A crate to interact with [sigstore](https://sigstore.dev/).
This crate is under active development and will not be considered
stable until the 1.0 release.
## Features
### Cosign Sign and Verify
The crate implements the following verification mechanisms:
* Sign using a cosign key and store the signature in a registry
* Verify using a given key
* Verify bundle produced by transparency log (Rekor)
* Verify signature produced in keyless mode, using Fulcio Web-PKI
Signature annotations and certificate email can be provided at verification time.
### Fulcio Integration
For use with Fulcio ephemeral key signing, an OpenID connect API is available,
along with a fulcio client implementation.
### Rekor Client
All rekor client APIs can be leveraged to interact with the transparency log.
### Key Interface
Cryptographic key management with the following key interfaces:
* Generate a key pair
* Sign data
* Verify signature
* Export public / (encrypted) private key in PEM / DER format
* Import public / (encrypted) private key in PEM / DER format
#### Known limitations
* The crate does not handle verification of attestations yet.
## Examples
The `examples` directory contains demo programs using the library.
* [`openidflow`](examples/openidflow/README.md)
* [`key_interface`](examples/key_interface/README.md)
* [`rekor`](examples/rekor/README.md)
* [`cosign/verify`](examples/cosign/verify/README.md)
* [`cosign/verify-blob`](examples/cosign/verify-blob/README.md)
* [`cosign/verify-bundle`](examples/cosign/verify-bundle/README.md)
* [`cosign/sign`](examples/cosign/sign/README.md)
Each example can be executed with the `cargo run --example <name>` command.
For example, `openidconnect` can be run with the following command:
```bash
cargo run --example openidconnect
```
## WebAssembly/WASM support
To embedded this crate in WASM modules, build it using the `wasm` cargo feature:
```bash
cargo build --no-default-features --features wasm --target wasm32-unknown-unknown
```
NOTE: The wasm32-wasi target architecture is not yet supported.
