Usage:
    MobaXtermCipher.py <enc|dec> [-sysh sys_hostname] [-sysu sys_username]
                                 <-h conn_hostname> <-u conn_username>
                                 <plaintext|ciphertext>

    MobaXtermCipher.py <enc|dec> <-sp SessionP> <plaintext|ciphertext>

    MobaXtermCipher.py <enc|dec> <-p master_password> <plaintext|ciphertext>

        <enc|dec>                "enc" for encryption, "dec" for decryption.
                                 This parameter must be specified.

        [-sysh sys_hostname]     Hostname of system where MobaXterm runs.
                                 This parameter is optional. If not specified, use current system hostname.

        [-sysu sys_username]     Username of system where MobaXterm runs.
                                 This parameter is optional. If not specified, use current system username.

        <-h conn_hostname>       Hostname of MobaXterm connection config.
                                 This parameter must be specified.

        <-u conn_username>       Username of MobaXterm connection config.
                                 This parameter must be specified.

        <-sp SessionP>           The value `SessionP` stored in key HKCU\Software\Mobatek\MobaXterm
                                 This parameter must be specified.

        <-p master_password>     The master password set in MobaXterm.
                                 This parameter must be specified.

        <plaintext|ciphertext>   Plaintext string or ciphertext string.
                                 This parameter must be specified.

Usage:
    ShowMobaXterm.py [master_password]

        [master_password]        The master password set in MobaXterm.
                                 This parameter is optional, 
                                 but must be specified if you set a master password in MobaXterm.

MobaXterm will save passwords and credentials in:

If you have NOT set a master password in MobaXterm:

1. Credentials would look like:

   Name             Type        Data
   example.com      REG_SZ      root:bSj4VWbHezNH3tTY9Nil2RzJX57p7/S6KqMw8VsiT/WH+I8p03pqnInAu
   

   You can reveal credential by:

   $ ./MobaXtermCipher.py dec -sp 165821882556840 bSj4VWbHezNH3tTY9Nil2RzJX57p7/S6KqMw8VsiT/WH+I8p03pqnInAu
   HyperSine

   where 165821882556840 is the value SessionP stored in HKCU\Software\Mobatek\MobaXterm. Please modify it based on you environment.

2. Password would look like:

   Name                         Type        Data
   ssh22:[email protected]     REG_SZ      F0+wuBvbe9qPW6ypiOeYHTHhKdShRc/nXaM1Ky1jeTfw46TzQoSesX9buGm0WW36yP4lhH70ZCHZpEo4wLJhIl1
   

   You can reveal password by:

   $ ./MobaXtermCipher.py dec -sysh ShadowSurface -sysu DoubleSine -h 45.32.110.171 -u root F0+wuBvbe9qPW6ypiOeYHTHhKdShRc/nXaM1Ky1jeTfw46TzQoSesX9buGm0WW36yP4lhH70ZCHZpEo4wLJhIl1
   Lw3+cZ2s.w@U@f]U

   where ShadowSurface is my computer hostname and DoubleSine is my computer username.

   If the password is stored on your computer, -sysh and -sysu can be omitted.

   By the way, the example I give is a real SSH connection. But don't be happy too early, I've already delete that server.

3. All credentials and passwords can be revealed by ShowMobaXterm.py:

   $ ShowMobaXterm.py 12345678
   ------------------Credentials-------------------
   [*] Name:     example.com
   [*] Username: root
   [*] Password: HyperSine
   
   -------------------Passwords--------------------
   [*] Name:     ssh22:[email protected]
   [*] Password: Lw3+cZ2s.w@U@f]U
   
   [*] Name:     [email protected]
   [*] Password: Lw3+cZ2s.w@U@f]U

If you have set a master password in MobaXterm:

1. Credentials would look like:

   Name             Type        Data
   example.com      REG_SZ      root:0XROpGmLAYVx
   

   You can reveal credential by:

   $ ./MobaXtermCipher.py dec -p 12345678 0XROpGmLAYVx
   HyperSine

   where 12345678 is the master password you set.

2. Password would look like:

   Name                         Type        Data
   ssh22:[email protected]     REG_SZ      1du11XKQBOxud/FWh4ouWA==
   

   You can reveal password by:

   $ ./MobaXtermCipher.py dec -p 12345678 1du11XKQBOxud/FWh4ouWA==
   Lw3+cZ2s.w@U@f]U

   where 12345678 is the master password you set.

3. All credentials and passwords can be revealed by ShowMobaXterm.py:

   $ ShowMobaXterm.py 12345678
   ------------------Credentials-------------------
   [*] Name:     example.com
   [*] Username: root
   [*] Password: HyperSine
   
   -------------------Passwords--------------------
   [*] Name:     ssh22:[email protected]
   [*] Password: Lw3+cZ2s.w@U@f]U
   
   [*] Name:     [email protected]
   [*] Password: Lw3+cZ2s.w@U@f]U

   where 12345678 is the master password you set.
