Hash Generator

Compute cryptographic hashes for any text or file. All four SHA algorithms run simultaneously so you can compare outputs side by side. Everything happens locally in your browser — nothing is sent to a server.

MD5 and SHA-1 are cryptographically broken and should not be used for security purposes. SHA-256 or SHA-512 are recommended for integrity checks.

How it works

This tool computes hashes directly in your browser using built-in security features. For text, it converts your input to its raw byte form before hashing. For files, it hashes the file contents directly.

SHA-256 and SHA-512 are the most widely used hashes for integrity verification, digital signatures, and password storage. SHA-1 is included for compatibility but is cryptographically broken — it should not be used for security-sensitive applications.

All computation runs entirely in your browser. No data is uploaded or stored. For large files, the hashing may take a moment — a loading indicator will appear while the file is being processed.
