0.7.0 (current) does-not-implement-crypto, safe-to-run

From google/supply-chain copy of chromium. By Benjamin Gordon.

  • The libusb subdirectory contains a partial copy of libusb-1.0.27. I downloaded a copy from upstream and confirmed that there are no diffs.
  • build.rs calls pkg_config to probe for libusb-1.0 and sets up some build variables.
  • The files under src contain constants, extern declarations for libusb functions, and small helper functions that fill in some structs.

cargo-vet does not verify reviewers' identity. You have to fully trust the source the audits are from.

does-not-implement-crypto (implies crypto-safe)

Inspection reveals that the crate in question does not attempt to implement any cryptographic algorithms on its own.

Note that certification of this does not require an expert on all forms of cryptography: it's expected for crates we import to be "good enough" citizens, so they'll at least be forthcoming if they try to implement something cryptographic. When in doubt, please ask an expert.

crypto-safe
Implied by other criteria

All crypto algorithms in this crate have been reviewed by a relevant expert.

Note: If a crate does not implement crypto, use does-not-implement-crypto, which implies crypto-safe, but does not require expert review in order to audit for.

safe-to-run

This crate can be compiled, run, and tested on a local workstation or in controlled automation without surprising consequences. More…

May have been packaged automatically without a review

Lib.rs has been able to verify that all files in the crate's tarball, except Cargo.lock, are in the crate's repository. Please note that this check is still in beta, and absence of this confirmation does not mean that the files don't match.

Crates in the crates.io registry are tarball snapshots uploaded by crates' publishers. The registry is not using crates' git repositories, so there is a possibility that published crates have a misleading repository URL, or contain different code from the code in the repository.

To review the actual code of the crate, it's best to use cargo crev open libusb1-sys. Alternatively, you can download the tarball of libusb1-sys v0.7.0 or view the source online.
