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

' {
'   "ssh_login": "2+qylFfC56Ck7OQQt/U2/w==",
'   "ssh_password": "5neIq9Jmn0E3p71N6Yc8TA=="
' }

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.JsonObject")

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Crypt2")
