ABSTRACTCrypt::OpenSSL::PKCS10 - Perl extension to OpenSSL's PKCS10 API.
DESCRIPTIONCrypt::OpenSSL::PKCS10 provides the ability to create PKCS10
certificate requests using RSA key pairs.
Class Methods
new Create a new Crypt::OpenSSL::PKCS10 object by generating a new RSA
key pair. There is one optional argument, the key size, which has
the default value of 1024 if omitted.
new_from_rsa( $rsa_object )
Create a new Crypt::OpenSSL::PKCS10 object by using key information
from a Crypt::OpenSSL::RSA object. Here is an example:
my $rsa = Crypt::OpenSSL::RSA->generate_key(512);
my $req = Crypt::OpenSSL::PKCS10->new_from_rsa($rsa);
Instance Methods
set_subject($subject)
Sets the subject DN of the request. Note: $subject is expected to be
in the format /type0=value0/type1=value1/type2=... where characters
may be escaped by \
add_ext($nid, $extension)
Adds a new extension to the request. The first argument $nid is one
of the exported constants (see below). The second one $extension is
a string (for more info read openssl(3)).
$req->add_ext(Crypt::OpenSSL::PKCS10::NID_key_usage,"critical,digitalSignature,keyEncipherment");
$req->add_ext(Crypt::OpenSSL::PKCS10::NID_ext_key_usage,"serverAuth, nsSGC, msSGC, 1.3.4");
$req->add_ext(Crypt::OpenSSL::PKCS10::NID_subject_alt_name,"email:steve@openssl.org");
add_custom_ext($oid, $desc)
Adds a new custom extension to the request.
$req->add_custom_ext('1.2.3.3',"My new extension");
add_ext_final()
This must be called after all extensions has been added. It actually
copies the extension stack to request structure.
$req->add_ext(Crypt::OpenSSL::PKCS10::NID_subject_alt_name,"email:my@email.org");
$req->add_ext_final();
sign()
This adds the signature to the PKCS10 request.
$req->sign();
get_pem_req()
Returns the PEM encoding of the PKCS10 request.
$req->get_pem_req();
write_pem_req($filename)
Writes the PEM encoding of the PKCS10 request to a given file.
$req->write_pem_req('request.pem');
get_pem_pk()
Returns the PEM encoding of the private key.
$req->get_pem_pk();
write_pem_pk($filename)
Writes the PEM encoding of the private key to a given file.
$req->write_pem_pk('request.pem');
EXPORT
None by default.
On request:
NID_key_usage NID_subject_alt_name NID_netscape_cert_type NID_netscape_comment
NID_ext_key_usage
BUGS
If you destroy $req object that is linked to a Crypt::OpenSSL::RSA
object, the RSA private key is also freed, thus you can't use latter
object anymore. Avoid this:
my $rsa = Crypt::OpenSSL::RSA->generate_key(512);
my $req = Crypt::OpenSSL::PKCS10->new_from_rsa($rsa);
undef $req;
print $rsa->get_private_key_string();
