If you need to reprint it, please indicate the source I have studied SSL/TLS some time ago and read the English version of Eric rescorla's SSL and TLS-designing and building secure systems (for the severity of the Chinese version, I wrote a previous articleBlog has been severely criticized ). The author of this book follows the idea of Steven s in his role of TCP/IP authentication strated: us

OrderThe previous article introduced several concepts related to CA certificates, which are important to understand the digital certificate and how it works. This article is mainly to analyze the CA certificate, to tell the basic composition of the certificate, which is necessary to generate a correct, accessible certificate.ConstituteNonsense not much to say, di

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

said earlier that message digest is used to verify data integrity, and symmetric and asymmetric encryption is used to guarantee data confidentiality. Data signatures are used for the anti-repudiation of data, so the ultimate weapon that sets these security measures--digital certificates--appears. Digital certificate has the necessary information of encryption/decryption, including signature algorithm, can be used for network data encryption/decryption

So read some online information, here to do a summary.1.

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

How to apply online has a detailed introduction, do not do more in this introduction. The difference between an Apple Personal/corporate developer account and the app release: a release

What is CA: CA (Certificate authority) is the abbreviation of digital Certificate Certification Center, refers to the issuing, management, abolition of digital certificate institutions. The role of a CA is to check the legitimacy of the identity of the certificate holder and issue a

During the real machine test, I followed the online process and passed the test. At that time, I did not pay attention to the meaning of various certificates. Currently, message pushing requires various certificates and app id information. In order to better understand this process, I sorted out relevant information about certificates and so on. It is convenient for you and friends in need. Content reference: http://blog.csdn.net/hitwhylz/article/details/22989507 Http://my.oschina.net/u/1245365

lower than that of symmetric encryption and decryption algorithms. Therefore, SSL uses asymmetric cryptographic algorithms to negotiate keys during the handshake process, and uses symmetric encryption and decryption methods to Encrypt transmission of HTTP content. The following is a metaphor for the image of this process (from http://blog.chinaunix.net/u2/82806/showart_1341720.html ): Assume that a communicates with B, A is an SSL client, B is an SSL server, and encrypted messages are placed i

Digital Certificate and Its Application in Security Testing0x00 background To perform security tests on the Web layer, it is inevitable that a man-in-the-middle proxy will be used to capture packets for analysis. Common tools include BurpSuit, Fiddker, and Charles. The usage of these tools has been described on the Internet. I will not go into details here. However, when testing websites with high security, you may encounter SSL communication problems

Handshake and communication over the SSL protocol To better understand and understand the SSL protocol, we will introduce the handshake protocol of the SSL protocol. SSL uses both public key encryption and symmetric encryption. Although symmetric encryption is faster than public key encryption, public key encryption provides better identity authentication. The SSL handshake protocol is very effective for customers and servers to complete identity authentication. The main process is as follows:①
