Hybrid encryption method for instant messaging

The invention relates to a hybrid encryption method for instant messaging. The method comprises the steps that: (1), a client side obtains an asymmetric encryption public key, and simultaneously, randomly generates a symmetrical encryption key; (2), the client side sends a login request to a server side; the login request includes the symmetrical encryption key randomly generated by the client side; and the login request is subjected to asymmetric encryption through the asymmetric encryption public key, and then, sent to a server; (3), the server side obtains the symmetrical encryption key sent by the client side after receiving the login request and completing login; and (4), after login is completed, all interaction requests between the client side and the server side are symmetrically encrypted by adoption of the symmetrical encryption key. Compared with the prior art, the hybrid encryption method disclosed by the invention has the advantages of being high in security, communicationefficiency and flexibility and the like.
