Security Notice

MD5 and SHA-1 are cryptographically broken and should not be used for security purposes. Use SHA-256 or SHA-512 for secure applications. Hashes cannot be "decoded" - they are one-way functions.

Hash Generator - MD5, SHA1, SHA256 Online Tool

A hash generator computes digests (MD5, SHA‑1, SHA‑256, SHA‑512) from text and files to verify integrity and detect changes. Use it to check downloads, compare artifacts, and produce checksums for release notes and CI pipelines.

What is a hash?

A hash function deterministically converts input bytes into a short, fixed‑length output. Good hash functions are collision‑resistant (hard to find two inputs with the same digest), preimage‑resistant (hard to find an input from a digest), and fast to compute. Popular choices include MD5, SHA‑1, SHA‑256, and SHA‑512.

How hashing works

Paste text or drop a file; the tool streams bytes locally and outputs a hex digest. Compare it to published checksums to ensure files weren’t corrupted or tampered with. For large files, chunked processing keeps the browser responsive, and nothing is uploaded.

About the Hash Generator

Use SHA‑256 or stronger for integrity checks; avoid MD5/SHA‑1 for collision‑resistance. Never store user passwords with plain hashes—use bcrypt, scrypt, or Argon2 with salts and cost parameters.

Hashing is foundational for integrity, but not a substitute for encryption or authentication. Choose modern algorithms and verify end‑to‑end.
