Type of security used in email.cloud Data Proetection

Hi all,

I search for this information in the Web pages of Symantec, but I cann't find it. I need to know what type of encryption is used  under the Data Protection results, after the email was encrypted.

This information is necessary for compliance with the company.

What Algorithms are used AES-256, PGP, SHA-2?

What version of TLS is used, 1.2?

Regards,

Carlos
