How It Works

Privacy First

This hash generator (md5, sha-1, sha-256) processes your data entirely in your browser. No data is uploaded to any server, ensuring complete privacy and security.

Lightning Fast

Instant processing with real-time validation and error detection. No waiting, no delays - just immediate results.

Versatile Use Cases

  • Verify file integrity and detect tampering
  • Generate password hashes for storage
  • Create checksums for data validation

Mobile Friendly

Responsive design that works perfectly on all devices and screen sizes. Touch-friendly interface for mobile users.

Frequently Asked Questions

Which hash algorithm should I use?
For new applications, use SHA-256 or higher. MD5 and SHA-1 are deprecated for security use but still useful for checksums and non-cryptographic purposes.
Is MD5 secure for passwords?
No, MD5 is cryptographically broken and should never be used for passwords. Use bcrypt, scrypt, or Argon2 for password hashing instead.
What's the difference between hex and Base64 output?
Hex uses 0-9 and A-F characters (longer), while Base64 uses A-Z, a-z, 0-9, +, / (shorter). Both represent the same hash data in different formats.
Can I reverse a hash to get the original data?
No, cryptographic hashes are one-way functions. You cannot reverse them to get the original data, but you can verify if input matches by comparing hashes.
Why do I get different hashes for the same text?
Make sure you're using the same algorithm and text encoding. Different algorithms or character encodings will produce different hashes.
