15 Pass a char * pointing to a filename for your public key. If not used,
16 libcurl defaults to $HOME/.ssh/id_dsa.pub if the HOME environment vari‐
17 able is set, and just "id_dsa.pub" in the current directory if HOME is
18 not set.
19
20 If NULL (or an empty string) is passed, libcurl will pass no public key
21 to libssh2, which then tries to compute it from the private key. This
22 is known to work with libssh2 1.4.0+ linked against OpenSSL.

24 The application does not have to keep the string around after setting
25 this option.
