5//! This crate handles generating OpenTitan certificates.
6//!
7//! These certificates are generated from a template and embedded onto an
8//! OpenTitan device.
9//!
10//! Templates may specify that some values are variables, in which case they
11//! will be filled in by the device itself. This crate will generate C code for
12//! setting/getting variable values of templates from OpenTitan firmware.
13//!
14//! Certificates are generated in both X.509 format and CWT (CBOR web token)
15//! format. Details of the certificates will be available in the documentation
16//! in the future.
