Wise Builds cURL Options

Allows configuration of cURL connection options.

Description: Allows configuration and testing of cURL connection options for individual services such as Paypal or Moneris who have changing connection requirements that the WordPress defaults may not satisfy on your server.

Please refer to the PHP documentation for options and valid values:

Note the versions of PHP when various constants were defined. Some constant option values such as CURL_SSLVERSION_TLSv1_2 for CURLOPT_SSLVERSION can still be set using their integer values prior to their definition in PHP. There will be some trial and error involved to determine what works on your server depending on the version of PHP and cURL and which cryptography library was used to build cURL. Thus the testing function, which should come in handy for this (at least for http(s) POST requests).

Note the cipher suite string formats for CURLOPT_SSL_CIPHER_LIST option values are dependent on the cryptography library that was used to build cURL:

(Unfortunatly the NSS cipher names seem to only be available there where the file is served as plain text, you can save it locally to view the page in your browser)

Note that for cURL built with NSS, the mod_nss-style cipher definitions do not appear to work; the individual cipher names must be used. Cipher strings may work with cURL built with OpenSSL. Again, there will be some trial and error involved to determine what works on your server.

For advanced users, site administrators and developers.
