Hello all,
I have an abend when my perl script is finished. Everything it had to do was
done but It seems it doesn't know where to return correctly anymore. I
want to use this code to read an encrypted password in a file that would be
in my home profile. I wan't to avoir the use of text password in my code.
The password would be used to FTP files afterward.
Here is my sample code:
-----------------------------------
#!E:perl\bin\perl
use Win32::CryptData qw(:flags);
my $test_pass =
pack("H*","01000000d08c9ddf0115d1118c7a00c04fc297eb01000000714b346c6eb23f49b5da499fbaa672381400000002000000000003660000a800000010000000e64dae4c0cc12c4a7027c0787022c5fc0000000004800000a000000010000000580a364225d01271e119bc7b7430f45508000000cd6f4da09c7efa7d140000009a7c306010a5b5c64f0ade887848d6f3954d6674");
#Decrypted test password is "foobar"
print STDERR "Crypted password is :\n" . unpack("H*",$test_pass) .
"\n\n";
my $DataDescr = undef ;
my $OptionalEntropy = '11729';
my $Reserved = undef ;
my %PromptStruct = "";
my $Flags = CRYPTPROTECT_LOCAL_MACHINE | CRYPTPROTECT_UI_FORBIDDEN |
CRYPTPROTECT_AUDIT;
my $DataOut="";
my $ret = Win32::CryptData::CryptUnprotectData(\${test_pass},
\$DataDescr, \$OptionalEntropy, \$Reserved, \%PromptStruct, $Flags,
\$DataOut);
print "Password is : $DataOut and return code is: $ret\n";
if($ret!=1){die "Probleme with password\n"}
exit;
---------------------------------------------------------------------------------------------------------------------
After the perl script is finished I get the following error from windows:
Perl has encountered a problem and have to close. And bla.. bla... send
message to MS ...
details are:
------------------------------------------------------------------------------------------
AppName: perl.exe AppVer: 5.8.8.819 ModName: ntdll.dll
ModVer: 5.1.2600.2180 Offset: 00010c27
------------------------------------------------------------------------------------------
Any hints woud be welcome.
Regards,
BT
PS: You can't use the same crypted password on another machine but if you
want to test,
here is the "crypt.pl" routine I used to generate the encrypted
password.
It will return, in the standard output, the crypted password in text.
---------------- Crypt.pl
---------------------------------------------------------------------------
#!E:perl\bin\perl
# Modules
use strict;
use Win32::CryptData qw(:flags);
### Le code
my $DataIn = shift @ARGV || die "Text to encrypt ?";
my $DataDescr = undef;
my $OptionalEntropy = '11729';
my $Reserved = undef;
my %PromptStruct="";
my $Flags = CRYPTPROTECT_LOCAL_MACHINE | CRYPTPROTECT_UI_FORBIDDEN |
CRYPTPROTECT_AUDIT;
my $DataOut="";
my $ret = Win32::CryptData::CryptProtectData(\$DataIn, \$DataDescr,
\$OptionalEntropy, \$Reserved, \%PromptStruct, $Flags, \$DataOut);
if($ret)
{
print unpack("H*", $DataOut) . "\n";
}
else
{
print "Error: $^E\n";
}
