Name
easy:SetOpt_Proxy_CRLFile -- specify a proxy Certificate Revocation List file
Synopsis
easy:SetOpt_Proxy_CRLFile(file)
Function
This option is for connecting to an HTTPS proxy, not an HTTPS server.

Pass a string naming a file with the concatenation of CRL (in PEM format) to use in the certificate validation that occurs during the SSL exchange.

When curl is built to use NSS or GnuTLS, there is no way to influence the use of CRL passed to help in the verification process. When libcurl is built with OpenSSL support, X509_V_FLAG_CRL_CHECK and X509_V_FLAG_CRL_CHECK_ALL are both set, requiring CRL check against all the elements of the certificate chain if a CRL file is passed.

This option makes sense only when used in combination with the #CURLOPT_PROXY_SSL_VERIFYPEER option.

A specific error code (#CURLE_SSL_CRL_BADFILE) is defined with the option. It is returned when the SSL exchange fails because the CRL file cannot be loaded. A failure in certificate verification due to a revocation information found in the CRL does not trigger this specific error.
