Abstract The invention discloses a network transparent encryption and decryption method, device and system, equipment and a storage medium. The method comprises the following steps: receiving an IP data packet from first equipment; extracting data content of TCP/UDP message data fields from the IP data packet, judging whether the data content is ciphertext data or plaintext data, and correspondingly processing to respectively obtain required type data; replacing the data content in the TCP/UDP message data field with the decrypted plaintext data or the encrypted ciphertext data to obtain a new TCP/UDP message data field; forming a new IP data packet together with an IP header field and a TCP/UDP message header field; and according to the IP address in the IP header field, sending the new IP data packet to a second device with the IP address. According to the invention, the confidentiality and integrity of data are guaranteed; network communication is efficient and transparent; the method is convenient and has no influ
