Input Data
About Cryptographic Hashes
Digital Fingerprint
A hash function takes any input and produces a fixed-length string. Even a tiny change in input completely changes the output.
One-Way Process
Hashes are designed to be impossible to reverse. You can't retrieve the original data from a hash string, making it ideal for passwords.
Integrity Checks
Commonly used to verify that a downloaded file hasn't been corrupted or tampered with by comparing published hashes.
Frequently Asked Questions
Which hash algorithms are supported?
SHA-1, SHA-256, SHA-384 and SHA-512, all computed with your browser's native Web Crypto API. MD5 is intentionally not offered as it's cryptographically broken and unsupported by modern browser crypto.
What are hashes used for?
Verifying file integrity (comparing checksums after a download), deduplicating data, and fingerprinting content. A hash is one-way: you cannot recover the original data from it.
Is my text or file uploaded to compute the hash?
No. Hashing runs locally using the Web Crypto API built into your browser — your data never leaves your device.
