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.
