We have introduced the core implementation principles of mainstream double-layer encryption shells,At the same time, we mentioned compatibility and simplified the encryption Shell Core while considering the security.This article mainly discusses security and compatibility considerations. Security mainly deals with tw

Wireless networks are becoming more and more mature, but how can we enhance the security level? This requires us to understand the network security level. On the one hand, network security is ensured by encryption. The following describes common wireless network encryption m

IP Security encryption-IPSec uses network communication encryption technology. Although the header and tail information of a data packet cannot be encrypted, such as the source/destination IP address, port number, and CRC Check value, data packets can be encrypted. Because the encryption process occurs on the IP layer,
