Encryption

The administrator can configure Windows Communication Foundation (WCF) to encrypt messages along the way.

• Message encryption is ideal for connections made through the Internet without protection.

  • Not required if encryption is provided by the network connection (for example a Virtual Private Network (VPN)).

• Different algorithms are supplied by WCF.

  • The user can apply proprietary algorithms.

  • The default configuration is to use 128bit encryption.

  • Up to 256bit encryption is supplied.

    Note:
    Encryption can impact performance.

An example of encryption is illustrated later in section Message Level Security with Windows Authentication.
