Zoom rolls out end-to-end encryption (E2EE) for free and paid Zoom users starting from next week. In the end-to-end encryption meeting, up to 200 participants can join.
Zoom initially announced plans for the end-to-end-encrypted meeting earlier in May, it let all users generate public cryptographic identities to establish trust relationships between meeting attendees.

Starting from next week Zoom’s E2EE will be available as a technical preview for the first 30 days to get feedback from users.
Zoom end-to-end encrypted meetings will not support phone bridges, cloud recording, or non-zoom conference room systems.
With the Zoom’s E2EE GCM(Galois/Counter Mode) encryption is used, as it is suitable for video conferencing. GCM is a stream cipher, rather than a block cipher.
While hosting a meeting the host generates encryption keys and uses public-key cryptography to distribute these keys to the other meeting participants.
Zoom servers act only as a relay and they unable to fetch the encryption keys required to decrypt the meeting contents.
End-to-end encryption is another stride toward making Zoom the most secure communications platform in the world,” said Zoom CEO Eric S. Yuan.
To use now, customers should enable Zoom’s E2EE from the account level
For now with the current version Enabling the Zoom’s E2EE in your meetings disables certain features, including joining before host, cloud recording, streaming, live transcription, Breakout Rooms, polling, 1:1 private chat, and meeting reactions.
If you are using end-to-end-encryption participants can look for a green shield logo in the upper left corner of their meeting screen with a padlock in the middle to indicate their meeting is using E2EE.
