Encryption levels of Remote Desktop connections
There are four levels of encryption available for Remote Desktop connections:
Low Data sent from the client to the server is encrypted using 56-bit encryption. Data sent from the server to the client is not encrypted.
Client Compatible Encrypts client/server communication at the maximum key strength supported by the client. Use this level when the terminal server is running in an environment containing mixed or legacy clients. This is the default encryption level.
High Encrypts client/server communication using 128-bit encryption. Use this level when the clients accessing the terminal server also support 128-bit encryption. When encryption is set at this level, clients that do not support this level of encryption will not be able to connect.
FIPS Compliant All client/server communication is encrypted and decrypted with the Federal Information Processing Standards (FIPS) encryption algorithms. FIPS 140-1 (1994) and its successor, FIPS 140-2 (2001), describe U.S. government requirements for encryption.
