Buffer CRC32

buffer-crc32 provides a pure JavaScript implementation of the CRC32 algorithm, designed to work seamlessly with binary data and various character encodings by internally casting strings to Buffers. It offers methods to compute the CRC32 checksum and retrieve results as raw Buffer objects, signed integers, or unsigned integers. The library also supports an "append mode," allowing for incremental CRC calculations across multiple data chunks. Currently at version 1.0.0, this package has not seen updates in approximately seven years, suggesting it is stable but effectively abandoned. It requires Node.js version 8.0.0 or higher, potentially posing compatibility challenges for very modern environments that are primarily ESM-based or require newer Node.js features. Its key differentiator is its self-contained, pure JavaScript nature, avoiding native module dependencies.
