Thanks.

To Howard,

I think getpassphrase(3) is Solaris specific interface and not part of
standard.  On FreeBSD, getpass(3) returns a buffer pointer that contains
at most 128 (_PASSWORD_LEN) characters, which should fulfill the need of
OpenBSD but shorter than Solaris[1] which have 256, not counting the
terminating nul character.

Note that FreeBSD do have a readpassphrase(3) extension which provide
more flexibility.  I am not sure, however, whether we should implement
the Solaris behavior for getpassphrase(3), as it's not a standard
defined interface?  Is there any other operating system that provide
getpassphrase(3) and have the same behavior?

If it's desirable we could have it implemented on FreeBSD this way:

=================
char *
getpassrase(const char *prompt)
{
        static char buf[256 + 1];

        return(readpassphrase(prompt, buf, sizeof(buf), RPP_ECHO_OFF));
}
=================

Please advise, thanks!
