in reply to Best way to ask for password (cross-platform or Win32)

Check out CLI must not echo password or here is a Term::ReadKey example.(you may need to adjust $ord for backspace if in an xterm, but it works in console, etc)
#!/usr/bin/perl use strict; use Term::ReadKey; my $pwd = mask_pwd(); print "\n$pwd\n"; sub mask_pwd{ ReadMode(3); my $password = ''; print "Enter Password\n"; while(1){ my $ord = getord(); if ($ord == 10){last} # "Enter" if ($ord == 127) { # ie "Backspace" chop($password); print chr(8),' ',chr(8); next; } if($ord == 27){clearstream();$ord="\0"} if($ord != "\0"){ $password .= chr($ord); print '*'; } } ReadMode(0); return $password; } sub getord{ my $char; if (defined ($char = ReadKey(0))){} return ord($char); } sub clearstream{ while(1){ my $char; if (defined ($char = ReadKey(-1)) ){}else{return} } return ; }
