Hello Monks.

Just tired using Win32::CryptData. Seeking your help.

Little background. I am not much qualified in Perl.

Working on a windows machine with perl(cygwin). I have created several .rdp files for automatic logon on few remote machines. Need to enter password in this field - "password 51:b:" - in encrypted state.

Picked up the module and used below code stated in module's documentation. 

use strict;
use Win32::CryptData qw(:flags);

my $DataIn          = '<mypassword>';
my $DataDescr       = 'This is the description';
my $OptionalEntropy = 'mysecret';
my $Reserved        = undef;
my %PromptStruct    = (
    PromptFlags => CRYPTPROTECT_PROMPT_ON_PROTECT | CRYPTPROTECT_PROMP
+T_ON_UNPROTECT |
        CRYPTPROTECT_PROMPT_STRONG,
    hwndApp => undef,
    Prompt  => 'This is the caption'
);
my $Flags = CRYPTPROTECT_AUDIT;
my $DataOut;

my $ret =
    Win32::CryptData::CryptProtectData( \$DataIn, \$DataDescr, \$Optio
+nalEntropy, \$Reserved,
    \%PromptStruct, $Flags, \$DataOut );

if ($ret) {
    print "Encrypted data (hex): " . unpack( "H*", $DataOut ) . "\n";
}
else {
    print "Error: $^E\n";
}

I have tried both medium and high security level. It creates a password but that is not working through rdp files.

Someone gave me a self-made .exe in C-Sharp code, which gives an encrypted password and makes that rdp file work properly.

Please help me in understanding whats the problem in perl code, that I can't get correct encryption.

Also, the password given by perl script is very different and much longer than the one given by C-Sharp exe.
