DES3 Development Kit is a set of DLLs for integrating cryptography into your application. The cryptographic algorithm employed is the Data Encryption Standard (DES). DES3 offers a simple-to-use "C"-language API for accessing the cryptographic routines. The routines have been written in assembly language for fast performance, and they are fully reentrant at the process and thread level. Support is provided triple-DES encryption and for ECB and CBC modes.
