Symfony 8.2 Adds Native PGP/MIME Support to Mailer Component

Symfony 8.2 adds native PGP/MIME support to the mailer component. You can now sign and encrypt outgoing emails directly inside the framework.

That means you can verify sender identities and protect message content from unauthorized access without relying on custom implementations or external libraries.

The implementation follows the PGP/MIME standard. It preserves the original email structure while running cryptographic operations. Dedicated classes handle the security protocols.

To set this up, you specify your keys and cryptographic settings in the mailer configuration files. After that, the framework automatically manages signing and encryption for outgoing messages that need these security measures.

Organizations can use this built-in capability to meet specific data privacy requirements when transmitting information over email.
