What Data Sig Does

Prove Your Data Is Real

Explains data signatures — hashes, digital signatures, and certificates — and how they prove a file or message is authentic and unaltered.

#️⃣

Hashes & Checksums

The fingerprint of a file — how one changed byte changes everything.

✍️

Digital Signatures

How private keys let you sign data so anyone can verify it came from you.

🏅

Certificates & Trust

Why your browser trusts a site: certificate chains explained without pain.

📄

Signing Documents

What legally and technically happens when you e-sign a contract.

⬇️

Verifying Downloads

Checking a published hash before you run that installer — step by step.

🚨

Spotting Tampering

How signature mismatches reveal altered files, forged emails, and bad actors.

How Data Sig Works

From signup to value in 3 steps

1

Fingerprint the Data

A hash condenses any file into a short string that changes if the file does.

2

Sign With a Key

Encrypting that fingerprint with a private key binds it to an identity.

3

Verify Anywhere

Anyone with the public key can confirm both the source and the integrity.

Frequently Asked

What is the difference between a hash and a signature?

A hash proves a file hasn't changed; a signature proves who it came from. A digital signature is essentially a hash encrypted with someone's private key.

Are e-signatures the same as digital signatures?

Not always. An e-signature can be a typed name; a digital signature is cryptographic proof. Many e-sign services layer one on top of the other.

Do I need special software to verify a file?

Usually not — modern operating systems include hash tools on the command line, and the site walks through the exact commands.
