WFH - Web File Hasher

A utility for getting the MD5 hash of files in web browsers. The MD5 hashing is done via WebAssembly, and the utility supports incrementally hashing large files via streaming for memory efficiency.

Requirements

• Rust >= 1.62
• Cargo >= 1.62
• The wasm32-unknown-unknown target must be installed to compile the wfh_wasm crate
• Node.js >= 16
• pnpm >= 7

Directories

• wfh - file hashing library
• wfh_cf_page - example web page using wfh to hash files
• wfh_wasm - Rust crate wrapping the md-5 crate, compiled down to WebAssembly
