About Hash Functions

Cryptographic hash functions are one-way functions that convert input data into a fixed-size string of characters. They are deterministic (same input always produces same output) and practically impossible to reverse.

Supported Algorithms

SHA-1: 160-bit (40 hex chars) - Legacy, not recommended for security
SHA-256: 256-bit (64 hex chars) - Standard for most applications
SHA-384: 384-bit (96 hex chars) - Higher security variant
SHA-512: 512-bit (128 hex chars) - Maximum security

Common Uses

  • Verify file integrity after downloads
  • Check if files have been modified
  • Generate unique identifiers from content
  • Store password hashes (with proper salting)
  • Digital signatures and certificates

Frequently Asked Questions

What is a hash?

A hash is a fixed-size string generated from input data using a cryptographic function. It's used to verify data integrity - even a tiny change in the input produces a completely different hash.

Which hash algorithm should I use?

SHA-256 is recommended for most purposes. SHA-1 is considered weak for security applications. SHA-384 and SHA-512 provide extra security for sensitive applications.

Can I hash files?

Yes! Use the File Input tab to select a file. The file is processed entirely in your browser - nothing is uploaded to any server.

Is this hash generator free?

Yes, WKIT Hash Generator is completely free. No signup required, no hidden fees.
