Frequently asked questions
Why is MD5 not included?
MD5 is considered insecure and is not provided by the browser’s crypto API. SHA-256 is the recommended modern choice.
Can a hash be decrypted?
No. Hashing is one-way, so a hash cannot be turned back into the original text.
Is it free?
Yes. All tools are free, with no sign-up and no limits.
Is my text uploaded?
No. Everything runs locally in your browser, so your text stays private.
Does it work on mobile?
Yes. It works in any modern mobile or desktop browser.
