Summary

With iChat, you can chat securely with other MobileMe subscribers. In a secure chat, all text, audio, video, or data transferred in the chat is encrypted. To use this safeguard, you and your chat buddy must both have MobileMe subscriptions and enable Secure Chat.

When both you and your chat buddy have MobileMe Secure iChat enabled and you start a chat, a lock icon appears in the upper-right corner of the iChat window. Text, audio and video are encrypted on your computer, sent across the Internet encrypted, and are not decrypted until they reach your buddy
