Encryption Configuration 
You use the Encryption Configuration screen to choose the encryption algorithm for encoding data servers, schedules, and credentials when you save in SAP Manufacturing Integration and Intelligence (SAP MII).
The available encryption algorithms are determined by your SAP NetWeaver instance and may include the following:
TripleDES is the default setting, which provides the strongest data encryption.
This method is based on Data Encryption Standard (DES), where the data are encrypted three times.
DES provides the second-strongest data encryption.
Base64 provides the least data encryption.
When no other encryption method is available, the system uses Base64 encoding.
Caution
Changing the encryption algorithm may cause disruptions to the system.
