Hashes

What is a Hash Generator?

A hash function takes any input — text, file, anything — and produces a fixed-size fingerprint. Tiny changes in the input produce a completely different fingerprint, but the same input always produces the same hash. That property makes hashing the workhorse of data integrity checks, password storage, content addressing, and digital signatures.

Algorithms available

  • MD5 — 128 bits. Fast but cryptographically broken; use only for non-security checksums.
  • SHA-1 — 160 bits. Deprecated for security; still common for Git object IDs.
  • SHA-256 — 256 bits. The current standard for general-purpose secure hashing.
  • SHA-384 — 384 bits. SHA-2 family, used in some TLS suites.
  • SHA-512 — 512 bits. Often faster than SHA-256 on 64-bit CPUs.

Features

  • Hash any text input — auto-updates as you type.
  • Drag-and-drop a file to hash it — streamed via a Web Worker so even large files don't freeze the page.
  • Toggle algorithms on/off to keep the output focused.
  • Compare two hashes side-by-side.

Privacy

Everything runs in your browser using the Web Crypto API for SHA family hashes and a pure-JS MD5 implementation for MD5. Your text and files never reach our server.
