The certificate contains a Collection Summary, Source Device details, a Conversations summary, and a Data Integrity section with the SHA-256 hash recorded at acquisition and verified again at upload, followed by a Certification statement and a QR code for verification. Four appendices follow: Chain of Custody (a timestamped log from extraction code creation to certificate generation), Data Integrity (the full hashes and match confirmation), Collection Method Statement, and Message Breakdown (per-conversation platform, message count, and date range).
