What is SSL?Originally developed by the Netscape Enterprise, the Secure Socket Layer (SSL) protocol is now a global standard for authenticating Web sites and web browser identities, and for encrypting communications between users of browsers and Web servers. Because SSL technology is built into all major browsers and Web server programs, you can only install digital certificates or server certificates to activate Server functionality.What is a server
HTTPS access to a Web site, server-side and client data transmission is encrypted, will not be intercepted, than the normal HTTP protocol more secure. Let me introduce the configuration of SSL under IIS6.0 to achieve HTTPS access. Detailed process screenshots are described.
1, enter the site properties, select Directory Security, and then click on the server certificate to configure the certificate:

"Digital Certificate" is mysterious (for newcomers ). In this way, people can stay away from each other. In fact, there is a lack of understanding. A digital ce
succeeds, it proves that Alice's private key is correct and thus completes Alice's identification. The authentication process is as follows:
Alice uses her private key to encrypt the file and sign the file.Alice transfers the signed file to Bob.Bob decrypts the file with Alice's public key to verify the signature.Alice uses her own private key for encryption, and Bob uses Alice's public key for decryption.

Bob, bob uses Alice's public key to decrypt the file. If the decryption succeeds, it proves that Alice's private key is correct and thus completes Alice's identity authentication. The authentication process is as follows:
Alice uses her private key to encrypt the file and sign the file.
Alice transfers the signed file to Bob.
Bob decrypts the file with Alice's public key to verify the signature.
Alice uses her own private key for encryption, and Bob uses Alice's public key f
Code is known and verified, and the Code has not been changed since the self-signature.
In the first case, trust an application without any damage and trust the source of the application. In the second case, use a digital signature to verify the authenticity. Digital signatures are industrial standards used to identify and provide detailed information about code senders. The technology is based on standard
1.1 concepts and functions of digital certificates
A digital certificate, also known as a digital identity, is a series of data that marks the identity information of network users. It provides an identity authentication method on the Internet, which is used to mark and prove the identity of both parties in the network
Digital Certificates are a series of data that mark the identity information of all parties in Internet communications. They provide a way to verify your identity on the Internet, its function is similar to the driver's driving license or ID card in daily life. It is issued by an authority-Ca, also known as the certificate authorit y center. People can use it online to identify each other. A
