Software Realization and Performance Testing of DES Cryptographic Algorithm on the .NET Platform

The software realization of DES symmetric encryption algorithm using CryptoAPI on .NET platform has been analyzed. The processing performance of the software implementation has been tested and it was shown, that the encryption rate is 11.1 Mb/sec on the Intel Celeron D 351 3.2 GHz processor, while the development environment is a flexible architecture independent tool and meets all the requirements to the secure implementation of cryptographic software.
