Hash Generator
Generate cryptographic hashes from any text.
Runs entirely in your browser — your data is never uploaded to any server.
How it works
- Enter your textAny length, any language.
- Pick an algorithmOr generate all of them at once.
- Copy the hashCompare it against a published checksum.
What this tool does
- MD5, SHA-1, SHA-256, SHA-384 and SHA-512
- Generate every algorithm in one pass for comparison
- SHA family computed with the browser Web Crypto API
- Input never leaves your device
Frequently Asked Questions
SHA-256 for anything new. MD5 and SHA-1 are included because you will still meet them in legacy checksums, but both are broken for security purposes.
Not by design. However, common inputs like short passwords can be found by brute force, which is why password storage needs a slow, salted algorithm instead.
It is fast and still fine as a non-security checksum for detecting accidental corruption. It must not be used where an attacker is involved.
This tool hashes text input. File checksums require reading the raw bytes.
Privacy and security
Your input is processed by JavaScript running inside your browser. Nothing you paste is sent over the network, logged, or stored — which is what makes this safe to use with production data. If you want to check this yourself: open your browser’s developer tools, switch to the Network tab, and use the tool — you will see no request carrying your file or input leave the page.
