Hash Generator

Generate MD5, SHA-1, SHA-256, SHA-512 hashes.

How to use

  1. Type or paste your input text in the box above
  2. The hash updates automatically as you type
  3. Choose the algorithm from the dropdown — output updates instantly
  4. Click Copy next to any hash to copy it to your clipboard

Which algorithm to use

  • SHA-256 — current standard for cryptographic use: file integrity, digital signatures, HMAC
  • SHA-512 — larger digest, faster on 64-bit hardware; higher security margin
  • SHA-1 — deprecated for security; still used by Git for commit identifiers
  • MD5 — broken for security; only use for non-security checksums and cache keys

Don't hash passwords with SHA-256

General-purpose hash functions are designed to be fast, which makes them poor for passwords. Use bcrypt, Argon2, or scrypt for password hashing — they're deliberately slow to resist brute-force attacks.
