Digital signature is mainly used to send secure e-mail, access security site, online bidding and bidding, online contract, online ordering, secure online document transmission, online office, online payment, online tax and online shopping and other safe online electronic transactions.

First, SSL Overview The SSL protocol uses digital certificate and digital signature for two-terminal entity authentication, uses asymmetric encryption algorithm for key negotiation, encrypts data with symmetric encryption algorithm and transmits it to ensure the confidentiality of data, and verifies whether the data is tampered and forged in the transmission process by calculating the Digital digest. Thus,
The early SSLv2 was designed according to the classic PKI (public key Infrastructure), which by default assumed that a server (or an IP) would only provide a service, so at the time of the SSL handshake, the server side could be sure which certificate the client was requesting.However, it is not expected that the virtual host has developed vigorously, which resulted in an IP will correspond to multiple domain names. There are some solutions, such as a
SSL principle HTTP and HTTPS differences
HTTP default port is 80,https default port is 443;HTTP transmits data to plaintext, HTTPS transmits data is encrypted;
HTTP is the HTTP protocol that runs on top of TCP. All transmitted content is plaintext, the client and the server can not verify the identity of the other side;HTTPS is HTTP running over SSL/TLS, and

First, execute the following command on MySQL to query whether MySQL supports SSL:
Mysql> show VARIABLES like ' Have_ssl ';+---------------+-------+| variable_name | Value |+---------------+-------+| Have_ssl | YES |+---------------+-------+1 row in Set (0.02 sec)
When Have_ssl is YES, it means that the MySQL service already supports
SSL (Secure Sockets Layer, Secure Sockets Layer) is a security protocol that provides security and data integrity for network traffic. Developed by Netscape to secure data transmission over the Internet, data encryption (encryption) technology is used to make sure that information is not intercepted and tapped on the network.
SSL is currently supported by almost all browsers, but the supported versions are
