Can a digital signature be trusted?

Real doubts, real concerns

‍

Someone sends you a PDF and says, “Just sign it digitally.” But what does that even mean? Is it safe? Can you prove it later?

‍

These are valid concerns. Many professionals still avoid eSignatures simply because they don’t fully understand how they work.

‍

‍

‍

Cryptographic integrity

‍

There’s a big difference between typing your name and creating a true digital signature. The real thing generates a unique cryptographic fingerprint of the file — and ties it to your identity.

‍

If the file changes, the signature breaks. That’s digital signature verification — no guessing, no assumptions.

‍

‍

Embedded metadata

‍

Most people don’t realize this, but a visually signed PDF offers no real protection. A real digital signature embeds metadata — timestamp, signer, device info, file version — into the file.

‍

This makes it tamper-evident and legally verifiable under eIDAS (EU) and ESIGN/UETA (US).

‍

‍

‍

Verified by protocol

‍

Systems like DocuChain use bank-level encryption, immutable audit trails, and verified identity protocols. That means you can create a digital signature that holds up in court, across borders, and over time.

‍

‍

Secure by default

‍

DocuChain lets you sign documents online securely — without apps or installs. Your digital signature is stored safely, reused when needed, and every signed file includes full validation data.

‍

Trust isn’t just earned — it’s encoded.

‍

Use digital signatures that prove what happened, not just what was intended.
