DEA Encryption


DEA is an file encryption utility based on 128-bit encryption (high strength encryption).

It operates as a Windows utility program.

This system uses a 16-character key which is much stronger protection than password-based systems.

Fast operation. Encrypts a 1-megabyte file in 3 seconds.

Windows does not include any encryption to protect files such as documents and spreadsheets.

Any data file that is sent outside your company should be encrypted to protect its privacy.

Developed by Blue Sky Technology in 2008, using a proprietary encryption algorithm incorporating byte-order scrambling for maximum protection.

Can be used to protect documents, spreadsheets, data files.
