BLAKE3
BLAKE3 is a high-performance implementation of the BLAKE3 cryptographic hash algorithm used for calculating secure data digests and fingerprints. It functions as a parallel cryptographic hash tool that distributes workloads across multiple processor threads to process large datasets rapidly.
The project provides specialized tools for keyed hashing and the generation of message authentication codes. It also includes functionality for cryptographic key derivation, allowing the creation of unique secret sub-keys from a master key and context strings.
The implementation supports data integrity verification through parallel hash computation and verified data streaming. These capabilities are provided as a cross-language library for Rust and C environments and include a command-line interface for computing digests of files or standard input.

Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
