1. PrefaceIn order to improve the security level of Remote Desktop, ensure that data is not stolen by xxx, in Windows2003 's latest patch package SP1 added a secure authentication method of Remote Desktop features. With this feature we can use SSL encryption information to transfer control of remote server data, so as to compensate for the remote Desktop functionality of the original security flaws.2, probl

1. Will the SSL Certificate affect the speed and traffic? Encryption and decryption for each SSL connection will increase the processing workload of the server CPU. Considering the protection of customer privacy and security, according to relevant surveys, deploying SSL certificates of well-known brands on importan

trustworthy.(2) Public key encryption calculation is too large, how to reduce the elapsed time?WORKAROUND: Every session, the client and server generate a "conversation key" (Session key), which is used to encrypt the information. Because the "conversation key" is a symmetric encryption algorithm, the operation speed is very fast, and the server public key is only used to encrypt the "conversation key" itself, which reduces the time spent on cryptographic operations. (That is, the encryption of

message to identify that the server-side handshake has been completed.10. the SSL handshake ends successfully. The client and server start to use the session key to encrypt and decrypt all data exchanged between the two parties.Is a common SSL handshake process: In the process of using a digital certificate for identity authentication, the server-side authentication is slightly different from the client.

CA's information and public key, both client and server. 1. The client initiates a connection request to the MySQL server, both parties negotiate the encryption algorithm, SSL version, etc. 2. The server sends its own certificate (SSL-CERT.PEM content, CA signed) to the client, and the client decrypts it with SSL-CA.P

InternetHypertext Transfer Protocol(HTTP) uses SSL for secure communication. The data transmitted between the client and the server is symmetricAlgorithm(Such as des or RC4.

Currently, many websites or services are implemented based on SSL and can be accessed only after certificates are downloaded and installed. If it can provide download, of course there are any problems. However, if you do not have permission to download and it is not a CA certificate, it is only a self-Signed server certificate. Only know its port and address. If you forcibly access it through a program, you may get the following error: javax.net.ssl.

First, you need to understand some basic concepts before installing 1. Certificates used by SSL can be self-generated or signed by a commercial ca such as Verisign or thawte. 2. Certificate concept: First, you must have a root certificate, and then use the root certificate to issue the server certificate and customer certificate. Generally, the server certificate and customer certificate are in a hierar

How to configure multiple SSL certificates for a single Nginx IP addressBy default, an Nginx IP address only supports one SSL certificate. You need multiple IP addresses to configure multiple SSL certificates. If the public IP address is limited, you can use the TLS Server Name Indication extension (SNI, RFC 6066), which allows the browser to send the server name
