# 7. Encrypt Mettings

This section describes the cryptographic design that powers Zoom Meetings. We offer two types of encryption for Meetings: enhanced encryption encrypts the meeting stream with a key which is available to the Zoom server infrastructure, allowing for features such as cloud recording and live captioning, as well as the opportunity to dial into a meeting from a mobile or landline phone. End-to-end encryption, on the other hand, ensures that only the clients of the participants who are in the meeting have access to the meeting key. This offers stronger security and privacy, but lacks all the features that require the server to be able to decrypt meeting contents.
