What is Hashing?

A hash function takes input data and produces a fixed-size digest (fingerprint) that is practically impossible to reverse.

Even a tiny change in the input produces a completely different hash, making them ideal for integrity verification, password storage, and digital signatures.

For example: SHA-256("hello") = 2cf24dba...

Privacy & Security
  • 100% client-side — runs entirely in your browser via JavaScript
  • Zero network traffic — no API calls, no server requests, no data transmission
  • Nothing stored — input and output are never logged, recorded, or saved
  • Works offline — once the page loads, it functions without any internet connection
Common Use Cases

File integrity — verify downloads by comparing SHA-256 checksums.

Password hashing — generate bcrypt hashes for secure password storage.

Digital forensics — compute MD5/SHA hashes for evidence verification.

Data deduplication — quickly identify duplicate content using CRC or MD5.
