-Libtrust is library for managing authentication and authorization using public key cryptography.
-
-Authentication is handled using the identity attached to the public key.
-Libtrust provides multiple methods to prove possession of the private key associated with an identity.
- - TLS x509 certificates
- - Signature verification
- - Key Challenge
-
-Authorization and access control is managed through a distributed trust graph.
-Trust servers are used as the authorities of the trust graph and allow caching portions of the graph for faster access.
