# ProofSnap

> Capture web pages as court-admissible digital evidence with blockchain timestamping, SHA-256 hashing, and digital signatures.

ProofSnap is a Chrome extension that turns any webpage into a tamper-evident evidence package. Each capture includes a full-page screenshot, page metadata, cryptographic hash (SHA-256), digital signature, and a Bitcoin blockchain timestamp via OpenTimestamps — all bundled into a verifiable ZIP archive with a complete chain of custody.

## Key Features

- SHA-256 cryptographic hashing of all evidence files
- Digital signature (RSA) with public key included for independent verification
- Bitcoin blockchain timestamping via OpenTimestamps (eIDAS 2 aligned)
- Forensic log (ISO/IEC 27037) with tamper-evident hash chain
- Chain of custody document with device integrity and NTP time verification
- Evidence PDF with all metadata compiled for legal proceedings
- DOM text extraction and full HTML preservation
- Trust Verifier for independent ZIP archive validation
- Available in 15 languages
