Problems solved by technology

Existing instant messaging products all use clear text transmission, and the transmitted information has no security protection, and is easy to be intercepted and tampered with; some instant messaging products use server-side encrypted messages, that is, messages will be encrypted when they pass through the server. Encryption to ensure that the message will not be stolen by a third party, but this information encryption method has a low security level, is easy to be cracked, has low practical value, and is prone to information leakage incidents

Abstract

The present application relates to an instant messaging method, device, electronic equipment and storage medium, characterized in that it includes: establishing a communication connection; sending a first public key; encrypting message content with a first private key to obtain first ciphertext information , the first ciphertext information is decrypted using the first public key; the ciphertext information is sent; and the first ciphertext information is stored locally, which can ensure the security in the communication process and simplify the process of encryption and decryption the complexity.

Description

technical field [0001] The present application relates to the application field of computer software, in particular to an instant messaging method, device, electronic equipment and storage medium. Background technique [0002] Instant Messaging (IM) refers to services that can instantly send and receive Internet information, including e-mail, short message, QQ, WeChat and other communication tools. Existing instant messaging products all use clear text transmission, and the transmitted information has no security protection, and is easy to be intercepted and tampered with; some instant messaging products use server-side encrypted messages, that is, messages will be encrypted when they pass through the server. Encryption ensures that the message will not be stolen by a third party, but this information encryption method has a low security level, is easy to be cracked, has low practical value, and is prone to information leakage incidents. Contents of the invention [0003]...
