Hash Generator
Generate MD5, SHA-1, SHA-256, and other hashes.
💡 About Hash Functions
- SHA-256: Industry standard, recommended for most use cases
- SHA-384/512: More secure, longer output, slower
- SHA-1: Deprecated for security, use only for legacy compatibility
- Hashing is one-way - you cannot reverse a hash to get the original text
- Same input always produces same hash (deterministic)
About Hash Generator
Hash Generator computes cryptographic hash digests of any text input using MD5, SHA-1, SHA-256, SHA-384, SHA-512, and other algorithms. Hashes are used to verify file integrity, store passwords (in combination with salting), generate fingerprints, and create content-addressed identifiers. All computation happens in your browser using the Web Crypto API.

Frequently Asked Questions
Is Hash Generator free?
Yes, completely free. No signup, no account, no usage limits. Use it as much as you need.
Is my data secure?
All processing happens directly in your browser using JavaScript. Your data is never sent to any server, stored, or shared. It stays entirely on your device.
Is MD5 safe to use for password hashing?
No. MD5 (and SHA-1) are too fast and have known vulnerabilities for this purpose. Use bcrypt, scrypt, or Argon2 for password storage.
Can I hash a file rather than just text?
Yes. You can upload a file and the tool will compute its hash, which is useful for verifying download integrity against a published checksum.
