wavekat-platform-client 0.0.8

//! Release-key tooling for the Ed25519 attestation scheme (see
//! `src/sign.rs`). Two subcommands, both meant to run in CI / by hand —
//! never in the shipped daemon. Gated behind the `release-tooling`
//! feature so it isn't part of the crate's default build surface; install
//! it with:
//!
//! ```text
//! cargo install wavekat-platform-client --bin release-keys --features release-tooling
//! ```
//!
//! ## One-time setup
//!
//! ```text
//! release-keys master
//! ```
//!
//! Prints the offline release master keypair. Store the **private** line
//! as a CI secret (`WK_RELEASE_MASTER_PRIVATE`); publish/commit the
//! **public** line as the platform's `RELEASE_MASTER_PUBKEY`. The private
//! key never touches the platform.
//!
//! ## Per release (in CI, with the master private key in the env)
//!
//! ```text
//! WK_RELEASE_MASTER_PRIVATE=<hex> release-keys issue 0.0.22
//! ```
//!
//! Generates a fresh per-version keypair, signs its certificate with the
//! master key, and prints three `KEY=value` lines to export into the
//! build environment so they're baked in via `option_env!`:
//!
//! ```text
//! WK_RELEASE_PRIV_V=<hex>   # per-version private key — sensitive
//! WK_RELEASE_PUB_V=<hex>    # per-version public key — not sensitive
//! WK_RELEASE_CERT=<hex>     # master signature over (version ‖ pub_v)
//! ```
//!
//! The version passed here MUST equal the build's `CARGO_PKG_VERSION`, or
//! the daemon's signature (which sends `CARGO_PKG_VERSION`) won't match
//! the certificate and the platform will reject it.
