body (text, encrypted)
read_at (timestamp, nullable)
created_at (timestamp)
updated_at (timestamp)

Indexes:

• (sender_id, recipient_id) - For efficient conversation queries
• recipient_id - For unread message queries

API Endpoints

5. DELETE /api/messages/{messageId} - Delete a message
6. GET /api/messages/users - Get list of users to message
7. GET /api/messages/unread-count - Get unread message count

Models and Relationships

Message Model:

• sender() - BelongsTo User
• recipient() - BelongsTo User
• scopeBetween() - Query messages between two users
• scopeUnread() - Query unread messages
• markAsRead() - Mark message as read
• isRead() - Check if message is read

User Model (extended):

• sentMessages() - HasMany Message (as sender)
• receivedMessages() - HasMany Message (as recipient)

Security Measures

1. Encryption:

   • Messages encrypted with Crypt::encryptString() before storage
   • Decrypted with Crypt::decryptString() when retrieved
