⚡ Performance & TurboFan JIT Optimization

• Native ROR Recognition: Migrated bit rotation from ROL to ROR (>>> cnt | a << 32 - cnt) with updated shift string table "94/*;72,<50):61+". This allows V8 TurboFan to natively recognize the rotation pattern and emit a single x86 rorl instruction instead of multiple shift/or instructions.
• Loop-Invariant Register Hoisting (mul & add): Hoisted round multiplier and adder calculations (let mul = 0x7351 >> l, add = 0x0510 >> l) directly into the inner for header. This eliminates 4 shift instructions and memory loads per step in the hot loop, ensuring optimal register allocation and yielding an immediate speedup.
• Inlined Endianness Check (reverseOnBE): Inlined the isBE check directly into reverseOnBE (a => isBE ? a.reverse() : a) instead of writing isBE && before every call site, enabling cleaner expression nesting and saving code size.

🧩 Expanded Input Types

• Added official support for Int8Array and number[] inputs in both MD5 and HMAC-MD5 (elements are safely cast to bytes via Uint8Array).
• Updated TypeScript declarations (main.d.ts), JSDoc (@typedef Input), and README.md with usage examples.

🛠️ Tooling & Dependencies

• Updated terser to ^5.51.2 and es-check to ^9.7.1.
• Added tsconfig.nocheck.json composite project reference for minified files.
• Added comprehensive test cases for Int8Array and number[] in scripts/test.mjs.
• Added to CDNJS (cdnjs/packages#2199).

• ⚡ Optimize & Eliminate JIT Deopt: Simplified inputToWords and output formatting. Replaced the old big-endian JS bitwise loop with native TypedArray .reverse(), completely eliminating JIT deoptimization (bailout) risks and keeping type feedback clean and monomorphic.
• 📊 Benchmark:
  • Added spark-md5 to benchmarks.
  • Fixed js-md5 silently delegating to node:crypto in Node.js, ensuring a fair pure-JS benchmark.
  • tinyhmacmd5 remains the fastest pure-JS MD5 / HMAC-MD5 implementation.
• 📝 Updated package description: "A tiny, fast and reliable implementation of MD5 and HMAC-MD5 for JavaScript."
