Server Access Security Using User ID and Password › Decryption of Common Format Buffer

Decryption of Common Format Buffer

The CFB data transmitted from DPC applications can optionally be encrypted. A flag byte in the CFB header signifies the data has been encrypted. This flag byte is used to notify the receiver of the CFB that it has been encrypted. It is the responsibility of the receiver to decrypt the CFB.

With respect to the Client Manager, the data in the CFB only needs to be decrypted if the security data located in the security offset is to be used when sending the cooperative flow request to a target server that has a derived security level of Remote.
