## Inputs
| Name | Required | Description |
| ------- | :------: | -------------------------------------------- |
| `crate` | ✓ | Name of crate as published to crates.io |
| `bin` | | Name of binary; default = same as crate name |
## Security considerations
Check the `.github/workflows` directory of this repo for the GitHub Actions
logic which compiles, signs, and publishes each binary.
This Action downloads both the binary executable and its signature. The
signature is verified using gpg and the public key available in
`signing-key.asc`. The corresponding private key is provided to this repo's
build jobs as a GitHub secret.
