Since

1.3.0

4.0.0 Refactored to use decorator_writer_base

This file provides an encrypted_writer class that wraps any existing log_writer_interface and encrypts log data before writing. Essential for compliance with GDPR, HIPAA, PCI DSS, and SOC 2 regulations.

Security features:

• AES-256-GCM authenticated encryption
• Unique IV per log entry
• Secure key management via secure_key_storage
• Key rotation support
• RAII-based key cleanup
