MigChat CLI v0.2.1 - Message Decryption Fix

This is a patch release that fixes a critical bug where encrypted messages were not being decrypted when viewing conversations.

🐛 Bug Fix

Fixed: Messages Showing as Encrypted Base64

Issue: When viewing conversations, messages were displaying as encrypted base64 text instead of decrypted plaintext.

Root Cause: The current_password was None when viewing conversations if the user was already logged in from a previous session. The password is only captured during login or account creation, not when starting an already-logged-in session.

Impact: Users couldn't read their encrypted messages - they would only see the raw base64 ciphertext like:

Solution

  • Added ensure_password() method that prompts for password when needed for decryption
  • Updated print_message() to use ensure_password() instead of assuming password exists
  • Better error handling to show specific decryption failures
  • Backward compatibility maintained for unencrypted messages

🔧 How It Works Now

  1. When you view a conversation with encrypted messages
  2. If password isn't cached, you'll be prompted once to enter it
  3. Password is cached for the session
  4. All subsequent messages decrypt automatically
  5. If decryption fails, you see a clear error message instead of raw base64
