Rsearch of Mix Encryption Based on Software Security

This paper researches several famous data encryption algorithms and software encryption and realizes mix encryption technique using data encryption DES and RSA algorithm, machine fingerprint, key disk. The data encryption technique mixing with software encryption technique can enhance software security and secretion. The paper solved the difficult problem that software encryption security is low so far. The research has high values in theory and real application meaning, and provides a kind of security and cheap encryption software for all kinds of ware software.
