4. How to use the sample code

Make sure that you have installed Python3.

Make sure that you have installed pypiwin32, pycryptodome module.

Usage:
    XShellCryptoHelper.py <-e | -d>
                          [-ver    ver_sting]
                          [-user   user_string]

                          [-key    key_string]
                          <password_str | base64_str>

    <-e|-d>:                     Specify encryption(-e) or decryption(-d).

    [-ver ver_string]:           Specify version of session file.
                                 ver_string can be "5.1", "5.2", "6.0" and etc.
                                 If not specified, the latest version will be used.

Example:

1. Encrypt Password:

   $ XShellCryptoHelper.py -e -ver 5.0 "This is a test"
   /6KaTrKwm0cmhr0yAWQ=
   
   $ XFtpCryptoHelper.py -e -ver 5.0 "This is a test"
   TPKSg0QQ6o795vnPIMs=
   
   $ XShellCryptoHelper.py -e -ver 5.1 -sid S-1-5-21-917267712-1342860078-1792151419-512 "This is a test"
   hIMxIyQ3HbJsVIdbbunHvh7ZAvuN1NSJl8ZFL11+UJ+82+KAixa89O3OTAfRTg==
   
   $ XShellCryptoHelper.py -e -ver 5.3 -user Administrator -sid S-1-5-21-917267712-1342860078-1792151419-512 "This is a test"
   zv21O1x43qRs3c5NckDHvh7ZAvuN1NSJl8ZFL11+UJ+82+KAixa89O3OTAfRTg==
   
   $ XShellCryptoHelper.py -e -key 123123 "This is a test"
   Rrm3P3AL0iDV7nBbS2bHvh7ZAvuN1NSJl8ZFL11+UJ+82+KAixa89O3OTAfRTg==
   

2. Decrypt Password:

   $ XShellCryptoHelper.py -d -ver 5.0 /6KaTrKwm0cmhr0yAWQ=
   This is a test
   
   $ XFtpCryptoHelper.py -d -ver 5.0 TPKSg0QQ6o795vnPIMs=
   This is a test
   
   $ XShellCryptoHelper.py -d -ver 5.1 -sid S-1-5-21-917267712-1342860078-1792151419-512 hIMxIyQ3HbJsVIdbbunHvh7ZAvuN1NSJl8ZFL11+UJ+82+KAixa89O3OTAfRTg==
   This is a test
   
   $ XShellCryptoHelper.py -d -ver 5.3 -user Administrator -sid S-1-5-21-917267712-1342860078-1792151419-512 zv21O1x43qRs3c5NckDHvh7ZAvuN1NSJl8ZFL11+UJ+82+KAixa89O3OTAfRTg==
   This is a test
   
   $ XShellCryptoHelper.py -d -key 123123 Rrm3P3AL0iDV7nBbS2bHvh7ZAvuN1NSJl8ZFL11+UJ+82+KAixa89O3OTAfRTg==
