Self-built CA Based on OpenSSL and SSL certificate issuance For details about SSL/TLS, see the SSL/TLS principles.For more information about Certificate Authority (CA) and digital certificate, see OpenSSL and SSL digital certificate concepts. Openssl is a suite of open-source programs. It consists of three parts: one islibcryto, This is a general function of the encryption library, which implements a large number of encryption libraries; secondlibsslThis implements the ssl mechanism. It is used

electronic transactions or electronic transfers need to ensure that users are securely connected to their websites. To achieve this, these organizations need to issue their own public key certificates by internationally recognized CAS (such as VeriSign. These certificates are used to establish SSL connections or decrypt electronic signatures. The process of applying for a certificate must be verified by the CA. At the same time, the CA must pay a hig

key exchange and digital signature, and of course, if you can tolerate its slow speed, it can also be used for data encryption. The DSA algorithm is generally used only for digital signatures.3. Information Digest algorithmOpenSSL implements 5 information digest algorithms, namely MD2, MD5, MDC2, SHA (SHA1), and RIPEMD. The SHA algorithm actually includes the SHA and SHA1 two kinds of information digest algorithms, in addition, OpenSSL implements two kinds of information digest algorithms, DSS

, and the other can bind the public key and its related information to the declared owner in a trusted way.This is the certificate mechanism. The certificate is an authoritative document in e-commerce. The certificate issuer must be trustworthy, it is issued by authoritative, trustable, and impartial third-party organizations. Certificates are a security mechanism that ensures the implementation and completion of PKI identity authentication, integrity

1. First to generate the server-side private key (key file):Command:OpenSSL genrsa-des3-out Server.key 1024The runtime prompts for a password, which is used to encrypt the key file (the parameter des3 is the encryption algorithm, and of course you can choose other algorithms that you think are safe). You need to enter a password whenever you need to read this file (via the command or API provided by OpenSSL)2. Generate CSR and key on the serverCommand:OpenSSL Req-new-key server.key-out server.cs

the browser can be checked through the certificate storage area. The certificate storage area provides information about the CA certificate, and the CA certificate is stored in the browser storage. At the same time, the CA website also provides browser SSL compatibility information. The following picture shows the details of the certificate for the sample Website http://abcgen.uk. The certificate ensures that the reliability of the owner has been verified. The digital certificate is issued to A

The previous article introduced some basic questions about SSL two-way authentication and used nginx + PHP to build https-based WebService. The previous method only implemented the mode. Yesterday, my colleagues continued to implement the N: 1 mode. Here I will record it again. Because the ssl_client_certificate parameter of nginx can only specify one client public key, if a client is added for communication, a server is required. The N: 1 mode is implemented through the CA cascade certificate m

the previous approach was just to implement the 1:1 pattern, and yesterday colleagues continued to implement the N:1 model, and here I'm going to sort it out. Since Nginx's ssl_client_certificate parameter can only specify a client public key, it is necessary to re-match a server if a client is added to communicate. The N:1 pattern is implemented through the CA's cascading certificate pattern, first generating a set of CA root-level certificates and then generating level two certificates as cl
