.SH DESCRIPTION
|
2020-06-25 17:38:25 +08:00
|
|
|
Pass a pointer to a null-terminated string holding the file name of the
|
2014-06-19 23:59:00 +08:00
|
|
|
known_host file to use. The known_hosts file should use the OpenSSH file
|
2023-08-22 23:40:39 +08:00
|
|
|
format as supported by libssh2. If this file is specified, libcurl only
|
|
|
|
|
accepts connections with hosts that are known and present in that file, with a
|
2014-06-19 23:59:00 +08:00
|
|
|
matching public key. Use \fICURLOPT_SSH_KEYFUNCTION(3)\fP to alter the default
|
2022-09-21 05:30:19 +08:00
|
|
|
behavior on host and key matches and mismatches.
|
2016-12-21 21:48:35 +08:00
|
|
|
|
|
|
|
|
The application does not have to keep the string around after setting this
|
|
|
|
|
option.
