.SH SYNOPSIS

.nf

|
.SH DESCRIPTION
|
|
Pass a pointer to a null\-terminated string holding the filename of the
|
|
known_host file to use. The known_hosts file should use the OpenSSH file
|
|
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
|
|
matching public key. Use \fICURLOPT_SSH_KEYFUNCTION(3)\fP to alter the default
|
|
behavior on host and key matches and mismatches.
|
|
|
|
The application does not have to keep the string around after setting this
|
|
option.
