Post-quantum cryptography, SHA-256 hashing, the ICP-Brasil timestamp, and immutable storage work in layers. Each one closes a gap that common tools leave open.
The capture application is open source. Any forensic expert can audit the algorithm and confirm that the evidence leaves your computer exactly as it appears on screen.
Every certificate carries a public verification code. Courts and experts check authenticity directly on Lexato, without having to trust our word.
Post-quantum cryptography, SHA-256 hashing, the ICP-Brasil timestamp, and immutable storage work in layers. Each one closes a gap that common tools leave open.
The capture runs locally on your computer, with an isolated session and automatic certificate generation. Ready to start in a few minutes.
Technical layers of protection that sustain the authenticity and forensic integrity of each piece of evidence.
Unique digital fingerprint of the captured content. Any change, however small, produces a different hash — making any loss of integrity evident.
Timestamp issued by a Certifying Authority accredited by ITI, with legal validity recognized throughout Brazil under RFC 3161.
Hash anchored on three public blockchains (Polygon, Arbitrum, Optimism). The record is decentralized and remains accessible even without Lexato.
Original URL, source IP, User-Agent, screen resolution and other technical data are preserved alongside the capture, supporting the chain of custody.
Detailed document with all technical information about the capture, digitally signed and structured for presentation in legal proceedings.

Hi! I saw your Honda Civic 2020 ad. You're selling for R$85,000, right?
That's right! Very well maintained car, single owner.
Looks great! But I need to know: has it ever been in an accident or had any issues? It's very important to me.
Não, nunca teve nenhum problema. Carro em perfeito estado, só uso para trabalho.
Perfect! I'll make the transfer and pick it up tomorrow. Thanks!
