Please consider adding BLAKE3 as an optional hash algorithm for verification.

MD5 is quite old and inefficient by modern standards. Its performance is significantly worse than BLAKE3, especially on NVMe SSDs, where hash calculation often becomes the primary bottleneck rather than disk I/O. BLAKE3 is designed for high throughput and excellent parallel scalability, making it much better suited for modern multi-core CPUs and high-speed storage. Adding BLAKE3 as an optional choice could significantly improve MultiPar’s creation and verification performance on contemporary systems.
