Question 1

How do I generate a hash with this tool?

Accepted Answer

Paste or type your text into the input, or pick a file, and the tool instantly computes the CRC32, MD5, SHA-1, SHA-256, SHA-384, and SHA-512 digests at once. You can then copy whichever digest you need.

Question 2

Can I hash a file instead of text?

Accepted Answer

Yes, choose a file and its bytes are read and hashed directly in your browser. The same six algorithms are computed, which is handy for verifying a download against a published checksum.

Question 3

Which algorithm should I use, and why is MD5 or SHA-1 still shown?

Accepted Answer

For security-sensitive uses such as integrity verification, prefer SHA-256 or higher, since MD5 and SHA-1 are considered cryptographically broken. MD5, SHA-1, and CRC32 remain useful for non-security checks like deduplication or quick file comparison, so they are included for compatibility.

Question 4

Is it free, and does it work offline without an account?

Accepted Answer

Yes, the Hash Generator is completely free with no account or sign-up. All hashing runs in your browser, so once the page is loaded it keeps working even without a network connection.

Question 5

Are my text or files uploaded anywhere?

Accepted Answer

No. Your text and file bytes are processed entirely on your device and never leave your browser, with no uploads, servers, or tracking involved.
