We must now define a global encryption policy, which will be used to define the encryption algorithms. There are two encryption algorithms: 56-bit DES and 40-bit DES, which can be used when configuring per-session encryption policies.

By default, 56-bit DES is used. Both have two possible modes: 8-bit CFB and 64-bit CFB; but 64-bit CFB is the default in each mode due to its superior performance.
