Notebook","readme":"# DSSE: Dead Simple Signing Envelope\n\nSimple, foolproof standard for signing arbitrary data.\n\n## Features\n\n*   Supports arbitrary message encodings, not just JSON.\n*   Authenticates the message *and* the type to avoid confusion attacks.\n*   Avoids canonicalization to reduce attack surface.\n*   Allows any desired crypto primitives or libraries.\n\nSee [Background](background.md) for more information, including design\nconsiderations and rationale.\n\n## What is it?\n\nSpecifications for:\n\n*   [Protocol](protocol.md) (*required*)\n*   [Data structure](envelope.md), a.k.a. \"Envelope\" (*recommended*)\n*   (pending #9) Suggested crypto primitives\n\nOut of scope (for now at least):\n\n*   Key management / PKI /\n    [exclusive ownership](https://www.bolet.org/~pornin/2005-acns-pornin+stern.pdf)\n\n## Why not...?\n\n*   Why not raw signatures? Too fragile.\n*   Why not [JWS](https://tools.ietf.org/html/rfc7515)? Too many insecure\n    implementations and features.\n*   Why not [PASETO](https://paseto.io)? JSON-specific, too opinionated.\n*   Why not the legacy TUF/in-toto signature scheme? JSON-specific, relies on\n    canonicalization.\n\nSee [Background](background.md) for further motivation.\n\n## Who uses it?\n\n\u003c!-- Reminder: once in-toto and TUF switch to this new format, update the rest\nof the docs that currently reference the old format as \"current\", \"existing\",\netc. --\u003e\n\n*   [in-toto](https://in-toto.io) (as described in [ITE-5](https://github.com/in-toto/ITE/blob/master/ITE/5/README.adoc), [go](https://github.com/in-toto/go-witness/tree/main/dsse), [python](https://github.com/in-toto/in-toto/blob/d8fa07f5c3c3e052319b1a9b0c06408cdf5b5185/in_toto/common_args.py#L170))\n*   [TUF](https://theupdateframework.io) (pending implementation of [TAP-17](https://github.com/theupdateframework/taps/pull/138))\n*   [gittuf](https://gittuf.dev) (implemented with extensions in [go](https://github.com/gittuf/gittuf/tree/main/internal/third_party/go-securesystemslib/dsse))\n*   [Sigstore](https://sigstore.dev) supports DSSE as an [entry type](https://github.com/sigstore/rekor-tiles/blob/main/api/proto/rekor/v2/dsse.proto) in Rekor, Sigstore's transparency log\n*   [Chainguard Images](https://www.chainguard.dev/unchained/reproducing-chainguards-reproducible-image-builds) use sigstore and in-toto (see above), and support DSSE\n*   [GUAC](https://guac.sh/) [supports DSSE entries](https://github.com/guacsec/guac/blob/main/pkg/ingestor/parser/dsse/parser_dsse.go) as a data type\n*   [JFrog](https://jfrog.com/) has a [free DSSE Attestation Online Decoder Tool](https://dsse.io/)\n\n## How can we use it?\n\n* There is a Python implementation in [this repository](implementation/).\n* There's a DSSE library for Go in [go-securesystemslib](https://github.com/secure-systems-lab/go-securesystemslib/tree/main/dsse).\n* Sigstore includes a [Go implementation](https://github.com/sigstore/sigstore/tree/main/pkg/signature/dsse)\n  that supports hardware tokens, cloud KMS systems, and more.\n\n## Versioning\n\nThe DSSE specification follows semantic versioning, and is released using Git\ntags. The `master` branch points to the latest release. Changes to the\nspecification are submitted against the `devel` branch, and are merged into\n`master` when they are ready to be released.\n","funding_links":[],"categories":["Security"],"sub_categories":["Software Supply Chain Security"],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsecure-systems-lab%2Fdsse","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsecure-systems-lab%2Fdsse","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsecure-systems-lab%2Fdsse/lists"}
