Question 1

How do I verify a file?

Accepted Answer

Drop your file on this page. We calculate its checksum instantly. Click “Paste hash” and paste the expected value from the download page. The tool auto-detects the algorithm, shows match or mismatch, and highlights exactly where hashes diverge.

Question 2

What is a checksum?

Accepted Answer

A checksum is a unique code calculated from a file’s contents. Think of it as a fingerprint. Change even one byte in the file and the checksum changes completely. When two files have the same checksum, they’re identical.

Question 3

Why should I verify downloads?

Accepted Answer

Downloads can fail partway, get corrupted during transfer, or be tampered with by malicious software. Verifying the checksum confirms you received the exact file that was sent, with nothing missing or changed.

Question 4

What does “Verified package” mean?

Accepted Answer

When you drop a ZIP file from Digiwava, we check its checksum against our database. If it matches, you’ll see a green checkmark with the product details. If the seller has released a newer version since this file was downloaded, we note that too.

Question 5

What if the checksums don’t match?

Accepted Answer

Your file may be corrupted or modified. When you paste an expected hash, diverging characters are highlighted so you can see exactly where they differ. Delete the file and download again from the original source. If it still doesn’t match after a fresh download, contact whoever provided the file.

Question 6

Can I compare two files?

Accepted Answer

Yes. After dropping your first file, click “Compare file” and drop a second one. The tool calculates all four hashes for both files and shows a match or mismatch indicator for each algorithm. This tells you instantly whether the files are identical without needing an expected hash from someone else.

Question 7

Which algorithm should I use?

Accepted Answer

SHA-256 is the default and recommended for most files. It’s the modern standard used by software companies and security professionals. SHA-512 offers extra strength for sensitive files. MD5 and SHA-1 are older and included only for compatibility with legacy systems.

Question 8

Is my file uploaded anywhere?

Accepted Answer

No. Your file stays on your device and all calculations happen in your browser. For ZIP files, the computed checksum is sent to Digiwava to check for a matching product (see “Verified package” above). When you close the tab, nothing remains.

Question 9

Can two different files have the same checksum?

Accepted Answer

Theoretically possible, practically impossible. SHA-256 produces more unique values than there are atoms in the observable universe. The odds of two different files producing the same checksum by chance are effectively zero.
