SSL Parameters for Routes

The following table lists parameters that you can specify in the routes.conf configuration file, or on the command line when creating a route. The parameters for configuring SSL between routed servers are similar to the parameters used to configure SSL between server and clients; see SSL Protocol.

Parameter Description
ssl_identity The server’s digital certificate in PEM, DER, or PKCS#12 format. You can copy the digital certificate into the specification for this parameter, or you can specify the path to a file that contains the certificate in one of the supported formats.

For more information, see File Names for Certificates and Keys.

ssl_issuer Certificate chain member for the server. Supply the entire chain, including the CA root certificate. The server reads the certificates in the chain in the order they are presented in this parameter.

The certificates must be in PEM, DER, PKCS#7 or PKCS#12 format.

Example

ssl_issuer = certs\CA_root.pem
ssl_issuer = certs\CA_child1.pem
ssl_issuer = certs\CA_child2.pem

For more information, see File Names for Certificates and Keys.

ssl_private_key The local server’s private key. If the digital certificate in ssl_identity already includes this information, then you may omit this parameter.

This parameter accepts private keys in PEM, DER and PKCS#12 formats.

You can specify the actual key in this parameter, or you can specify a path to a file that contains the key.

For more information, see File Names for Certificates and Keys.

ssl_password Private key or password for private keys.

You can set passwords using the tibemsadmin tool. When passwords are set with this tool, the password is obfuscated in the configuration file. For more information, see Using the EMS Administration Tool.

ssl_trusted List of certificates that identify trusted certificate authorities.

The certificates must be in PEM, DER or PKCS#7 format. You can either provide the actual certificates, or you can specify a path to a file containing the certificate chain.

For more information, see File Names for Certificates and Keys.

ssl_verify_host Specifies whether the server must verify the other server’s certificate. The values for this parameter are enabled and disabled.

When omitted, the default is enabled, signifying the server must verify the other server’s certificate.

When this parameter is disabled, the server establishes secure communication with the other server, but does not verify the server’s identity.

ssl_verify_hostname Specifies whether the server must verify the name in the CN field of the other server’s certificate. The values for this parameter are enabled and disabled.

When omitted, the default is enabled, signifying the server must verify the name of the connected host or the name specified in the ssl_expected_hostname parameter against the value in the server’s certificate. If the names do not match, the connection is rejected.

When this parameter is disabled, the server establishes secure communication with the other server, but does not verify the server’s name.

ssl_expected_hostname Specifies the name expected in the CN field of the other server’s certificate. If this parameter is not set, the default is the hostname of the other server.

This parameter is relevant only when the ssl_verify_hostname parameter is enabled.

ssl_ciphers Specifies a list of cipher suites, separated by colons (:).

This parameter accepts both the OpenSSL name for cipher suites, or the longer descriptive names.

For information about available cipher suites and their names, see Specify Cipher Suites.
