Since Snapchat imposes few restrictions on what data can be uploaded (i.e., not just images), I've taken to using it as a system to send files to myself and others.

Snapchat FS is the tool that allows this. It provides a simple command line interface for uploading arbitrary files into Snapchat, managing them, and downloading them to any other computer with access to this package.

Uploading the file is simple:

$ sfs upload some_file.pdf
Uploading file some_file.pdf

Downloading is just as simple:

$ sfs download directory_to_put_files
Downloading snap file.txt
Downloading snap file.txt but filename is not unique; downloading as: file.txt-1a55ff534e03d25b5a489da83c2ae32ad9bc70fc6e07df4e7b0e82f028cb531f

Snapchat FS supports some other features, such as listing the files currently maintained in Snapchat using the Snapchat FS utility:

$ sfs list
Filename      Content hash
some_file.pdf fc7f9f7fd935c8f34...7df
cow.mov       1a55ff534e03d25b5...31f

• Uploading files via command line
• Downloading all the files all at once to an arbitrary file
• Downloading one file at a time
• Deleting files from Snapchat's server using the command line (to delete it you must "view" it in the app)
• Encrypting data with something other than the Snapchat default
• FUSE integration (yes yes I know I know)

sfs will boot up and look for the file ~/.snapchat_fs, which is a config file that we will use to store things like username and password. If it doesn't find the file, it will prompt you for your username and password. After you enter these things, it will create the config file and populate it with this information (NOTE: password is in PLAINTEXT).

This looks something like so:

Looks like you haven't used Snapchat FS before.
We're going to ask for a username and a password; you can
change these later by messing with the file /Users/alex/.snapchat_fs
Please enter a username:
bobby_murphy
Please enter your password (NOTE: STORED IN PLAINTEXT):

The sfs config file will then look something like this:

USERNAME=bobby_murphy
PASSWORD=iheartsnapchat

To add more to this config file, all you need to do is follow that format. Currently sfs is feature-sparse, so the only settings only include USERNAME and PASSWORD, but eventually it will allow you to do things like specify the encryption protocol to use when encrypting your data and sending it to the Snapchat servers.

The sfs file is a Python script that currently sits in the root directory and never moves, because there's no installation script. You can run it with a command like ./sfs. If you want to move into bin/ or something, you'll have to do it yourself.

In order to install dependencies: pip install -r requirements.txt

Someday this will be pip-installable or something.
