I need the ability to safely prompt for a passphrase, of arbitrary
length, without echoing output.  This is like the getpass(3C) does,
but that truncates the input string and so calling that isn't good
enough to address the real requirement.

Not all applications of Java can assume that a GUI is available,
so AWT's setEchoChar stuff is not usable for this problem. 

EVALUATION Will provide a simple password-prompting facility much like that available in C as via the getpass(3C) function, in Mustang.


EVALUATION In addition to supporting getpass-like functionality, we should also look in to supporting simple line-oriented editing operations. These are necessarily somewhat platform-specific (e.g., Linux readline() vs. the DOS command prompt), but the addition of this feature would make it much easier to write simple non-GUI, command-driven programs. This RFE does not propose to define a general curses-like facility, which would be much more complex and, in a world where bitmapped displays are ubiquitous, arguably unnecessary. Under consideration for Tiger. -- ###@###.### 2002/2/20
