Question 1

Is the Hash Generator free?

Accepted Answer

Yes, completely free with no account required.

Question 2

What hashing algorithms are supported?

Accepted Answer

The tool supports MD5, SHA-1, SHA-256, and SHA-512. All four hashes are computed and displayed simultaneously.

Question 3

Is my text sent to a server?

Accepted Answer

No. All hashing is performed locally in your browser using the built-in Web Crypto API and JavaScript. Your text never leaves your device.

Question 4

What is the difference between MD5 and SHA-256?

Accepted Answer

MD5 produces a 128-bit (32-character) hash and is fast but no longer considered cryptographically secure. SHA-256 produces a 256-bit (64-character) hash and is part of the SHA-2 family, which is secure for most purposes including checksums and digital signatures.

Question 5

Can I generate HMAC hashes?

Accepted Answer

Yes. Enter an HMAC secret key in the options panel and the tool will compute HMAC variants of each algorithm using your key.

Question 6

Is there a text length limit?

Accepted Answer

No. The tool can hash texts of any length, though very large inputs may take a moment to process.
