Bug: 254153648 Test: mmm external/rust/crates/zeroize Merged-In: I5b72ed47c0cc2545b0cf25009671a145f2e2c7d2 Change-Id: I9a933f284773b0242f1d0f10d36b64416bb4f01a (cherry picked from commit I9a933f284773b0242f1d0f10d36b64416bb4f01a)
Securely zero memory (a.k.a. zeroize) while avoiding compiler optimizations.
This crate implements a portable approach to securely zeroing memory using techniques which guarantee they won't be “optimized away” by the compiler.
The Zeroize trait is the crate's primary API.
Zeroing memory securely is hard - compilers optimize for performance, and in doing so they love to “optimize away” unnecessary zeroing calls. There are many documented “tricks” to attempt to avoid these optimizations and ensure that a zeroing routine is performed reliably.
This crate isn‘t about tricks: it uses core::ptr::write_volatile and core::sync::atomic memory fences to provide easy-to-use, portable zeroing behavior which works on all of Rust’s core number types and slices thereof, implemented in pure Rust with no usage of FFI or assembly.
#![no_std] i.e. embedded-friendly!Rust 1.51 or newer.
In the future, we reserve the right to change MSRV (i.e. MSRV is out-of-scope for this crate's SemVer guarantees), however when we do it will be accompanied by a minor version bump.
