Method and system for encrypting and deciphering E-mail

Abstract

The invention is applied to the communication safety field, providing an E-mail encrypting and decrypting method and system, and the method comprises the steps of: receiving input encryption cipher information and selected folder information in mainbox; adopting encryption algorithm to generate encryption cipher according to the encryption cipher information and encrypting the selected folder in mailbox. Thus, the method provides secondary cipher protection for E-mail in encrypted folder, and assures E-mail security, and especially provides full safety assurance for users' important and private data.

Description

technical field [0001] The invention belongs to the field of communication security, in particular to an email encryption and decryption method and system. Background technique [0002] Nowadays, with the development and popularization of the network, email (Email) has become an important communication tool, and its security has been paid more and more attention. [0003] At present, the security of e-mail is guaranteed by the login password of the mailbox. The e-mail is stored on the mail server in the form of plain text (unencrypted).
