Some potentially working code :

#!perl #use strict; use Win32::API::Prototype; ApiLink( 'eq_handy.dll', 'BOOL bgfnTextDecrypt( LPSTR lpString, LPSTR +, lpBuffer )' ) || die ($!); my $passphrase="encrypt-phrase"; my $lpString = pack( "L2", $passphrase,0); print "Hi there\n"; $nBufferLength = 256; $lpBuffer = NewString( $nBufferLength ); if (bgfnTextDecrypt($lpString,$lpBuffer, $nBufferLength)) { print "It worked!\n"; } my $pass = unpack( "L*", $lpBuffer ); print "The pass is:",$pass,"\n";
Output is:
Hi there It worked! The pass is:189
The actual pass is bluemean.
I think my unpack is wrong.. any suggestions?
