wasg-register : Registers for a new Wireless@SG SSA account

wasg-register.py is a Python implementation of the Wireless@SG SSA registration protocol.

Please see this article for more information (note, article might be out of date due to API changes since it was written).

Dependencies

python3 -m pip install -r requirements.txt

Note: Requires a version of pycryptodome that supports AES in CCM mode.

Basic Usage

To create an account, you need to supply a valid mobile number (to which an OTP will be sent via SMS) and a date of birth. A mobile number / date of birth pair will be used to uniquely identify a user account.

# To use: python3 wasg-register.py <mobile number> <dob>
$ python3 wasg-register.py 659XXXXXXX 24031980
OTP will be sent to mobile phone number 659XXXXXXX
Enter OTP to continue: XXXXXX
Credentials:
 userid = 'XXX'
 password = 'XXX'

where dob is a date of birth in DDMMYYYY format.

If you have previously created an account with the same mobile number / date of birth pair, you can request for a new set of credentials using retrieve mode:

$ python3 wasg-register.py -r 659XXXXXXX 24031980
OTP will be sent to mobile phone number 659XXXXXXX
Enter OTP to continue: XXXXXX
Credentials:
 userid = 'XXX'
 password = 'XXX'

Docker

# Build
$ docker build -t wasg-register .

# Register mode
$ docker run -it --rm wasg-register 659XXXXXXX 24031980
