Frequently Asked Questions
What is a hash used for?
A hash is a fixed-length fingerprint of your text. It's commonly used to verify that a file or message hasn't been altered, or to check that two pieces of text are identical without comparing them directly.
Is the hash generated on a server?
No. This tool uses your browser's built-in Web Crypto API to compute the hash locally — your text is never sent anywhere.
Which algorithm should I use?
SHA-256 is the most common general-purpose choice today. SHA-1 is considered weak for security purposes but is still used for basic checksums; SHA-384 and SHA-512 offer a larger output for extra collision resistance.
