The invention provides a file encryption transmission method, device and equipment and a computer readable storage medium. The method comprises the steps: acquiring the transmission configuration information sent by the server, wherein the transmission configuration information comprises the encryption algorithm, the file segmentation number and the proportion number of the encrypted file blocks; segmenting the original text based on the file segmentation number; according to the proportion number of the encrypted file blocks, encrypting the partially segmented file blocks, and sending a transmission file with the plurality of encrypted file blocks and the remaining unencrypted file blocks to a server, so that the server decrypts the plurality of encrypted file blocks according to the transmission file and the obtained client public key, and sends the decrypted transmission file to the server. According to the invention, by encrypting part of the file blocks, the system resource consumption is reduced, the en
