fix(daemon): base64 encode encrypted track data for JSON transport#139
Conversation
Raw binary ciphertext was being stored as strings and JSON-serialized, causing data corruption due to invalid UTF-8 sequences. This fix adds base64 encoding for the Encrypted, AesKey, and Nonce fields before sending to the server. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Summary of ChangesHello @AnnatarHe, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request provides a crucial fix for the daemon's track API, specifically addressing data corruption that occurred when encrypted information was transmitted using JSON. The core problem stemmed from binary ciphertext being improperly serialized as strings, leading to invalid UTF-8 characters. By introducing base64 encoding for the encrypted payload, AES key, and nonce, the changes ensure that binary data is safely converted to a text-based format suitable for JSON transport, thereby preventing data loss and enabling the reliable operation of encrypted tracking.

Code Review
This pull request correctly addresses a data corruption issue by base64-encoding encrypted binary data before JSON serialization. The changes are correct and effectively fix the bug. While reviewing, I noticed that some error handling paths in the surrounding encryption logic could be improved to prevent potential panics or sending invalid data. Since those are outside the scope of this PR's changes, I recommend addressing them in a follow-up to enhance the overall robustness of the feature.
