Encoding & Security Tools
Encoding and security tools convert text between Base64, URL-encoded and HTML-entity forms, produce MD5, SHA-1, SHA-256, SHA-512 and HMAC digests, generate cryptographically strong passwords and estimate how long a password would resist an offline attack. Hashing uses the browser Web Crypto API, so the values you type are never transmitted.

Encoding & Security Tools: frequently asked questions
Is it safe to hash a real password or secret here?
Hashing and HMAC signing use your browser's built-in Web Crypto API and never transmit the input. That said, as a general habit it is safer to hash test values rather than live production secrets in any web page.
Where do generated passwords come from?
They are produced with crypto.getRandomValues(), the browser's cryptographically secure random number generator. Passwords are generated locally and are never sent to or stored by Delimiter.live.
Is MD5 still safe to use?
No, not for security. MD5 and SHA-1 are broken for collision resistance and must not be used for passwords, signatures or integrity guarantees. They remain useful only for compatibility with legacy systems and non-security checksums, and the tools say so.
