Hash Generator
Generate MD5, SHA-1, SHA-256 and SHA-512 hashes using the Web Crypto API. Your input never leaves your browser.
Privacy: This tool runs entirely in your browser. Your data never leaves your device and is never uploaded to any server.
Hashes are computed live in your browser using the Web Crypto API (and a local MD5 implementation).
Frequently asked questions
What is a hash function?
A hash function maps arbitrary input to a fixed-size string of characters. The same input always produces the same hash.
Is MD5 secure?
MD5 is considered cryptographically broken and should not be used for security. Use SHA-256 or SHA-512 for cryptographic purposes.
Is my input sent to a server?
No. Hashing runs locally in your browser using the Web Crypto API and a local MD5 implementation.
