sigstore framework
sigstore/sigstore contains common Sigstore code: that is, code shared by infrastructure (e.g., Fulcio and Rekor) and Go language clients (e.g., Cosign and Gitsign).
This library currently provides:
- A signing interface (support for ecdsa, ed25519, rsa, DSSE (in-toto))
- OpenID Connect fulcio client code
The following KMS systems are available:
- AWS Key Management Service
- Azure Key Vault
- HashiCorp Vault
- Google Cloud Platform Key Management Service

For example code, look at the relevant test code for each main code file.
