Cargo (Rust) signatures/Cargo.lock, RustSec
Definition
Cargo is the Rust package manager and build system that manages dependencies and builds for Rust projects. The Cargo.lock file is a key component that ensures reproducible builds by locking dependencies to specific versions. RustSec is a community-driven database of security advisories for Rust crates, which helps developers identify and mitigate vulnerabilities in their dependencies.
Secure Settings Example
# Cargo.toml
[dependencies]
serde = "1.0"
# Cargo.lock
# Ensure this file is committed to version control to lock dependencies
[[package]]
name = "serde"
version = "1.0.130"
source = "registry+https://github.com/rust-lang/crates.io-index"
Insecure Settings Example
# Cargo.toml
[dependencies]
serde = "1.0"
# Cargo.lock
# Not committing Cargo.lock can lead to non-reproducible builds
# and potential exposure to vulnerabilities in newer versions.
