SUMMARY
Microsoft Mail for PC Networks uses data encryption technology to provide security on many of the data files found in the postoffice database. Examples of the files that are encrypted are all .MAI, .ATT, .CAL, and .MMF files, as well as password fields in the MASTER.GLB and ACCESS.GLB files. Encrypting these files prevents anyone from dumping their contents and openly viewing the information contained in the file.



MORE INFORMATION
The data encryption algorithm employed by Microsoft Mail for PC Networks, while being proprietary, is NSA (National Security Agency) approved.

Microsoft Mails data encryption technique is similar to the Data Encryption Standard (DES) as designed by the National Bureau of Standards; however, unlike DES, the data encryption technology employed by Microsoft Mail is exportable outside the United States.
