# v2.4.0

v2.4.0 begins the modernization of the Cosign client, which includes:

* Support for the newer Sigstore specification-compliant bundle format
* Support for providing trust roots (e.g. Fulcio certificates, Rekor keys)
  through a trust root file, instead of many different flags
* Conformance test suite integration to verify signing and verification behavior

In future updates, we'll include:

* General support for the trust root file, instead of only when using the bundle
  format during verification
* Simplification of trust root flags and deprecation of the
  Cosign-specific bundle format
* Bundle support with container signing

We have also moved nightly Cosign container builds to GHCR instead of GCR.

## Features

* Add new bundle support to `verify-blob` and `verify-blob-attestation` (#3796)
* Adding protobuf bundle support to sign-blob and attest-blob (#3752)
* Bump sigstore/sigstore to support `email_verified` as string or boolean (#3819)
* Conformance testing for cosign (#3806)
* move incremental builds per commit to GHCR instead of GCR (#3808)
* Add support for recording creation timestamp for cosign attest (#3797)
* Include SCT verification failure details in error message (#3799)

# v2.0.0
This is the official 2.0.0 release of cosign!
There are many new features and breaking changes from version 1.x, for a full explanation please read the Cosign 2.0 [blog post](https://blog.sigstore.dev/).

## Breaking Changes
* `COSIGN_EXPERIMENTAL=1` is no longer required to have identity-based ("keyless") signing and transparency.
* By default, artifact signatures will be uploaded to Rekor, for both key-based and identity-based signing. To not upload to Rekor, include `--tlog-upload=false`.
  * You must also include `--insecure-ignore-tlog=true` when verifying an artifact that was not uploaded to Rekor.
  * Examples of when you may want to skip uploading to the transparency log are if you have a private Sigstore deployment that does not use transparency or a private artifact.
  * We strongly encourage all other use-cases to upload artifact signatures to Rekor. Transparency is a critical component of supply chain security, to allow artifact maintainers and consumers to monitor a public log for their artifacts and signing identities.
* Verification now requires identity flags, `--certificate-identity` and `--certificate-oidc-issuer`. Like verifying a signature with a public key, it's critical to specify who you trust to generate a signature for identity-based signing. See sigstore/cosign#2056 for more discussion on this change.
* --certificate-email has been removed. Use --certificate-identity, which supports not only email verification but also any identity specified in a certificate, including SPIFFE, GitHub Actions, or service account identities.
* Cosign no longer supports providing a certificate that does not conform to the Fulcio certificate profile, which includes setting the SubjectAlternativeName and OIDC Issuer OID. To verify with a non-conformant certificate, extract the public key from the certificate and verify with `cosign verify --key <key.pem>`. We are actively working on more support for custom certificates for those who want to bring their existing PKI.
* Signing OCI images by tag prints a warning and is strongly discouraged, e.g. `cosign sign container.registry.io/foo:tag`. This is considered insecure since tags are mutable. If you want to specify a particular image, you are recommended to do so by digest.
* SCT verification, a proof of inclusion in a certificate transparency log, is now on by default for verifying Fulcio certificates. For private deployments without certificate transparency, use `--insecure-ignore-sct=true` to skip this check.
* DSSE support in verify-blob has been removed. You can now verify attestations using verify-blob-attestation.
* Environment variable `SIGSTORE_TRUST_REKOR_API_PUBLIC_KEY` has been removed. For private deployments, if you would like to set the Rekor public key to verify transparency log entries, use either a TUF setup or set `SIGSTORE_REKOR_PUBLIC_KEY` with the PEM of the custom Rekor public key..
* verify-blob no longer searches for a certificate. You must provide one with either `--certificate` or `--bundle`.
* `cosign attest --type {custom|vuln}` (and `cosign verify-attestation`) will now use the RFC 3986 compliant URIs, adding https://, so that these predicate types are compliant with the in-toto specification.
* The CosignPredicate envelope that wraps the predicates of SPDX and CycloneDX attestations has been removed, which was a violation of the schema specified via the predicateType field (more information).
* `--force` has been removed. To skip any prompts, use `--yes`.

## Improvements
* Blob attestation and verification is now supported with cosign attest-blob and cosign verify-blob-attestation.
* You can now set flags via environment variables, for example instead of `--certificate-identity=email`, you can set an environment variable for `COSIGN_CERTIFICATE_IDENTITY=email`.
* `--offline=true` removes the fallback to the Rekor log when verifying an artifact. Previously, if you did not provide a bundle (a persisted response from Rekor), Cosign would fallback to querying Rekor. You can now skip this fallback for offline environments. Note that if the bundle fails to verify, Cosign will not fallback and will fail early.
* A Fulcio certificate can now be issued for self-managed keys by providing `--issue-certificate=true` with a key, `--key`, or security key, `--sk`. This is useful when adopting Sigstore incrementally.
* Experimental support for trusted timestamping has been added. Timestamping leverages a third party to provide the timestamp that will be used to verify short-lived Fulcio certificates, which distributes trust. We will be writing more about this in an upcoming blog post!
  * To use a timestamp when signing a container, use` cosign sign --timestamp-server-url=<url> <container>`, such as https://freetsa.org/tsr, and to verify, `cosign verify --timestamp-certificate-chain=<path-to-PEM-encodeded-chain> <other flags> <artifact>`.
  * To use a timestamp when signing a blob, use `cosign sign-blob --timestamp-server-url=<url> --rfc3161-timestamp=<output-path> --bundle=<output-path> <blob>`, and to verify, `cosign verify-blob --rfc3161-timestamp=<output-path> --timestamp-certificate-chain=<path-to-PEM-encoded-chain> --bundle=<output-path> <other flags> <blob>`.

