CA, also known as the digital certificate Certification Center, is a trusted third party in e-commerce transactions. It is dedicated to solving the legality of public keys in the public key system. The CA center issues a digital certificate to each user who uses the public key. The role of the digital certificate is to prove that the user name listed in the

Introduction: In cryptography, the certificate is a very important concept, I do not want to expand here, the general certificate is based on the X.509 specification, interested students can see the corresponding introduction: http://en.wikipedia.org/wiki/X509 Practice: In fact, certificates are everywhere. In our browsers, we usually see some certificates, some of which are automatically added, and some c

In the previous article, we talked about common authentication methods: User Name/password authentication and Windows authentication. In the next article, we will introduce another important credential type: X.509 Certificate and the authentication method for X.509 Certificate. However, in order to allow readers to fully understand X.509 certificates, we need to first understand some background knowledge ab

All along, the issue of digital certificates, as well as trust and other things smattering. Finally have a leisurely weekend to summarize and delve into the relevant knowledge.Ca:A CA (Certificate authority) is the issuing authority for certificates, a third-party organization responsible for managing and issuing certificates, and a widely trusted institution. Generally in our computer, browser, or mobile phone will be built into a number of such a tr

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 private keys. Our users use public keys to encrypt data, and the corresponding private ke

SSL security technology can be used in most Web sites, which are primarily used to handle important security data. SSL establishes a secure encrypted connection between the server and the client, most commonly the connection between the Web server and the browser or the email client on the client computer. SSL is recognized as a security protocol because it specifies cryptographic algorithms and necessary variables for encrypted connections, and the purpose of secure connections using SSL is to

for the time being.Second, the working principle of HTTPSHTTPS requires a handshake between the client (browser) and the server (Web site) before transmitting the data, which establishes the password information for both parties to encrypt the transmitted data during the handshake. TLS/SSL protocol is not only a set of encrypted transmission protocols, but also an artist-designed artwork, TLS/SSL using asymmetric encryption, symmetric encryption and hash algorithm. A brief description of the ha

The main file types and protocols for certificates are: PEM, DER, PFX, JKS, KDB, CER, Key, CSR, CRT, CRL, OCSP, SCEP, etc. Pem–openssl uses the PEM (privacy enhanced Mail) format to hold various information, which is the default way of storing information in OpenSSL. The PEM file in Openssl generally contains the following information: Content type: Indicates what information is stored in this file, which is in the form of "——-BEGIN xxxx--" and corresponds to the end of "--end xxxx--". Header in

, security is no harm to guarantee. The HTTPS protocol is a good solution to this problem. According to Wikipedia (Http://zh.wikipedia.org/wiki/HTTPS), the main idea of HTTPS is to create a secure channel on an insecure network, and when using the appropriate encryption package and server certificate can be authenticated and trusted, Provide reasonable protection against eavesdropping and intermediary attacks. The trust inheritance for HTTPS is base

The certificate also contains both the public key and the key, which is used for encryption and the latter to decrypt. SQL Server can generate its own certificate, or it can be loaded from an external file or assembly. Because they can be backed up and loaded from a file, the certificate is easier to migrate than the asymmetric key, but the asymmetric key does no
