MSE lib SGX bootstraps the execution of an encrypted ASGI/WSGI Python web application for Gramine.
The library is responsible for:
- Configuring the SSL certificates with either:
- RA-TLS, a self-signed certificate including the Intel SGX quote in an X.509 v3 extension
- Custom, the private key and full keychain is provided by the application owner
- No SSL, the secure channel may be managed elsewhere by an SSL proxy
- Decrypting Python modules encrypted with XSala20-Poly1305 AE
- Running the ASGI/WSGI Python web application with hypercorn
The flow to run an encrypted Python web application is the following:
- A first self-signed HTTPS server using RA-TLS is launched waiting to receive a JSON payload with:
- UUID, a unique application identifier provided to
mse-bootstrap
as an argument - the decryption key of the code
- Optionally the private key corresponding to the certificate provided to
mse-bootstrap
(for Custom certificate)
- UUID, a unique application identifier provided to
- If the UUID and decryption key are the expected one, the configuration server is stopped, the code is decrypted and finally run as a new server
$ pip install mse-lib-sgx

application
Bootstrap ASGI/WSGI Python web application for Gramine
positional arguments:
application ASGI application path (as module:app)
optional arguments:
-h, --help show this help message and exit
--host HOST hostname of the server
--port PORT port of the server
--subject SUBJECT Subject as RFC 4514 string for the RA-TLS certificate
--san SAN Subject Alternative Name in the RA-TLS certificate
--app-dir APP_DIR path of the python web application
--id ID identifier of the application as UUID in RFC 4122
--plaincode unencrypted python web application
--timeout TIMEOUT seconds before closing the configuration server
--version show program's version number and exit
--debug debug mode with more logging
--ratls EXPIRATION_DATE
generate a self-signed certificate for RA-TLS with a specific expiration date (Unix time)
--no-ssl use HTTP without SSL
--certificate CERTIFICATE_PATH
custom certificate used for the SSL connection, private key must be sent through the configuration server
