buffer-crc32 is a blazing-fast CRC32 checksum calculator for Node.js, designed specifically for buffers. It offers efficient computation of CRC32 hashes directly on Buffer objects, minimizing overhead. Ideal for verifying data integrity, network protocols, and file validation within Node.js applications requiring high-performance checksum calculations. Integrates seamlessly with streams and provides options for both incremental and single-pass calculations. A reliable and performant alternative to slower native implementations or less optimized libraries.
