Data Integrity

TODO: Write content for this page.

Protect data confidentiality and integrity in canisters. Cover VetKeys for onchain encryption (encrypt data so only authorized users can decrypt), identity-based encryption (IBE) patterns, X.509 certificate handling, signature verification for external data, and certified variable patterns for data authenticity. Include the encrypted-notes example as a real-world reference.
