Interesting Discussions and Developments

Cryptographic Agility

Some very interesting work is happening in the Sigstore community around cryptographic agility. This includes support of further signature algorithms and the integration of post-quantum signatures schemes.

Community member William Woodruff had this to say about the work:

Over the past month, we’ve revisited the Configurable Crypto Algorithms proposal and have begun to work towards signature algorithm agility on various core Sigstore codebases (Fulcio, Rekor, cosign, sigstore-go, and the protobuf-specs). We’ve already made significant progress towards enabling agility within a safe set of signature suites, and are quickly moving towards a state where the public Sigstore instances will be able to handle Ed25519 keypairs and signatures. Longer term, we’ll be using that agility to investigate integrations of post-quantum signatures schemes, including hash-based signature schemes like LMS and LM-OTS (the latter being a perfect fit for Sigstore’s “keyless” model).

The original proposal can be found here

sigstore-python: DSSE support has landed!

Support for DSSE has been added to the sigstore-python library. This is a significant milestone for the project. The DSSE support is currently in a pre-release state and we welcome all feedback and contributions.

For those unfamiliar with DSSE (Dead Simple Signing Envelope), it is a protocol for signing and verifying software artifacts using an embedded payload that is passed over with a signature. This is in contrast to the traditional detached signature approach.

A release will be made shortly.
