Hash Generator

Generate cryptographic hashes using the Web Crypto API

Input Text

All hashes are generated using the browser's native Web Crypto API. MD5 has been removed as it is cryptographically broken. Use SHA-256 or SHA-512 for security-sensitive applications.

Frequently Asked Questions

Is SHA-256 still secure?

Yes. SHA-256 is considered cryptographically secure with no known practical attacks. It is recommended by NIST and used in critical security applications.

Can the same input produce different hashes?

No. SHA-256 is deterministic — the same input always produces the exact same 64-character hex output.

What is the output length?

SHA-256 always produces a 256-bit (64 hexadecimal character) hash, regardless of input length.
