What is SSL (Secure Sockets layer)?
SSL or Secure Sockets Layer is a security protocol created by Netscape, which has become an international standard on the Internet to exchange sensitive information between the site and the computer that communicates with it, known as the client. The
SSL technology is built into all popular browsers and is automatically involved when the user connects to the web server that is with SSL support. It is easy to find out when the server uses SSL security, because the address in the URL window will begin https . “S” indicates a secure connection.
When your browser connects to the SSL server, the server automatically asks for an authority digital certificate (CA). This digital certificate positively verifies the identity of the server to ensure that you do not send sensitive data to the web hacker or fraudster. The browser also ensures that the domain name corresponds to the name on the Ca and that the CA has been generated by a trusted authority of anesthesia a valid digital signature. If all the soilIt goes well, you will not even be aware that this handshake took place.
However, if there is a CA defect, even if it is simply outdated, your browser will pop up a window to inform you of the exact problem he has encountered, allowing you to end the session or continue your own risk.
When you complete Handshake, your browser automatically encrypts all the information you send to the site before leaving the computer. The encrypted information is unreadable on the way. Once the information arrives on a secure server, it is decrypted using a secret key. If the server sends you back, this information is also encrypted at the end of the server before sending. Your browser automatically decrypt it on arrival and then displays it as it usually does.
For those who operate a secure server, it is also possible to check the client connected to the server to ensure that the person does not knowIt wipes that there is someone to whom a limited approach has been granted. Another feature of SSL technology is the ability to verify data so that the stoker cannot replace further transmission by actual transmission without detecting.
Although the SSL allows you to replace sensitive information online, it cannot ensure that the information will continue to be maintained secure as soon as it arrives safely on the server. To ensure that once sensitive information is received, you must read the Personal Data Protection Policy. It is little good to trust your personal data SSL, if people who eventually have them share it with third parties, or leave them on servers that are not bound by limited access and other security protocols. Therefore, it is always wise to read the Privacy Policy of any site that includes security measures, your personal data online before volunteering.
