TLSDHParamFile [ Absolute path to the Diffie-Hellman param file]
Default
None
Context
server config, <Global>, <VirtualHost>
Module
mod_tls
Compatibility
1.2.7rc1 and later
The TLSDHParamFile directive is used to configure a file that mod_tls will use when engaging in a Diffie-Hellman key exchange. Such a key exchange can be computationally intensive, in terms for parameter generation; to help speed up the process, the parameters used may be generated in advance, and stored in a file. The dhparam utility that comes with OpenSSL may be used to generate an appropriate file for this directive. The file parameter must be an absolute path.
