A small, self-contained SHA512 and HMAC-SHA512 implementation in Rust.
Also includes SHA384 and HMAC-SHA384, that are just truncated versions of SHA512 with a different IV.
Optional features:
traits: enable support for the Digest trait from the digest crate.sha384: includes support for SHA384 and HMAC-SHA384.opt_size: enable size optimizations. Based on benchmarks, the .text
section size is reduced by 75%, at the cost of approximately 16% performance.
