What is a Hash?

A cryptographic hash function takes input data and produces a fixed-size output (the hash). The same input always produces the same hash, but even a tiny change in input produces a completely different hash.

Hash Algorithms

  • SHA-256 - 256-bit hash, widely used and secure
  • SHA-1 - 160-bit hash, deprecated for security purposes
  • SHA-512 - 512-bit hash, more secure than SHA-256

Use Cases

  • File integrity verification
  • Password storage (with salt)
  • Digital signatures
  • Data deduplication

Keyboard Shortcuts

  • Ctrl + S - Download all hashes
  • Escape - Clear all inputs
  • Tab - Insert 2 spaces in input
