@mofejo1 has applied to work on this issue as part of the Stellar Wave Program's 5th wave.

Hello, I would like to apply for issue #178 (Transaction Template Cloud Sync - Encrypted Export).

I have experience with frontend encryption, IndexedDB, and React component work. Here is my plan:

• Use encryption.js to derive a key from a user-supplied password (PBKDF2 + AES-GCM) and serialize the full template pack into an encrypted export blob
• Add export and import UI to TemplateLibrary.jsx with a password prompt and file picker
• Ensure nothing sensitive is written to IndexedDB in plaintext - encrypted blobs only
• Wire template actions into the command palette via KeyboardNavigation.jsx
• Update docs/api/encryption.md to document the export format and key derivation scheme

No one has applied yet and I can start right away. Can I get this assigned?

Thanks
