| Abstract: | The paper introduces several common encryption algorithms, and analyzes their advantages and disadvantages in network encryption. Digital envelope is a practical application of public-key crypto system, which may ensure the reliability of data encryption/decryption by calling the Microsoft CAPICOM component. The paper introduces an advanced method of using digital envelope method in secure communications, presents the flow and graphics, describes the preparation work and step-by-step procedure required for calling CAPICOM to realize secure communications using VB, and provides the detailed source codes. It provides a reference for a further understanding of the operation mode of CAPICOM as well as the engineering practice with respect to network security. |
