WebAuth WebKDC KEYRING timestamp Allbery
=head1 NAME
WebAuth::Token::Cred - WebAuth cred tokens
=head1 SYNOPSIS
my $token = WebAuth::Token::Cred->new;
$token->subject ('user');
$token->type ('krb5');
$token->service ('service/foo@EXAMPLE.COM');
$token->data ($ticket);
$token->creation (time);
$token->expiration (time + 3600);
print $token->encode ($keyring), "\n";
=head1 DESCRIPTION
A WebAuth cred token, which holds a credential for some other service,
usually a Kerberos service ticket. It is sent back by the WebKDC to a
WebAuth Application Server when requested using a proxy token, and the WAS
also uses it to store the credentials in cookies.
=head1 CLASS METHODS
=over 4
=item new ()
Create a new, empty WebAuth::Token::Cred. At least some attributes will
have to be set using the accessor methods described below before the token
can be used.
=back
=head1 INSTANCE METHODS
As with WebAuth module functions, failures are signaled by throwing
WebAuth::Exception rather than by return status.
=head1 General Methods
=over 4
=item encode (KEYRING)
Generate the encoded and encrypted form of this token using the provided
KEYRING. The encryption key used will be the one returned by the
best_key() method of WebAuth::Keyring on that KEYRING.
=back
=head1 Accessor Methods
=over 4
=item subject ([SUBJECT])
Get or set the subject, which holds the identity of the user for which
this token contains credentials.
=item type ([TYPE])
Get or set the type of credential stored in this token. Currently, this
is always C<krb5> (but still must be explicitly set if creating a new
token).
=item service ([SERVICE])
Get or set the service for which this token stores a credential. For
tokens of type C<krb5>, this is the fully-qualified principal name of
the service ticket stored in this token.
=item data ([CREDENTIAL])
Get or set the credential stored in this token. This is currently always
a Kerberos ticket in the form created by the export_cred() method of the
WebAuth::Krb5 module.
=item creation ([TIMESTAMP])
Get or set the creation timestamp for this token in seconds since epoch.
If not set, the encoded token will have a creation time set to the time of
encoding.
=item expiration ([TIMESTAMP])
Get or set the expiration timestamp for this token in seconds since epoch.
