The Services–>Global Settings
page allows you to change the SSL cryptographic library
The page is organised into the section below.
The Host Cache Timer stores the IP Address of a real server when the
domain name has been used instead of an IP Address. The cache is
flushed upon a real server failure. Setting this value to zero will
never flush. There is no max value for this setting.
This global setting will change the SSL library used for client
side services. Open SSL is the default setting. There is an option to
change this to WolfSSL. More information can be found here about Wolf SSL.
