Digital Signatures: Your Will Made Proof ​

What Exactly is a Digital Signature? ​

A digital signature is the unbreakable version of your handwritten signature. When you sign a paper, you trust that your handwriting will be recognized. When you sign digitally, mathematics guarantees it's you.

It's your way of saying "I accept, I commit, I stand by this" with cryptographic proof included.

Digital Signature vs. Electronic Signature ​

Electronic signature: Any digital scribble - from your finger on a tablet to a PIN. Legal value: "It depends"

Digital signature: Certificate issued by a licensed authority + cryptography + biometric verification. Legal value: Equal to your handwritten signature

The difference: One is an image, the other is mathematical proof.

Why It's Undeniable ​

🔐 Guaranteed Authenticity ​

It's not "looks like Juan signed." It's "Juan signed, the math proves it."

🛡️ Total Integrity ​

Change a comma in the document after it's signed and the signature automatically becomes invalid.

⏰ Exact Moment ​

Timestamp that certifies when you signed. Not a second's difference.

🚫 Non-Repudiation ​

You can't say "I didn't sign that." Your digital certificate gives you away.

How It Works (Simple) ​

  1. You are biometrically verified - Facial recognition + fingerprint vs. National Registry
  2. You receive your digital certificate - Your unique mathematical identity
  3. You sign the document - Your private key + the document = unique signature
  4. Anyone can verify - Instantly, from anywhere

Your Responsibilities ​

Basically: Don't share your private key.

It's like your house key - if you lend it, it's your problem.

  • Keep it secret
  • Use secure devices
  • If compromised, revoke it immediately

Law 25.506: Your digital signature is worth the same as your handwritten signature. Period.

There's no "it depends on the case" or "judicial evaluation." It's worth the same, period.

In summary: A digital signature is your will transformed into unbreakable mathematical proof. It's the closest thing to absolute certainty that exists in the digital world.
