SHA-256 (Secure Hash Algorithm 256-bit) is a member of the SHA-2 family designed by the NSA. It produces a fixed 256-bit (32-byte) hash, typically displayed as a 64-character hexadecimal string.

Yes. SHA-256 is widely considered secure and is used in TLS/SSL, Bitcoin, and many other security protocols. No practical collision attacks have been found.

How is this different from MD5?

SHA-256 produces a longer hash (256 bits vs 128 bits) and has no known vulnerabilities, while MD5 is considered broken for cryptographic purposes.

Is my data sent to a server?

No. The hash is computed locally using the browser's built-in Web Crypto API. Your text never leaves your device.
