Many people ask me how to implement IPSec VPN technology, and I've done a case to show you how to configure a router-based IPSec VPN.
Due to work needs, the company's Nanjing office and the Shanghai office to establish a VPN connection. Nanjing Office Network settings: Intranet IP 10.1.1.0/24, extranet IP 202.102.1.5/24, Shanghai office network settings: Intranet IP 10.1.2.0/24, external network IP 202.102.1.6/24.
The following configuration steps are performed on both sides of the router:
I.
Two physical hosts are used to simulate the company and home network respectively. Both physical hosts are connected to a TP-link home Broadband Router to simulate the Internet environment. Two virtual NICs are bound to one vmwarevm respectively. The purpose is to achieve access between two vmwarevms through VPN.Company network topology650) this. width = 650; "src =" ../attachment/201209/215639928 .png" border = "0" alt = ""/>The company router configuration is as follows: Building configuration

GRE Over IPSec, as the name suggests, is to establish a GRE tunnel on the IPSec interface, while an IPSec Encryption mode is tunnel mode to encrypt the network segment to the network segment ), this is the GRE tunnel built on the IPSec encrypted CIDR block.

The following is an example of the Code for encryption and decryption in nodejs: {code...} How can php write the corresponding encryption and decryption code? It is required that the encrypted data such as Gpkr1WGBFhMvNdHr0eaBg can also be decrypted to nodejs. The following is an example of the Code for encryption and decryption of nodejs:

JAVA and. net des encryption and decryption
A project was created a few days ago, which requires DES encryption between the two systems. One system is developed for JAVA, and the other one is developed for. Net.
I found a lot of writing methods on the Internet, but the encrypted data cannot be matched between the two systems,
I can use it after making a small modification and have tested it.

The source code of OpenSSL consists of three parts: the encryption algorithm library, the SSL library, and applications.
The source code of the encryption algorithm library is mainly in the crypto folder, including the ASN.1 encoding and decoding interface (crypto/asn1/asn1.h) and the pseudo random number generator (crypto/rand. h), ENGINE mechanism (
