The Workplace applications use the AES (Rijndael) symmetric encryption algorithm with key size 128 bit in order to encrypt chat messages as well as all database queries (request & response). The chat encryption can be turned on or off from the Company Settings in the Administrator at any time. However, the database queries are always encrypted and you cannot turn it off.
Passwords are encrypted with SHA-512 and stored in the Savance Database
Workplace also supports HTTPS (SSL) communications, which adds another layer of encryption for all communications to and from the server to any of the clients including the browser, the application, the Outlook add-in, the kiosk, and all others.
