What is a Hash and how to use it?
Cryptographic hash algorithms (like SHA-256) convert any amount of data into a unique, fixed-length string of characters. Our free tool allows you to quickly and securely generate hash values directly in your web browser, without sending any sensitive data to remote servers.
Frequently asked questions (FAQ)
What is the difference between encryption and hashing?
Unlike encryption, which can be decrypted back into the original text (using a key), hashing is a one-way process. Once a hash is created, it cannot be reversed. This is why hashing is used for securely storing passwords and verifying file integrity.
Are my data safe?
Absolutely. The tool utilizes the built-in Web Crypto API (crypto.subtle) on your device. The text you enter remains 100% local and is never stored or transmitted over the network.
