The operating system needs to install OpenSSL, and this part of the operation should be performed as a system administrator, therefore, the following command line uses the "#" identifier to start the header.After OpenSSL is installed, the system will generate the openssl. cnf file under the/etc/ssl/Directory (different operating systems may

Use the OpenSSL to verify the certificate chain with the following command:Debian:/home/zhaoya/openssl#openssl verify-cafile Root_cert User_certThe Root_cert can contain a lot of certificates, you can use the Cat command to merge multilevel CA certificates into a file, and then the program will load after startup Root_

OpenSSL Toolkit is one of the implementation methods of SSL v2/V3 and TLS v1 protocols on Linux, and provides common encryption and decryption functions. OpenSSLIt consists of three parts: 1:Libcrypto: an encrypted library mainly used to implement encryption and decryption. 2:Libssl: implements the SSL server-side function session Library 3:OpenSSL command line tool:/usr/bin/

Create your own CA certificate $ OpenSSL req-New-X509-keyout ca. Key-out ca. CRT 4. Generate the private key (key file) and CSR file of the server.

Certificate file generation Many may have the same deep experience as myself. Using the OpenSSL library to write an encrypted communication process, the code can be easily written, but the entire work has taken several days. Except for compiling the program successfully (no certificate file can be used, it is compiled successfully and cannot run, it does not mea

Under the Windows platform, if you want to parse a X509 certificate file, the most straightforward way is to use Microsoft's CryptoAPI. But under the non-Windows platform, you can only use the powerful open source cross-platform library OpenSSL. After a X509 certificate is decoded by OpenSSL, a struct pointer of the X5
