Here is my small patch to handle private key in memory:
http://ftp.intron.ac/tmp/openssl.c.diff
This feature is useful to work with a private key stored in a
USB key. I wish that this patch was useful to this project.
With this patch, if the argument "privatekey" of
libssh2_userauth_publickey_fromfile_ex() points to a string
starting with "mem://", the contents in the string after "mem://"
will be interpreted as a private key. Otherwise, the full contents
of "privatekey" is interpreted as a filename of private key.
Example:
char usbkeybuf[4096], pvk[4096];
/* Read a private key from USB key to usbkeybuf[] */
...
strcpy(pvk, "mem://");
strcat(pvk, usbkeybuf);
/*
pvk now contains
"mem://-----BEGIN RSA PRIVATE KEY-----\n"
...
"-----END RSA PRIVATE KEY-----"
*/
nret = libssh2_userauth_publickey_fromfile(session,
username, NULL, pvk, NULL);
