Description:
Introduce automated encryption key rotation, where encryption keys are periodically rotated without user intervention, enhancing security by minimizing the risk of key compromise.

Benefits:

Enhanced Security: Reduces the risk associated with long-term use of a single encryption key.
Automated Management: Simplifies key management for users by automating the rotation process.
Use Case:
Encryption keys are automatically rotated at regular intervals, ensuring that email encryption remains secure and up-to-date without requiring user action.

These ideas aim to provide robust security measures to protect users' data and communications, enhance privacy, and ensure that Proton Mail remains a secure and reliable platform for managing sensitive information.
