titus is a TLS/SSL proxy server (like stunnel or stud) that protects you from vulnerabilities in the TLS implementation such as Heartbleed (or worse).
Totally Isolated TLS Unwrapping Server
- Runs in a separate process from your application, protecting your application's state from compromise.
- Uses a separate process for every TLS connection, protecting the state of TLS connections from each other.
- Uses privilege separation and chrooting to protect your server as a whole.
- Isolates the private key in a dedicated process that doesn't talk to the network, protecting your private key from compromise.
- Can run in transparent proxy mode, preserving the client's IP address, so your backend doesn't even know it's there.
If there's a vulnerability in the TLS implementation, titus makes it very unlikely that an attacker could steal your private key, access the memory of your application, sniff data from other TLS connections, or otherwise attack your system.
The current version of titus is 0.3, released on 2015-11-28. titus aims to be bug-free and secure, though it is lacking in features and needs additional performance optimization. Additionally, we may make backwards-incompatible changes to the behavior before titus reaches version 1.0
