REST Basic Auth with Secure Strings

Demonstrates how to do REST Basic authentication using secure strings.

This example requires Chilkat v9.5.0.71 or greater.

VB.NET

Dim success As Boolean = False

' 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=="
' }

Dim json As New Chilkat.JsonObject
json.LoadFile("qa_data/passwords/http.json")

Dim crypt As New Chilkat.Crypt2

' These are the encryption settings we previously used to encrypt the credentials within the JSON config file.
crypt.CryptAlgorithm = "aes"
crypt.CipherMode = "cbc"
crypt.KeyLength = 128
crypt.SetEncodedKey("000102030405060708090A0B0C0D0E0F","hex")
crypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex")
crypt.EncodingMode = "base64"

Dim ssLogin As New Chilkat.SecureString
Dim ssPassword As New Chilkat.SecureString

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

Dim rest As New Chilkat.Rest

' Connect to a REST server.
Dim bTls As Boolean = True
Dim port As Integer = 443
Dim bAutoReconnect As Boolean = True
success = rest.Connect("chilkatsoft.com",port,bTls,bAutoReconnect)

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

Dim responseJson As String = rest.FullRequestNoBody("GET","/helloWorld.html")
If (rest.LastMethodSuccess <> True) Then
    Debug.WriteLine(rest.LastErrorText)
    Exit Sub
End If


' Show the LastRequestHeader that was sent.
Debug.WriteLine(rest.LastRequestHeader)

' The LastRequestHeader looks like this:

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