Trust management is a unified approach to specifying and interpreting security policies, credentials, and relationships; it allows direct authorization of security-critical actions. KeyNote credentials describe a specific delegation of trust and subsume the role of public key certificates; unlike traditional certificates, which bind keys to names, credentials can bind keys directly to the authorization to perform specific tasks.
Although I have developed pykeynote on Linux, and minimally tested it on OpenBSD, it will probably work on all Unix-like systems that satisfy the following requirements:
- Python version 2.3 or higher.
- Pyrex version 0.9.4 or higher (optional).
- The KeyNote trust management system (tested with version 2.3).
- The OpenSSL cryptographic toolkit (tested with version 0.9.8d).
