Encryption System Design Based on DES and SHA-1

For modern society, The concealment and completeness of data is particularly important. To solve this problem, developed a mixed DES and SHA-1 encryption system based on VC + + environment. The system on the one hand by Triple DES and RSA algorithms for data encryption to hide, on the other hand, by the SHA-1 algorithm to validate the integrity of data, it has a wide range of practicality.
