NAME

Crypt::OpenSSL::Verify − OpenSSL Verify certificate verification in XS.

use Crypt::OpenSSL::Verify;
use Crypt::OpenSSL::X509;
my $ca = Crypt::OpenSSL::Verify−>new(
't/cacert.pem', # or undef
{
CApath => '/etc/ssl/certs', # Optional
noCAfile => 1, # Optional
noCApath => 0 # Optional
}
);
# Backward compatible with Crypt::OpenSSL:VerifyX509
my $ca = Crypt::OpenSSL::Verify−>new('t/cacert.pem');
# Using the defaults of your OS:
my $ca = Crypt::OpenSSL::Verify−>new();
# and later on..
my $cert = Crypt::OpenSSL::X509−>new(...);
$ca−>verify($cert);

The object created is similar to running the following command with the "openssl verify" command line tool: "openssl verify [ −CApath /path/to/certs ] [ −noCApath ] [ −noCAfile ] [ −CAfile /path/to/file ] cert.pem"

DESCRIPTION

Given a CA certificate and another untrusted certificate, will show whether the CA signs the certificate. This is a useful thing to have if you’re signing with X509 certificates, but outside of SSL.

A specific example is where you’re working with XML signatures, and need to verify that the signing certificate is valid.

METHODS

new()

Constructor. Returns an OpenSSL Verify instance, set up with the given CA.

my $ca = Crypt::OpenSSL::Verify−>new(
't/cacert.pem', # or undef
{
# Path to a directory containg hashed CA Certificates
CApath => $ca_path,
# Default CAfile should not be loaded if TRUE, defaults to FALSE
noCAfile => 0,
# Default CApath should not be loaded if TRUE, defaults to FALSE
noCApath => 0,
# Do not override any OpenSSL verify errors if FALSE, defaults to TRUE
strict_certs => 1,
}
);
# Backward compatible with Crypt::OpenSSL:VerifyX509
my $ca = Crypt::OpenSSL::Verify−>new('t/cacert.pem', {strict_certs => 0 });
# Using the defaults of your OS:
my $ca = Crypt::OpenSSL::Verify−>new();

verify($cert)

Verify the certificate is signed by the CA. Returns true if so, and croaks with the verification error if not.

Arguments:

* $cert − a Crypt::OpenSSL::X509 object for the certificate to verify.

ctx_error_code($ctx)

Calls the C code to obtain the OpenSSL error code of the verify and returns an integer value

Arguments:

* $ctx − a long unsigned integer containing the pointer to the
X509_STORE_CTX that was passed to the callback function
during the certificate verification

register_verify_cb(\&verify_callback);

Registers a Perl Sub as the callback function for OpenSSL to call during the registration process

Arguments:

* \&verify_callback − a reference to the verify_callback sub

verify_callback($ok, $ctx)

Called directly by OpenSSL and in the case of an acceptable error will change the response to 1 to signify no error

Arguments:

$ok − Error (0) or Success (1) from the OpenSSL certificate verification
results
$ctx − value of the pointer to the Certificate Store CTX used to access the
error codes that OpenSSL returned
