Why TrustLog?

            

                
Cryptographic Tamper-Proof Verification

                
Each log is secured with SHA-256 hashing, creating an immutable cryptographic fingerprint. Any modification to the log data will immediately produce a different hash, providing irrefutable proof of tampering.

            

            

                
Immutable UTC Timestamp

                
Every verification includes a precise UTC timestamp that cannot be altered. This creates a permanent record of when the log was verified, essential for audit trails and compliance documentation.

            

            

                
Decentralized Verification

                
No central server or database required. Verification happens entirely in the browser, ensuring your data never leaves your control and verification is always available offline.

            

            

                
Public Verification Links

                
Generate permanent verification URLs that allow anyone to independently verify log integrity without needing special tools or access credentials.

Credibility Advantages

            

                
Independent Verification

                
Any third party can independently verify the integrity of your logs using standard cryptographic tools, eliminating reliance on trusted intermediaries.

            

            

                
Zero Trust Architecture

                
No backend infrastructure means no single point of failure or compromise. Verification happens locally, ensuring maximum security.

            

            

                
Permanent Proof

                
Downloadable HTML files contain all verification data embedded, creating permanent, self-contained proof documents.

            

            

                
Open Standards

                
Uses industry-standard SHA-256 hashing algorithm and ISO 8601 timestamp format, ensuring compatibility with existing verification tools.

            

        


        

            
Frequently Asked Questions

            

                
What makes TrustLog tamper-proof?

                
TrustLog uses SHA-256 cryptographic hashing to create an immutable fingerprint of your log data. Any modification to the original JSON will result in a completely different hash, making tampering immediately detectable. The hash is computed locally in your browser, ensuring no external entity can alter the verification process.

            

            

                
How does verification work without a backend?

                
TrustLog is entirely client-side. All cryptographic operations happen in your browser. The verification link contains the unique ID in the URL hash, and all verification data is embedded directly in the downloadable HTML file. Anyone can verify integrity by recalculating the SHA-256 hash of the raw JSON content.

            

            

                
Can I share my verified logs publicly?

                
Yes, the verification link and downloaded HTML file are designed for public sharing. They contain all necessary metadata for independent verification without requiring access to any private servers or authentication.

            

            

                
What is the Agent Readable Port?

                
The Agent Readable Port provides structured JSON output that AI agents and automated systems can easily parse and process. This enables seamless machine-to-machine interaction and automated verification workflows for enterprise integration.

            

            

                
Is TrustLog suitable for compliance audits?

                
Absolutely. TrustLog provides cryptographic proof of integrity and immutable timestamps that meet the requirements of most regulatory frameworks including GDPR, HIPAA, and SOC 2. The downloadable HTML files serve as permanent audit records.

            

            

                
How secure is the verification process?

                
TrustLog uses the SHA-256 cryptographic hash function, which is widely recognized as secure and collision-resistant. All operations occur locally in your browser, so your data never leaves your device during verification.
