Note that certificate chain validation is always ensured when the cert authentication method is used (see Section 21.12). If clientcert=verify-full is specified, the server will not only verify the certificate chain, but it will also check whether the username or its mapping matches the cn (Common Name) of the provided certificate.

(See Section 34.19 for a description of how to set up certificates on the client.)įor a hostssl entry with clientcert=verify-ca, the server will verify that the client's certificate is signed by one of the trusted certificate authorities. A certificate will then be requested from the client during SSL connection startup. To require the client to supply a trusted certificate, place certificates of the root certificate authorities ( CAs) you trust in a file in the data directory, set the parameter ssl_ca_file in nf to the new file name, and add the authentication option clientcert=verify-ca or clientcert=verify-full to the appropriate hostssl line(s) in pg_hba.conf. Instead, clients must have the root certificate of the server's certificate chain. It is not necessary to add the root certificate to server.crt. (This sets the certificate's basic constraint of CA to true.) This allows easier expiration of intermediate certificates. Doing this avoids the necessity of storing intermediate certificates on clients, assuming the root and intermediate certificates were created with v3_ca extensions. The certificates of “ intermediate” certificate authorities can also be appended to the file. The first certificate in server.crt must be the server's certificate because it must match the server's private key. Furthermore, passphrase-protected private keys cannot be used at all on Windows.
Using a passphrase by default disables the ability to change the server's SSL configuration without a server restart, but see ssl_passphrase_command_supports_reload. If the private key is protected with a passphrase, the server will prompt for the passphrase and will not start until it has been entered.

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. 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. With SSL support compiled in, the PostgreSQL server can be started with support for encrypted connections using TLS protocols enabled by setting the parameter ssl to on in nf.
