Support for TLS 1. Specifies the path to a configuration file and the directory for included files. openssl ca -config . Another solution consists of using the prompt = no directive in your config file. Many commands use an external configuration file for some or all of their arguments and have a -config option to specify that file. tst -token_in -CAfile certificate. pem)A CSR (Certificate Signing Request)A public If the OpenSSL configuration file is defined well, then we could use -config myopenssl.
