A value of 1 means curl verifies; 0 (zero) means it doesn't. + +When negotiating a TLS or SSL connection, the server sends a certificate +indicating its identity. Curl verifies whether the certificate is authentic, +i.e. that you can trust that the server is who the certificate says it is. +This trust is based on a chain of digital signatures, rooted in certification +authority (CA) certificates you supply. curl uses a default bundle of CA +certificates (the path for that is determined at build time) and you can +specify alternate certificates with the \fICURLOPT_CAINFO(3)\fP option or the +\fICURLOPT_CAPATH(3)\fP option. + +When \fICURLOPT_SSL_VERIFYPEER(3)\fP is enabled, and the verification fails to +prove that the certificate is authentic, the connection fails. When the +option is zero, the peer certificate verification succeeds regardless. + +Authenticating the certificate is not enough to be sure about the server. You +typically also want to ensure that the server is the server you mean to be +talking to. Use \fICURLOPT_SSL_VERIFYHOST(3)\fP for that. The check that the +host name in the certificate is valid for the host name you're connecting to +is done independently of the \fICURLOPT_SSL_VERIFYPEER(3)\fP option. +.SH DEFAULT +By default, curl assumes a value of 1. +.SH PROTOCOLS +All TLS based protocols: HTTPS, FTPS, IMAPS, POP3, SMTPS etc. +.SH EXAMPLE +TODO +.SH AVAILABILITY +If built TLS enabled. +.SH RETURN VALUE +Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. +.SH "SEE ALSO" +.BR CURLOPT_SSL_VERIFYHOST "(3), " |
