Your signature used to mean something because it was hard to fake and easy to check. Then documents went digital, and a “signature” became a picture pasted into a PDF — easy to fake, impossible to check. TrustDID gives your name its weight back.
Seal it
One right-click when you issue the document. The seal is yours alone — tied to your identity at your own web domain.
Send it anywhere
A tiny companion file rides along — email, download, USB stick. The original is never modified.
Anyone can check it — free
Your customers pay nothing to verify. One click answers both questions:
That second line is what a pasted signature can never give you: not just intact, but vouched for — by a trust registry the receiver chooses to rely on. Your reputation, attached to every document that carries your name.
Signatures that verify forever
Here's the question nobody asks until it's too late: what happens to a signed contract in five years — after you've changed keys, changed providers, or moved on?
With most e-signature services, your proof lives exactly as long as your subscription. With TrustDID, every key you ever use is kept in a tamper-evident history. When someone verifies an old document, TrustDID finds the key that was valid on the day it was signed and checks against that. Rotate keys yearly, recover from a lost laptop, restructure the company — every signature you ever made keeps verifying.
Ready for the quantum era
Every seal carries two signatures: today's proven cryptography and a quantum-resistant signature standardized for the decades ahead. Documents you seal now stay provable in a world where yesterday's crypto doesn't. And because time matters as much as keys, provable time pins down when — with a timestamp nobody can rewind.
