.SH DIAGNOSTICS
.\"  Bug added by Dan McDonald & Ran Atkinson (NRL)
.SH BUGS
.BR key(1)
can lull a user into revealing his/her password when remotely logged in.  This
is especially a problem with xterms and could be fixed by having the program 
check the DISPLAY environment variable before doing any key operations.
.br
Also, the key program can support either MD4 or MD5 depending on a compile-time
option.  That should really be a command line option with the key program 
supporting both algorithms.
