During the real machine test, I followed the online process and passed the test. At that time, I did not pay attention to the meaning of various certificates. Currently, message pushing requires various certificates and app id information. In order to better understand this process, I sorted out relevant information about certificates and so on. It is convenient for you and friends in need.

1. After OpenSSL is installed, find OpenSSL. CnF in the/usr/lib/SSL directory (for Ubuntu system, use whereis to check the SSL directory) and copy it to the working directory.
2. Create a New democafolder under the Work directory, create the new files index.txt and serial in the folder, and then create a newcerts folder. Add the character 01 to serial.

lower than that of symmetric encryption and decryption algorithms. Therefore, SSL uses asymmetric cryptographic algorithms to negotiate keys during the handshake process, and uses symmetric encryption and decryption methods to Encrypt transmission of HTTP content. The following is a metaphor for the image of this process (from http://blog.chinaunix.net/u2/82806/showart_1341720.html ):
Assume that a communicates with B, A is an SSL client, B is an SSL server, and encrypted messages are placed i
Digital Certificate and Its Application in Security Testing0x00 background
To perform security tests on the Web layer, it is inevitable that a man-in-the-middle proxy will be used to capture packets for analysis. Common tools include BurpSuit, Fiddker, and Charles. The usage of these tools has been described on the Internet. I will not go into details here. However, when testing websites with high security, you may encounter SSL communication problems

Introduction (Creating a generated certificate can only be used for test use.) If you want to use a self-signed certificate, you can only issue certificates to the CA authority for two-way authentication to use.
The use of HTTP (Hypertext Transfer) protocol to access data on the Internet is not encrypted. That is, anyone can intercept or listen to a stream of data that is transmitted over the network
Handshake and communication over the SSL protocol
To better understand and understand the SSL protocol, we will introduce the handshake protocol of the SSL protocol. SSL uses both public key encryption and symmetric encryption. Although symmetric encryption is faster than public key encryption, public key encryption provides better identity authentication. The SSL handshake protocol is very effective for customers and servers to complete identity authentication. The main process is as follows:①

The. PFX digital certificate is created automatically by using VS2005. The default validity period is only one year, and "Issuer", "issued to" is a combination of the current machine name and the current login username, in fact we can create a more friendly. PFX digital certificate.

One of the things faced by many network engineers is the maintenance and update of SSL certificates. For the author, SSL certificates are mainly used for VPN deployment, but there are also many network devices that need certificates to encrypt client-to-server communication. Every time I claim that I need a certificate, everyone will become speechless, and the certificate may be a bit scary for most people.
