_secure_enc(json:string_of("http_login"), ssLogin)
crypt:decrypt_secure_enc(json:string_of("http_password"), ssPassword)

local rest = chilkat.Rest.new()

-- Connect to a REST server.
local bTls = true
local port = 443
local bAutoReconnect = true
local success = rest:connect("chilkatsoft.com", port, bTls, bAutoReconnect)

-- Cause the "Authorization: Basic ..." header to be added to HTTP requests
rest:set_auth_basic_secure(ssLogin, ssPassword)

local responseJson = rest:full_request_no_body("GET", "/helloWorld.html")
if not rest.last_method_success then
    print(rest.last_error_text)
    return
end

-- Show the LastRequestHeader that was sent.
print(rest.last_request_header)

-- The LastRequestHeader looks like this:

-- Host: chilkatsoft.com
-- Authorization: Basic bXlIdHRwTG9naW46bXlIdHRwUGFzc3dvcmQ=
