## What it is
cargo-crev is a cryptographically verifiable, distributed code review system for the Rust cargo package manager. It lets developers review dependencies and share signed reviews through a decentralized web of trust to verify the security and quality of crates.

## Use cases
- audit cargo dependencies for security before adding them
- sign and publish code reviews of rust crates
- verify that dependencies were reviewed by trusted developers
- protect a rust project against supply-chain attacks
- build a web of trust for crate reviews across a team
- check review provenance of transitive dependencies

## When to choose
- you maintain a Rust project and want to vet third-party crates
- you need decentralized, cryptographically signed dependency reviews
- your team wants to share trust decisions about crates without a central authority

## When to avoid
- you work outside the Rust/cargo ecosystem
- you need a centralized code review platform like GitHub pull requests
- you want automated vulnerability scanning rather than human review attestations

## Facets
- artifact type: cli-tool
- maturity: active
- function: code-review, security, cryptography, cli, dependency-audit
- domain: security, developer-tools, version-control
- platform: windows, cli, rust
- tags: supply-chain-security, rust, cargo, web-of-trust, decentralized, p2p, command-line, linux, macos
