This tutorial shows how to implement real-world PKIs with the OpenSSL toolkit. openssl documentation: Iniziare con openssl. endobj The OpenSSL API is vast and complicated, so we won't attempt to provide anything like complete coverage here. For most uses, users should use the high level interface that is provided for performing cryptographic operations. It provides an encryption transport layer on top of the normal communications layer, allowing it to be intertwined with many network applications and services. Example Client code for TLS1.2 communication Learning how to use the API for OpenSSL -- the best-known open library for secure communication -- can be intimidating, because the documentation is incomplete. The openssl ca command takes its configuration from the [ca] section of the configuration file. The general syntax for calling openssl is as follows: Alternatively, you can call openssl without arguments to enter the interactive mode prompt.
