Crate ring

source
Expand description

Safe, fast, small crypto using Rust with BoringSSL’s cryptography primitives.

§Feature Flags

Feature Description
alloc (default) Enable features that require use of the heap, RSA in particular.
std Enable features that use libstd, in particular std::error::Error integration. Implies `alloc`.
wasm32_unknown_unknown_js When this feature is enabled, for the wasm32-unknown-unknown target, Web APIs will be used to implement features like `ring::rand` that require an operating environment of some kind. This has no effect for any other target. This enables the `getrandom` crate's `js` feature.
