SparkMD5 is a fast JavaScript implementation of the MD5 hash algorithm, supporting both one-shot and incremental hashing. It works in browsers and Node.js, supports ArrayBuffer/typed arrays, and enables low-memory hashing of large files by appending chunks.

Use cases

• compute md5 hash of a string in the browser
• hash large files in chunks without loading them fully into memory
• incrementally build an md5 hash from streamed data
• hash ArrayBuffer or typed array data
• compute file checksums client-side before upload

When to choose

• you need fast md5 hashing in the browser
• you need incremental/chunked hashing of large files with low memory usage
• you need a library usable in both Node.js and browsers

When to avoid

• you need a cryptographically secure hash (md5 is broken for security purposes)
• you are in Node.js only and the built-in crypto module suffices
• you need modern algorithms like SHA-256
