Description of several format files:Csr--> the files generated on the F5. Contains the domain name, company name, department name, city, mailbox and other information.Crt/cer--> public key, certificate file, issued by an authoritative certificate authority.Key--> the private key, which is generated in pairs with the CSR.Cases:1_root_bundle.crt--> certificate chai

I. Theoretical knowledge What is ca? Ca is short for Certificate Authority. It is usually translated into an authentication authority or a certification center. It is mainly used to issue digital certificates to users. This digital certificate contains part of the user's identity information and the public key held by the user. At the same time, the private key of the CA is used to add a digital signature

This feature is not commonly used, the general development of less related to the certificate, but it is necessary to understand briefly.First of all, the method of making the test certificate, here the old week to talk about two methods, you can generate a. pfx file for testing.To produce a certificate, everyone knows there is a makecert tool. OK, let's start wi

I. Introduction of OpenSSL OpenSSL is currently the most popular SSL cipher library tool that provides a common, robust, and fully functional suite of tools to support the implementation of the SSL/TLS protocol.Official website: https://www.openssl.org/source/ component cipher algorithm library key and certificate encapsulation management function SSL Communication API Interface use establish RSA, DH, DSA key parameter establish the

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

What is a security certificate A security certificate is an identity card, or a private key, on an online transaction, and your security certificate is unique, unlike any other person's certificate. To prevent duplication, we are not saving the security certificate when we

Brief DescriptionBackgroundA good j2_application finally does not need to prompt annoying messages when the program reads system resources (such as network, SMS, Pim, and file. The purpose of this article is to explore this knowledge. ContentThe j2's certificate can solve the above problems. This article mainly summarizes some solutions and experiences on the network. Expected readers and SuggestionsDevelopers who need to have a visa for the j2_progra

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

Turn from: HTTPS Unidirectional authentication Instructions _ digital certificate, digital signature, SSL (TLS), SASLBecause TLS + SASL is used in the project to do the security authentication layer. So read some online information, here to do a summary.1.

This component encapsulates the certificate management, verification, and security authentication functions of the Web application system after logon, providing developers with a convenient and easy-to-use and highly scalable Security

CryptoAPI programming (1) Microsoft Encryption Service System The structure of the Microsoft cryptographic Service System CryptoAPI as shown in the following illustration, the Microsoft Encryption Service system consists of three-tier architecture and two interfaces, namely the application layer, the operating system layer (OS), the cryptographic service provider layer (cryptographic service PROVIDER,CSP), The CryptoAPI interface and the cryptographic service Provider Interface (the cryptograp

To successfully set up SSL security site key to have the following conditions. 1, need to obtain the server certificate from the trusted certificate mechanism ca.2, you must install the server certificate on the Web server.3. The SSL feature must be enabled on the Web server.4. The client (browser-side) must trust the same certification authority as the Web serve

Recently the company website to use HTTPS, from their own groping to find the domestic free certificate to purchase a formal fee certificate, finally the boss said: too expensive. No. A face to listen to the boss said let ' s encrypt certificate, no way, with Bai. Before there is some understanding, a foreign release of a pure free

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

You may be unfamiliar with the concept of "Digital Certificate". In fact, digital certificates are a series of data that marks the identity information of network users. They are used to identify the identities of communication parties in network communication, that is to say, we need to solve the problem of "who I am" on the Internet, just as in reality, each of us needs an ID card or driver's license to prove our identity, to indicate our identity o

1. After OpenSSL is installed, find OpenSSL. CnF in the/usr/lib/SSL directory (for Ubuntu system, use whereis to check the SSL directory) and copy it to the working directory. 2. Create a New democafolder under the Work directory, create the new files index.txt and serial in the folder, and then create a newcerts folder. Add the character 01 to serial. Mkdir democa CD democa Touch./{serial, index.txt} Add 01: WQ to VI serial Certificate generation pro

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
