Verify Docker Image Signature All LiteLLM Docker images are signed with cosign. Every release is signed with the same key introduced in commit `0112e53`. Verify using the pinned commit hash (recommended): A commit hash is cryptographically immutable, so this is the strongest way to ensure you are using the original signing key: ```bash cosign verify \ --key https://raw.githubusercontent.com/BerriAI/litellm/0112e53046018d726492c814b3644b7d376029d0/cosign.pub \ ghcr.io/berriai/litellm:v1.91.0-dev.1 ``` Verify using the release tag (convenience): Tags are protected in this repository and resolve to the same key.

This option is easier to read but relies on tag protection rules: ```bash cosign verify \ --key https://raw.githubusercontent.com/BerriAI/litellm/v1.91.0-dev.1/cosign.pub \ ghcr.io/berriai/litellm:v1.91.0-dev.1 ``` Expected output: ``` The following checks were performed on each of these signatures: The cosign claims were validated The signatures were verified against the specified public key ``` --- What's Changed feat(auth): resolve caller identity once into a Principal at the auth seam by @yassin-berriai in https://github.com/BerriAI/litellm/pull/30887 feat(fireworks_ai)…
