Hash Generator
Choose Text or File mode, then generate MD5, SHA-1, SHA-256, and SHA-512 checksums instantly — free, private, and processed entirely in your browser.
About the Hash Generator
A cryptographic hash is a fixed-length fingerprint calculated from any input — text or a file — using a one-way algorithm. Hashes are used everywhere in software: verifying that a downloaded file wasn't corrupted or tampered with, storing passwords securely instead of as plain text, and confirming data integrity during security handshakes.
Our free online hash generator computes MD5, SHA-1, SHA-256, and SHA-512 checksums for any text or file entirely inside your browser. SHA hashes use the browser's native Web Crypto API, and everything runs locally — no data is sent to our servers.
How to Generate Cryptographic Hashes
Step 1
Select Text or File mode
Choose whether you want to hash typed text or an uploaded file.
Step 2
Input your data
Type or paste your text, or upload a file, then click "Generate Hashes".
Step 3
Copy your signatures
Copy any individual hash, or use "Copy All" to grab every checksum at once.
Frequently Asked Questions
What is a file checksum?
A unique cryptographic fingerprint of a file. If even a single byte of the file is modified, the hash changes completely. This is used to verify that downloads haven't been tampered with.
Are my files uploaded?
No, all hash computations occur client-side on your device. We do not upload your files.
Why is MD5 included if it's not secure?
MD5 is no longer considered cryptographically secure, but it's still widely used for quick file-integrity checks and matching legacy checksums.
Does it cost money?
No. The hash generator is 100% free to use, with no registration or account required.
