Technology

1. Overview

This page summarizes the technology behind Legitly™ — how our authentication works, the security that protects it, and the tools that sit on top of it. For the platform reference, see our Documentation; this page is subject to our Terms of Service.

2. 100% Single-Use Authentication

Every Legitly security code is designed to be 100% single use. A genuine code registers as used on its first valid scan and cannot legitimately be re-scanned or reused — which is what makes duplication detectable and counterfeiting hard.

3. SHA-256 — Military-Grade Encryption

Our codes and verifiable documents are protected with SHA-256, a military-grade cryptographic standard. It produces a unique fingerprint that underpins the integrity and verifiability of what we issue.

4. Single or Infinite Scan

Brands can choose how a code behaves: single scan, where the code is consumed after one verification, or infinite scan, where customers can verify the same item repeatedly. You select the model that fits your product and anti-counterfeiting strategy.

5. Code and Sticker Tracking

You can track our security codes and stickers — following scans and activity so you have visibility into where and how your products are being verified.

6. Tamper-Evident Holographic Stickers

Our holographic stickers are tamper-evident, designed to show evidence if someone tries to remove or transfer them, so a genuine label stays tied to the genuine product it was issued for.

7. Zero Counterfeit — Check the URL

There is zero chance of counterfeit when customers verify through the correct address. The trust anchor is the URL: genuine verification happens on legitly.com. If a scan or link sends a customer somewhere else, that is the red flag.

8. The Legitly Tools

Built on this foundation are our tools, each with its own info page: QR Generator, Voice (speech-to-text and court-ready transcripts), Video Checker (C2PA Content Credentials), Encrypted Messages (single-use, self-destructing), Ancient Text (community decoding archive), and our G-Codes generator.
