About Base64 & URL Encoder / Decoder & Security Considerations
Everything you need to know about how this utility processes data safely in your browser.
Is Base64 an encryption method?
No, Base64 is an encoding format designed to transmit binary data over text-only protocols. It provides zero cryptographic secrecy.
Why is SHA-256 preferred over MD5?
MD5 suffers from known hash collision vulnerabilities and is cryptographically broken, whereas SHA-256 is collision-resistant.
