CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSH_PUBLIC_KEYFILE,
Pass a char * pointing to a filename for your public key. If not used,
libcurl defaults to $HOME/.ssh/id_dsa.pub if the HOME environment
variable is set, and just "id_dsa.pub" in the current directory if HOME

is known to work with libssh2 1.4.0+ linked against OpenSSL.
The application does not have to keep the string around after setting
