Prudent use of cryptology methods and types:
Personally identifiable information such as Social Security Numbers will be encrypted using only a Microsoft encoding technique specified in the .NET Framework. For example, a .NET Team Leadership Committee could specify that all public key (symmetric) encryption will be used in all web applications utilizing the 3DES type of encoding. The Leadership Committee will designate where the public encryption key will be kept, and assign access to this key.
Symmetric key information will be encrypted in the abstract base class BLL file (BLL.cs) if used. See "Sensitive Data" for more information.
