Where can I get perl cryptographic problems starting from simple programs?

How do I write a script in perl that signs a string with a certificate
(e.g. a SSL server certificate) to get a pkcs7 signature. I want a pkcs7
signature, because it contains the signing certificate and the ca.

Thanks
Peter

Dear Friends,

While trying to install Crypt::DES module on windows, I am
getting the following problem, so please help me to overcome this.

Hi,

Having just finished reading "Cryptography in the Database" by Kevin Kenan
of Symantic, I'm wondering if anyone has tackled the problem of writing a
local keystore in Perl, eg. the software equivalent of an HSM where
encryption keys can be semi-securely stored? The module I could find on the
CPAN that was remotely similar was Data::Encrypted. Alternatively, a program
written in another language that can be easily interfaced from Perl would
suffice..

Hi,

I am trying to get a Perl script together to parse my CRL's and am
getting the following error:

$VAR1 = bless( {'_error' => 'decode error at
/usr/local/share/perl/5.8.8/Convert/ASN1/_decode.pm line 57.' },
'Crypt::X509::CRL' );

Here is the script:

#!/usr/bin/perl -w
use Convert::ASN1;
use Crypt::X509::CRL;
use Data::Dumper;

$crl = "/home/fontenwp/workspace/crl_validation/ent.crl";

$decoded = Crypt::X509::CRL->new(crl => $crl);

print Dumper $decoded
