About Hash Generator

Compute cryptographic hashes from text input or files using MD5, SHA-1, SHA-256, SHA-384, or SHA-512. Choose multiple algorithms at once to compare outputs. Output in hex or base64 encoding. All computation happens locally using Web Crypto API — nothing is uploaded.

Features

  • Support for MD5, SHA-1, SHA-256, SHA-384, SHA-512
  • Hash text input or uploaded files
  • Hex and Base64 output encoding
  • Compute multiple algorithms simultaneously
  • Copy individual hash values
  • File hashing for integrity verification
  • 100% client-side — nothing is uploaded

How to use

  1. 1Enter text or select a file to hash.
  2. 2Choose which algorithms to compute.
  3. 3Select hex or base64 encoding.
  4. 4Click Hash to compute all selected digests.

Frequently Asked Questions

Is MD5 secure?
MD5 is cryptographically broken and should not be used for security. It's still useful for non-security checksums and legacy compatibility.
Which algorithm should I use?
SHA-256 is the recommended default for most use cases. SHA-512 offers higher security margins. Use SHA-384 if required by a specific protocol.
Can I hash large files?
Yes. Files are read entirely into memory, so very large files (multiple GB) may be slow or hit browser memory limits.
Is my data sent to a server?
No. All hashing runs locally in your browser via the Web Crypto API and a client-side MD5 implementation.
