Abstract
The invention discloses a data transmission method and device, electronic equipment and a storage medium, and relates to the technical field of computer networks, and the main technical scheme comprises the steps: obtaining a symmetric key, carrying out the data encryption of a to-be-transmitted message according to the symmetric key and an XOR algorithm, and obtaining a message to be transmitted; the symmetric key is a key obtained by performing hash processing on key seeds preset by a receiving party and a sending party based on a preset algorithm; performing code conversion on the encrypted message to be transmitted by using a coding format corresponding to a transfer protocol compatible with displayable characters; and sending the message to be transmitted after code conversion to a receiving end. Compared with the prior art, according to the embodiment of the invention, the message to be transmitted is encrypted by using the XOR algorithm through the symmetric key, and the encrypted message is subjected to code conversion to ensure that the message meets the preset transmission standard, so that the data transmission security is effectively improved under the condition that the data compatibility is ensured; and illegal eavesdropping and tampering of the data in the transmission process are prevented.
