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 pr
Install let ' s Encrypt client For CentOS distributions There are currently two ways to install let's Encrypt clients, one of which is a direct yum installation from the upstream Epel source, one that is downloaded from the Encrypt source of let ' s GitHub.

SSL is a commonly used WEB Service encryption channel. Its full name is Secure Socket Layer, which is also known as the Secure sockets interface. It uses digital certificates to ensure its security mechanism. The main function is encryption and authentication to protect the security of network transmission. It is in the middle of the HTTP and TCP layers. SSL encryption and authentication use public keys and

Today colleagues do manage the project, the request interface returns the following error SSL certificate problem:unable to get local issuer Certificate.This issue occurs because the trusted server HTTPS authentication is not Configured. By default, Curl is set to not trust any cas, which means that it does not trust any server Authentication. therefore, This is why the browser cannot access your server ove

unsecured network to prevent hackers from eavesdropping and attacking. SSL (Secure Sockets Layer) can be used to encrypt the flow of data between the Web server and the client. SSL encrypts data using asymmetric cryptographic techniques. The encryption process uses two keys: a public key and a corresponding private key. Data encrypted with
encryption and decryption algorithm is much lower than that of symmetric plus decryption. Therefore, SSL in the handshake process using asymmetric cryptographic algorithm to negotiate the key, the actual use of symmetric encryption and decryption method to encrypt the transmission of HTTP content. Here is a metaphor for the image of the process (excerpt from http://blog.chinaunix.net/u2/82806/showart_1341720.html):Suppose a communicates with B, A is
Https is also an ssl certificate. We generally think that https is secure, but the credit chain system of the SSL certificate is not secure. In particular, man-in-the-middle attacks are equally feasible in some countries where you can control CA root certificates. In addition, when the

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.
