Openssl config software#
Generally, group access is enabled to allow an unprivileged user to backup the database, and in that case the backup software will not be able to read the certificate files and will likely error. If the data directory allows group read access then certificate files may need to be located outside of the data directory in order to conform to the security requirements outlined above. The user under which the PostgreSQL server runs should then be made a member of the group that has access to those certificate and key files. That setup is intended for installations where certificate and key files are managed by the operating system. Alternatively, the file can be owned by root and have group read access (that is, 0640 permissions). On Unix systems, the permissions on server.key must disallow any access to world or group achieve this by the command chmod 0600 server.key. By default, these files are expected to be named server.crt and server.key, respectively, in the server's data directory, but other names and locations can be specified using the configuration parameters ssl_cert_file and ssl_key_file. To start in SSL mode, files containing the server certificate and private key must exist.
Openssl config how to#
By default, this is at the client's option see Section 21.1 about how to set up the server to require use of SSL for some or all connections. The server will listen for both normal and SSL connections on the same TCP port, and will negotiate with any connecting client on whether to use SSL.
Set OPENSSL_CONF=C:\Program Files (x86)\Micro Focus\DemoCA\openssl.With SSL support compiled in, the PostgreSQL server can be started with SSL enabled by setting the parameter ssl to on in nf. One is included with the Micro Focus DemoCA, in the main directory of the DemoCA installation. If you receive a warning message like " WARNING: can't open config file: /usr/local/ssl/openssl.cnf" from the OpenSSL utility, set the environment variable OPENSSL_CONF to the location of a suitable MKS Software site and page down to the section on the In the options in the configuration file, all filenames must be given complete with absolute path. Of the attributes section is specified in the req section, so that you can have several attributes sections, and switch between Like the distinguished_name section, the actual name This enables you to switch between different distinguished_name configurations, by changing the entry in the req section.Īttributes, which has attributes such as challengePassword or unstructuredName. The actual name of this section is specified in the distinguished_name entry in the req section. Req section, which configures the openssl req command.ĭistinguished_name section, which specifies the Distinguished Name fields required when the openssl req command is creating a certificate request Policy section, which specifies how closely the Distinguished Name in a certificate presented to SSL software must agree with theĭistinguished Name in an installed certificate, for the two certificates to be considered to match. This is useful in development and testing, enabling you to try out different configurations. You can also override this choice from the command line, using the You can have several ca sections, each specifying a different configuration for a differentĬA, and switch between them by changing theĭefault_ca option. The configuration file is a text file and comprises several sections, such as:Ĭa section, which configures the CA. You can specify a different configuration file by using the OPENSSL_CONF environment variable or you can specifyĪlternative configurations within one configuration file. Openssl.cnf by default and belongs in the same directory as Defaults for the openssl ca policy command, which specifies which elements of the Distinguished Name are required.
