Most likely the file you're reading doesn't contain a private key in a
format that PEM_read_PriveKey likes. But the best way to tell is to use more
sensible error output code. For example, call ERR_print_errors_fp(stderr).
The 'perror' function will only work if the error was an error in a system
call. Most likely, the error was detected in the SSL code that tried to
process the data in the file.
