=head1 NAME

Net::SSLeay::OO::X509::Name - methods to call on SSL certificate names

=head1 SYNOPSIS

 my $name = $cert->get_subject_name;

 # for 'common' attributes
 print "Summary of cert: ".$name->oneline."\n";
 print "Common name is ".$name->cn."\n";

 # others...
 use Net::SSLeay::OO::Constants qw(NID_pbe_WithSHA1And2_Key_TripleDES_CBC);
 my $val = $name->get_text_by_NID(NID_pbe_WithSHA1And2_Key_TripleDES_CBC);

=head1 DESCRIPTION

This object represents the X509_NAME structure in OpenSSL.  It has a
bunch of fields such as "common name", etc.

Two methods are imported from the OpenSSL library;

=over

=item B<oneline>

Returns a string, such as:

 /C=NZ/ST=Wellington/O=Catalyst IT/OU=Security/CN=Test Client

=item B<get_text_by_NID(NID_xxx)>

Return a given field from the name.  See F<openssl/objects.h> for the
complete list.

=back

Convenience methods have been added which return the following common
fields:

        cn           NID_commonName
	country      NID_countryName
	locality     NID_localityName
	state        NID_stateOrProvinceName
	org          NID_organizationName
	org_unit     NID_organizationalUnitName
	subject_key  NID_subject_key_identifier
	key_usage    NID_key_usage
	serial       NID_serialNumber
