Module biscuit_auth::crypto

cryptographic operations

Biscuit tokens are based on aggregated gamma signatures. This provides the fundamental operation for offline delegation: from a message and a valid signature, it is possible to add a new message and produce a valid signature for the whole.

The implementation is based on curve25519_dalek, a Rust implementation of the Ristretto group over Ed25519.
