The first form is used to communicate the session key for WebKDC communication across a pool of WebAuth Application Servers that the user may visit interchangeably while accessing the same \s-1URL.\s0 The second form is used to record the authenticated identity of the user for a session on a WebAuth Application Server. .SH "CLASS METHODS" .IX Header "CLASS METHODS" .IP "new ()" 4 .IX Item "new ()" Create a new, empty WebAuth::Token::App. At least some attributes will have to be set using the accessor methods described below before the token can be used. .SH "INSTANCE METHODS" .IX Header "INSTANCE METHODS" As with WebAuth module functions, failures are signaled by throwing WebAuth::Exception rather than by return status. .SH "General Methods" .IX Header "General Methods" .IP "encode (\s-1KEYRING\s0)" 4 .IX Item "encode (KEYRING)" Generate the encoded and encrypted form of this token using the provided \&\s-1KEYRING.\s0 The encryption key used will be the one returned by the \&\fBbest_key()\fR method of WebAuth::Keyring on that \s-1KEYRING.\s0 .SH "Accessor Methods" .IX Header "Accessor Methods" .IP "subject ([\s-1SUBJECT\s0])" 4 .IX Item "subject ([SUBJECT])" Get or set the subject, which holds the authenticated identity of the user holding this token. .IP "authz_subject ([\s-1SUBJECT\s0])" 4 .IX Item "authz_subject ([SUBJECT])" Get or set the authorization subject, which holds the asserted authorization identity of the user holding this token. The authorization identity may not match the authenticated identity. It represents a request to use the authorization identity instead of the authentication subject when applying ACLs or determining identity in the application. .IP "last_used ([\s-1TIMESTAMP\s0])" 4 .IX Item "last_used ([TIMESTAMP])" Get or set the last-used timestamp in seconds since epoch, which is updated each time the token is presented to the WebAuth Application Server. This is used to implement inactivity timeouts. .IP "session_key ([\s-1DATA\s0])" 4 .IX Item "session_key ([DATA])" Get or set the session key for communication with the WebKDC. An app token containing a session key is used to allow any system in a pool of WebAuth Application Servers sharing the same private key can decrypt this app token and then use the key to decrypt the tokens returned from the WebKDC. The data contained in this attribute is only the raw key material, not a WebAuth::Key object. .Sp If this attribute is present, none of the other attributes will be present. .IP "initial_factors ([\s-1FACTORS\s0])" 4 .IX Item "initial_factors ([FACTORS])" Get or set a comma-separated list of authentication factors used by the user during initial authentication (the single sign-on transaction). For a list of possible factors and their meaning, see the WebAuth protocol specification. .IP "session_factors ([\s-1FACTORS\s0])" 4 .IX Item "session_factors ([FACTORS])" Get or set a comma-separated list of authentication factors used by the user to authenticate this session (this particular visit to this WebAuth Application Server). For a list of possible factors and their meaning, see the WebAuth protocol specification. .IP "loa ([\s-1LOA\s0])" 4 .IX Item "loa ([LOA])" Get or set the level of assurance established for this user authentication. This is a number whose values are site-defined but for which increasing numbers represent increasing assurance for the authentication. .IP "creation ([\s-1TIMESTAMP\s0])" 4 .IX 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. .IP "expiration ([\s-1TIMESTAMP\s0])" 4 .IX Item "expiration ([TIMESTAMP])" Get or set the expiration timestamp for this token in seconds since epoch. .SH "AUTHOR" .IX Header "AUTHOR" Russ Allbery .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBWebAuth\fR\|(3), \fBWebAuth::Keyring\fR\|(3), \fBWebAuth::Token\fR\|(3) .PP This module is part of WebAuth.
