Sesto (abbreviation for Secret Store) is open source passwords (and general secrets) manager for web.
Sesto works on a Python server, when first accessed, serves users Google PNaCl module, which performs cryptographic protection and data management in user browser. This way, it enables strong cryptographic protection of secrets and passwords in your web browser (Google Chrome), so you can gain access to your passwords anywhere, safely.
Read blog post for description of Sesto, it's security model, architecture and some background experience.
Sesto is a proof-of-concept tool developed during Themis/WebThemis development to see how easy would it be to build sophisticated security schemes.
Sesto is licensed as Apache2 Open Source software.
WARNING: Sesto is proof-of-concept code. For industrial usage, it requires significant changes: some proper HTTP server (right now it runs on top of aiohttp), server authentication for client, shared secret management and a lot of infrastructure around. If you're interested in developing something more practical on top of Sesto, feel free to fork the project and drop us a line for help, we'll be glad to.
To run Sesto, you will need three things:
- Themis library compiled with Secure Comparator support
- Python 3.4+
- libssl-dev installed
git clone https://github.com/cossacklabs/themis
cd themis
make SECURE_COMPARATOR=enable
sudo make SECURE_COMPARATOR=enable insall
cd ..
git clone https://github.com/cossacklabs/sesto
cd sesto
pip3 install -r requirements.txt
python3 add_user.py test_user test_pass
python3 server.py
or
python3 server.py -v
to actually see what's going on.
Server will run on port 5103 of the machine you've launched it on.
There's a test user:
login: testuser
password: testpass
with test database to play around.
