Tool to detect SHA-1 collisions in files, including SHAttered
historique
SHA-1 Collision Detection is an MIT-licensed C library and command-line tool by Marc Stevens and Dan Shumow. It computes SHA-1 digests while detecting files produced with known cryptanalytic SHA-1 collision techniques.
Marc Stevens and Dan Shumow published the implementation in 2017 in the context of practical SHA-1 collision attacks. Its detection method builds on Stevens's counter-cryptanalysis research and explicitly recognizes files produced by attacks such as SHAttered; later support also references SHA-mbles.
The project was designed as a near drop-in replacement for common SHA-1 implementations and sha1sum, lowering the cost of adding collision detection to existing software. The input confirms packaging as the Homebrew formula sha1dc.
sha1dcsum hashes files and warns when a full SHA-1 collision attack is detected; sha1dcsum_partialcoll also checks reduced-round collision examples. Developers can integrate the library through its SHA1DC API and use safe-hash mode so colliding inputs receive different defensive hashes.
sha1dc lets package and release engineers continue verifying legacy SHA-1 material while detecting known cryptanalytic collision constructions. It is particularly relevant to archives and software-distribution systems that cannot immediately remove every SHA-1 dependency.
posture de sécurité
narrow executable package without higher-risk signals.
risque vert · confiance faible · appliance
Avant une utilisation sans surveillance par un agent, vérifiez si l'outil lit des identifiants en clair, écrit un état distant, publie des artefacts ou lance des plugins.
