rs_sha512 0.1.3

`rs_sha512` is a Rust implementation of the SHA-512 cryptographic hash algorithm, part of the larger `rs_shield` project. This package provides SHA-512 hashing functionality in a standalone manner, ideal for when only SHA-512 is required. Alternatively, for those seeking a comprehensive set of cryptographic functions, this same algorithm is included within the broader `rs_shield` library bundle. The focus of `rs_sha512` and the larger project is on performance, safety, and openness, with a commitment to ongoing maintenance and enhancement.
