Hash Generator

Generate cryptographic hashes using MD5, SHA-1, SHA-256, SHA-384, and SHA-512 algorithms

Input Data
Enter text or upload a file to generate hashes
Hash Algorithm Information

🔒 Secure Algorithms:

  • SHA-256: Most commonly used, very secure
  • SHA-384: Higher security, larger hash
  • SHA-512: Highest security, largest hash
  • • Use these for password hashing and security

⚠️ Legacy Algorithms:

  • MD5: Fast but cryptographically broken
  • SHA-1: Deprecated, vulnerable to attacks
  • • Use only for checksums, not security
  • • Consider upgrading to SHA-256 or higher

About this tool

The hash generator computes MD5, SHA-1, SHA-256 and SHA-512 hashes of any text, in the browser, with nothing sent to a server. Type or paste content and each algorithm's digest appears immediately.

A hash is a fixed length fingerprint of data: the same input always yields the same hash, while any tiny change produces a completely different one. That property powers file integrity checks, digital signatures, blockchain and password storage.

Common uses
  • Verify a downloaded file matches the publisher's checksum
  • Generate cache keys and deduplication fingerprints
  • Compare two texts for equality without reading them
  • Learn how hash functions behave with different inputs
Tips
  • Use SHA-256 or stronger for anything security related. MD5 and SHA-1 are broken for that purpose
  • Hashing is one way. Unlike encryption, there is no key to reverse it
  • Real password storage needs slow, salted algorithms like bcrypt or Argon2, not plain fast hashes
Frequently asked questions
What is the difference between MD5, SHA-1 and SHA-256?+

They differ in output length and security. MD5 produces 128 bits and SHA-1 160 bits, and both have known collision attacks. SHA-256 produces 256 bits and remains secure, making it the default choice today.

Can a hash be decrypted back to the original?+

No. Hashing is one directional by design. Attackers can only guess inputs and compare hashes, which is why long random inputs are effectively impossible to recover.

Why do MD5 hashes still appear on download pages?+

For accidental corruption checks MD5 still works and is fast. It only fails against deliberate tampering, so security conscious publishers list SHA-256 instead.

Is text I hash here kept anywhere?+

No. Hashes are computed locally in your browser using the Web Crypto API and your input is never transmitted.
