プロジェクトの歴史

The maintainer, Hahwul, described creating jwt-hack in October 2020 as a Go tool born from a personal need to make JWT security testing more convenient, initially centered on cracking JWT signing secrets with wordlists or brute force. GitHub release metadata records v1.0.0 on August 31, 2020, which lines up with that early public project period.

On June 6, 2025, the maintainer announced jwt-hack v2 as a complete Rust rewrite. The stated motivations were better stability through Rust's ownership model and improved performance; later README material shows the Rust-era tool expanding into JWE support, DEFLATE-compressed JWT handling, scan mode, API server mode, Docker images, Snapcraft, and MCP server mode.

採用の歴史

jwt-hack's adoption is mainly within offensive-security, bug-bounty, and application-security workflows rather than general JWT debugging. Its README documents installation through Cargo, Homebrew, Snapcraft, source builds, GHCR, and Docker Hub, which makes it portable across local labs, CI jobs, and containerized testing environments.

使われ方

Typical use cases include decoding suspicious tokens, generating algorithm-confusion or header-based payloads, testing weak HMAC secrets with dictionaries or brute force, validating signatures, and running a scan that checks for weak secrets, missing claims, `none` algorithm acceptance, algorithm confusion, and header injection vectors.

パッケージ好きにとっての重要性

For package nerds, jwt-hack is the security-tool counterpart to simpler JWT viewers: it packages practical JWT attack primitives into a single installable CLI and shows the 2020s shift from Go security utilities toward Rust rewrites where maintainers care about memory safety and distributable binaries.

Related projects

• jwt-hack relates to JWT.io and jwt-cli for inspection and encoding, but it is closer in spirit to web-application security tools because it includes cracking, payload generation, and vulnerability scanning.
