A modern runtime for JavaScript and TypeScript.
ecdsa
Counted from the Cargo.toml manifests of the 40 indexed repositories that declare ecdsa as a dependency — not download counts. Dependency data last verified 2026-07-25.
Crates that show up unusually often in ecdsa projects. The most distinctive pairings rank first — crates these projects use far more than the average indexed Rust project does, not just crates that are popular everywhere. Each percentage is the share of ecdsa projects that also use it.
