Digital envelope encryption technology (algorithms combined with RSA and DES) This algorithm combines the advantages of DES and RSA. Principle: !. The sender uses the des key to encrypt important data. 2. the sender uses the RSA public key to encrypt the des key. 3. Send messages 4. After receiving the message, the receiver uses the RSA private key to decrypt the encrypted des key. 5. The receiver uses the RSA key to decrypt the decrypted des key to decrypt important data. In this article, we f

Configuring IPSec Encryption with a shared key in the Cisco PIX Firewall involves four key tasks: 1. Preparing for IPSec Preparing for IPSec involves determining detailed encryption policies, including determining the host and network we want to protect, and selecting an authentication method to determine detailed information about the IPSec peer, determine the IPSec features we need, and confirm that the existing access control list allows the IPSec data stream to pass; 1: determine an IKE (IKE

experience) so Java has a lot of libraries, but I started using go. I don't have a sixth sense, but I think Go should be the weakest in the list of supported protocols. The good news is that Go has a built-in Crypto/rsa software package, and the bad news is that it only supports pkcs#1. During the study, I discovered a third-party library that supported Pkcs#8, and we had to stop at the program point and focus on: 1. Using a well-tested library 2 bui
