NAME
Crypt::OpenSSL::PKCS12 - Perl extension to OpenSSL's PKCS12 API.
SYNOPSIS
use Crypt::OpenSSL::PKCS12;
my $pass = "your password";
my $pkcs12 = Crypt::OpenSSL::PKCS12->new_from_file('cert.p12');
print $pkcs12->certificate($pass);
print $pkcs12->private_key($pass);
if ($pkcs12->mac_ok($pass)) {
...
# Creating a file
$pkcs12->create('test-cert.pem', 'test-key.pem', $pass, 'out.p12', 'friendly name');
# Creating a string
my $pksc12_data = $pkcs12->create_as_string('test-cert.pem', 'test-key.pem', $pass, 'friendly name');
# Reproducing OpenSSL's info
my $info = $pkcs12->info($pass);
# Accessing OpenSSL's info as a hash
my $info_hash = $pkcs12->info_as_hash($pass);
VERSION
This documentation describes version 1.94 of Crypt::OpenSSL::PKCS12
DESCRIPTION
PKCS12 is a file format for storing cryptography objects as a single file or string. PKCS12 is commonly
used to bundle a private key with its X.509 certificate or to bundle all the members of a chain of trust.
This distribution implements a subset of OpenSSL's PKCS12 API.
SUBROUTINES/METHODS
• new( )
• legacy_support ( )
Check whether the openssl version installed supports the legacy provider.
• new_from_string( $string )
• new_from_file( $filename )
Create a new Crypt::OpenSSL::PKCS12 instance.
• certificate( [$pass] )
Get the Base64 representation of the certificate.
• ca_certificate( [$pass] )
Get the Base64 representation of the CA certificate chain.
• private_key( [$pass] )
Get the Base64 representation of the private key.
• as_string( [$pass] )
Get the binary represenation as a string.
• mac_ok( [$pass] )
Verifiy the certificates Message Authentication Code
• changepass( $old, $new )
Change a certificate's password.
• create( $cert, $key, $pass, $output_file, $friendly_name )
Create a new PKCS12 certificate. $cert & $key may either be strings or filenames.
$friendly_name is optional.
• create_as_string( $cert, $key, $pass, $friendly_name )
Create a new PKCS12 certificate string. $cert & $key may either be strings or filenames.
$friendly_name is optional.
Returns a string holding the PKCS12 certicate.
• info( $pass )
Returns a string containing the output of information about the pkcs12 file in the same format as
produced by the openssl command:
openssl pkcs12 -in certs/test_le_1.1.p12 -info -nodes
• info_as_hash( $pass )
Places the information about the pkcs12 file, the certificates and keys in a hash.
The format of the hash is complex to represent the data in the PKCS12 file:
Essentially, the hash follows the format of the -info output.
1. pkcs7_data and pkcs7_encrypted_data are arrays as more than one of each can exist 2. mac provieds
the top level mac parameters for the file 3. safe_contents_bag is an array that contains an array of
bags 4. bags is an array of bags 5. a bag is a container for a key or certificate
Each bag has a type and the following are available:
1. key_bag 2. certificate_bag 3. shrouded_keybag 4. secret_bag 5. safe_contents_bag
