Frequently asked questions
What is a cryptographic hash?
A cryptographic hash function takes an input (text or file) and produces a fixed-size string of bytes, typically displayed as a hexadecimal number. The same input always produces the same hash, but even a tiny change in input produces a completely different hash. Common uses include data integrity verification, password storage, and digital signatures.
Is this hash generator really free?
Yes, completely free. There are no hidden charges, no usage limits, and no premium features locked behind a paywall. Use it as much as you need.
Is my data secure?
Absolutely. All hashing happens entirely in your browser using the Web Crypto API. Your input data is never sent to any server, stored, or logged.
What's the difference between MD5, SHA-1, and SHA-256?
MD5 produces 128-bit hashes and is considered cryptographically broken for security purposes. SHA-1 produces 160-bit hashes and is also deprecated for security. SHA-256 (256-bit), SHA-384 (384-bit), and SHA-512 (512-bit) are part of the SHA-2 family and are currently considered secure for most applications.
Can I verify file checksums?
Yes! Upload a file using the file picker and the tool will compute its hash using all supported algorithms. You can then compare the computed hash against a known checksum to verify file integrity.
How do I compare hashes?
Use the Compare feature to enter a known hash value. The tool will show whether the computed hash matches your expected value, helping you verify data integrity at a glance.
Can I use uppercase hex output?
Yes! Toggle the Uppercase option to display hash values in uppercase hexadecimal format. This is useful when matching hashes displayed in uppercase by other tools.
Do I need to install anything?
No installation required. The hash generator works entirely in your web browser. Just open the page and start hashing.
Can I use this on my phone?
Yes, the tool is fully responsive and works on all devices — desktops, tablets, and smartphones.