# v1.12.1

> # Highlights
> * Pulls Fulcio root and intermediate when `--certificate-chain` is not passed into `verify-blob`. The v1.12.0 release introduced a regression: when `COSIGN_EXPERIMENTAL` was not set, cosign `verify-blob` would check a `--certificate` (without a `--certificate-chain` provided) against the operating system root CA bundle. In this release, Cosign checks the certificate against Fulcio's CA root instead (restoring the earlier behavior).

## Bug Fixes

* fix: fixing breaking changes in  rekor v1.12.0 upgrade (https://github.com/sigstore/cosign/pull/2260)
* Fixed bug where intermediate certificates were not automatically read from the OCI chain annotation (https://github.com/sigstore/cosign/pull/2244)
* fix: add COSIGN_EXPERIMENTAL=1 for verify-blob (https://github.com/sigstore/cosign/pull/2254)
* fix: fix cert chain validation for verify-blob in non-experimental mode (https://github.com/sigstore/cosign/pull/2256)
* fix: fix secret test, non-experimental bundle should pass (https://github.com/sigstore/cosign/pull/2249)
* Fix e2e test failure, add test for local bundle without rekor bundle (https://github.com/sigstore/cosign/pull/2248)

# v1.12.0

**Note: This release comes with a fix for `CVE-2022-36056` described in this [Github Security Advisory](https://github.com/sigstore/cosign/security/advisories/GHSA-8gw7-4j42-w388). Please upgrade to this release ASAP**

> # Highlights
> **BREAKING:** The fix for [GHSA-GHSA-8gw7-4j42-w388](https://github.com/sigstore/cosign/security/advisories/GHSA-8gw7-4j42-w388) (CVE-2022-36056) means that some `verify-blob` commands that used to work may not anymore. In particular:
> - When using `verify-blob` with signatures created with keyless mode, we require either `COSIGN_EXPERIMENTAL=1` or a valid Rekor bundle for offline verification passed with `--bundle`.
>
> If you upgrade and encounter other issues, please read the advisory in full; your prior checks may have been passing inappropriately.

* Allows base64 files as `--cert` in `cosign verify-blob` (https://github.com/sigstore/cosign/pull/1088)
* Kubernetes secrets generated for version >= 1.21 clusters have the immutable bit set (https://github.com/sigstore/cosign/pull/1091)
* Added `cosign save` and `cosign load` commands to save and upload container images and associated signatures to disk (https://github.com/sigstore/cosign/pull/1094)
* `cosign sign` will no longer fail to sign private images in keyless mode without `--force` (https://github.com/sigstore/cosign/pull/1116)
* `cosign verify` now supports signatures stored in files and remote URLs with `--signature` (https://github.com/sigstore/cosign/pull/1068)
* `cosign verify` now supports certs stored in files (https://github.com/sigstore/cosign/pull/1095)
* Added support for `syft` format in `cosign attach sbom` (https://github.com/sigstore/cosign/pull/1137)

## Bug Fixes

* Fixed verification of Rekor bundles for InToto attestations (https://github.com/sigstore/cosign/pull/1030)

    * `pkg/cosign/remote.UploadSignature` API was been removed in favor of new `pkg/oci/remote` APIs (https://github.com/sigstore/cosign/pull/774)
    * The function signature of `cosign.Verify` was changed so that callers must be explicit about which signatures (or attestations) to verify. For matching signatures, see also `cosign.Verify{Signatures,Attestations}` (https://github.com/sigstore/cosign/pull/782)
    * Removed `cremote.UploadFile` in favor of `static.NewFile` and `remote.Write` (https://github.com/sigstore/cosign/pull/797)

* Added shell auto-completion support (Clutch collab from @erkanzileli, @passcod, and @Dentrax! https://github.com/sigstore/cosign/pull/836)
* `cosign` has generated Markdown docs available in the `doc/` directory (https://github.com/sigstore/cosign/pull/839)
* Added support for verifying with secrets from a GitLab project (https://github.com/sigstore/cosign/pull/934)
* Added a `--k8s-keychain` option that enables cosign to support ambient registry credentials based on the "k8schain" library (https://github.com/sigstore/cosign/pull/972)

# v0.1.0

This is the first release of `cosign`!

The main goal of this release is to release something we can start using to sign other releases of [sigstore](sigstore.dev) projects, including `cosign` itself.

We expect many flags, commands, and formats to change going forward.
No backwards compatibility is promised or implied.

## Enhancements

This release added a feature to `cosign` called `cosign`.
The `cosign` feature can be used to sign container images and blobs.
Detailed documentation can be found in the [README](README.md) and the [Detailed Usage](USAGE.md).

## Bug Fixes

There was no way to sign container images. Now there is!
