If this +option isn't used or this bit is set to 0, the SSL layer libcurl uses may use a +work-around for this flaw although it might cause interoperability problems +with some (older) SSL implementations. WARNING: avoiding this work-around +lessens the security, and by setting this option to 1 you ask for exactly that. +This option is only supported for DarwinSSL, NSS and OpenSSL. + +Added in 7.44.0: + +\fICURLSSLOPT_NO_REVOKE\fP tells libcurl to disable certificate revocation +checks for those SSL backends where such behavior is present.
