# v3.0.0

Announcing the next major release of Cosign!

Cosign v3 is a minor change from Cosign v2.6.x, with all of the new capabilities of recent
releases **on by default**, but will still allow you to disable them if you need the older functionality.
These new features include support for the standardized bundle format (`--new-bundle-fomat`), providing roots
of trust for verification and service URLs for signing via one file (`--trusted-root`, `--signing-config`),
and container signatures stored as an OCI Image 1.1 referring artifact.

Learn more on our [v3 announcement blog post](https://blog.sigstore.dev/cosign-3-0-available/)! See
the changelogs for [v2.6.0](#v260), [v2.5.0](#v250), and [v2.4.0](#v240) for more information on recent
changes.

If you have any feedback, please reach out on Slack or file an issue on GitHub.

## Changes

* Default to using the new protobuf format (#4318)
* Fetch service URLs from the TUF PGI signing config by default (#4428)
* Bump module version to v3 for Cosign v3.0 (#4427)

# v2.6.1

## Bug Fixes

* Partially populate the output of cosign verify when working with new bundles (#4416)
* Bump sigstore-go, move conformance back to tagged release (#4426)

# v2.6.0

v2.6.0 introduces a number of new features, including:

* Signing an in-toto statement rather than Cosign constructing one from a predicate, along with verifying a statement's subject using a digest and digest algorithm rather than providing a file reference (#4306)
* Uploading a signature and its verification material (a ["bundle"](https://github.com/sigstore/protobuf-specs/blob/main/protos/sigstore_bundle.proto)) as an OCI Image 1.1 referring artifact, completing [#3927](https://github.com/sigstore/cosign/issues/3927) (#4316)
* Providing service URLs for signing and attesting using a [SigningConfig](https://github.com/sigstore/protobuf-specs/blob/4df5baadcdb582a70c2bc032e042c0a218eb3841/protos/sigstore_trustroot.proto#L185). Note that this is required when using a [Rekor v2](https://github.com/sigstore/rekor-tiles) instance (#4319)

Example generation and verification of a signed in-toto statement:

```
cosign attest-blob --new-bundle-format=true --bundle="digest-key-test.sigstore.json" --key="cosign.key" --statement="../sigstore-go/examples/sigstore-go-signing/intoto.txt"
cosign verify-blob-attestation --bundle="digest-key-test.sigstore.json" --key=cosign.pub --type=unused --digest="b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9" --digestAlg="sha256"
```

Example container signing and verification using the new bundle format and referring artifacts:

```
cosign sign --new-bundle-format=true ghcr.io/user/alpine@sha256:a19367999603840546b8612572e338ec076c6d1f2fec61760a9e11410f546733
cosign verify --new-bundle-format=true ghcr.io/user/alpine@sha256:a19367999603840546b8612572e338ec076c6d1f2fec61760a9e11410f546733
```

Example usage of a signing config provided by the public good instance's TUF repository:

```
cosign sign-blob --use-signing-config --bundle sigstore.json README.md
cosign verify-blob --new-bundle-format --bundle sigstore.json --certificate-identity $EMAIL --certificate-oidc-issuer $ISSUER --use-signed-timestamps README.md
```

v2.6.0 leverages sigstore-go's signing and verification APIs gated behind these new flags. In an upcoming major release, we will be
updating Cosign to default to producing and consuming bundles to align with all other Sigstore SDKs.

## Features

* Add to `attest-blob` the ability to supply a complete in-toto statement, and add to `verify-blob-attestation` the ability to verify with just a digest (#4306)
* Have cosign sign support bundle format (#4316)
* Add support for SigningConfig for sign-blob/attest-blob, support Rekor v2 (#4319)
* Add support for SigningConfig in sign/attest (#4371)
* Support self-managed keys when signing with sigstore-go (#4368)
* Don't require timestamps when verifying with a key (#4337)
* Don't load content from TUF if trusted root path is specified (#4347)
* Add a terminal spinner while signing with sigstore-go (#4402)
* Require exclusively a SigningConfig or service URLs when signing (#4403)
* Remove SHA256 assumption in sign-blob/verify-blob (#4050)
* Bump sigstore-go, support alternative hash algorithms with keys (#4386)

## Breaking API Changes

* `sign.SignerFromKeyOpts` no longer generates a key. Instead, it returns whether or not the client needs to generate a key, and if so, clients
should call `sign.KeylessSigner`. This allows clients to more easily manage key generation.

## Bug Fixes

* Verify subject with bundle only when checking claims (#4320)
* Fixes to cosign sign / verify for the new bundle format (#4346)

# v2.5.3

## Features

* Add signing-config create command (#4280)
* Allow multiple services to be specified for trusted-root create (#4285)
* feat: Add OCI 1.1+ experimental support to tree (#4205)

## Bug Fixes

* Fix cert verification logic for trusted-root/SCTs (#4294)
* force when copying the latest image to overwrite (#4298)
* avoid double-loading trustedroot from file (#4264)

# v2.5.2

* Bump TSA library to relax EKU chain validation rules (#4219)

## Bug Fixes

* Bump sigstore-go to pick up log index=0 fix (#4162)
* remove unused recursive flag on attest command (#4187)

## Docs

* Fix indentation in `verify-blob` cmd examples (#4160)

## Releases

* ensure we copy the latest tags on each release (#4157)

# v2.4.0

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

* Support for the newer Sigstore specification-compliant bundle format

* 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

# 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.

# v1.4.0

## Highlights

* BREAKING [COSIGN_EXPERIMENTAL]: This and future `cosign` releases will generate signatures that do not validate in older versions of `cosign`. This only applies to "keyless" experimental mode. To opt out of this behavior, use: `--fulcio-url=https://fulcio.sigstore.dev` when signing payloads (https://github.com/sigstore/cosign/pull/1127)
* BREAKING [cosign/pkg]: `SignedEntryTimestamp` is now of type `[]byte`. To get the previous behavior, call `strfmt.Base64(SignedEntryTimestamp)` (https://github.com/sigstore/cosign/pull/1083)
* `cosign-linux-pivkey-amd64` releases are now of the form `cosign-linux-pivkey-pkcs11key-amd64` (https://github.com/sigstore/cosign/pull/1052)
* Releases are now additionally signed using the keyless workflow (https://github.com/sigstore/cosign/pull/1073, https://github.com/sigstore/cosign/pull/1111)

## Enhancements

* Validate the whole attestation statement, not just the predicate (https://github.com/sigstore/cosign/pull/1035)
* Added the options to replace attestations using `cosign attest --replace` (https://github.com/sigstore/cosign/pull/1039)
* Added URI to `cosign verify-blob` output (https://github.com/sigstore/cosign/pull/1047)
* Signatures and certificates created by `cosign sign` and `cosign sign-blob` can be output to file using the `--output-signature` and `--output-certificate` flags, respectively (https://github.com/sigstore/cosign/pull/1016, https://github.com/sigstore/cosign/pull/1093, https://github.com/sigstore/cosign/pull/1066, https://github.com/sigstore/cosign/pull/1095)
* [cosign/pkg] Added the `pkg/oci/layout` package for storing signatures and attestations on disk (https://github.com/sigstore/cosign/pull/1040, https://github.com/sigstore/cosign/pull/1096)
* [cosign/pkg] Added `mutate` methods to attach `oci.File`s to `oci.Signed*` objects (https://github.com/sigstore/cosign/pull/1084)
* Added the `--signature-digest-algorithm` flag to `cosign verify`, allowing verification of container image signatures which were generated with a non-SHA256 signature algorithm (https://github.com/sigstore/cosign/pull/1071)

# 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!
