curl passes down the capath directly to the backends. OpenSSL will then delimiter-separate this path internally to support multiple directories (using its certificate hash scheme). However, the other backends (wolfSSL, mbedTLS, gnutls) only expect a single directory (and do not use the hash scheme, preferring to iterate the directory and load all files). This adjusts the `--capath` documentation to reflect that multiple paths is an OpenSSL-specific feature. Alternatively, curl could delimiter-separate these itself, but I'm not sure it's worth it.

# `--capath`
|
|
|
|
Use the specified certificate directory to verify the peer. If curl is built against
|
|
OpenSSL, multiple paths can be provided by separating them with the appropriate platform-specific
|
|
separator (e.g. `path1:path2:path3` on Unix-style platforms for `path1;path2;path3` on Windows).
|
|
|
|
The certificates must be in PEM format, and if curl is built against OpenSSL, the
|
|
directory must have been processed using the c_rehash utility supplied with
|
|
OpenSSL. Using --capath can allow OpenSSL-powered curl to make SSL-connections
|
|
much more efficiently than using --cacert if the --cacert file contains many
|
|
CA certificates.
|
|
|
|
If this option is set, the default capath value is ignored.
