JavaScript-MD5 is a small, dependency-free implementation of the MD5 hashing algorithm written entirely in JavaScript, designed to run consistently across browsers, Node.js, and popular module loaders. It allows you to generate MD5 hashes from strings, arrays, ArrayBuffers, and other binary-like data types, making it useful for checksums, fingerprinting, and simple integrity checks on the client or server. The library is exposed as a plain function, so usage is as simple as calling md5(value) and receiving the 32-character hexadecimal hash. It supports multiple packaging formats, including UMD, making it easy to drop into legacy codebases as well as modern bundlers like webpack or Browserify. A comprehensive test suite and demo page are provided to validate behavior across platforms and edge cases.
