+
+sess_id - SSL/TLS session handling utility
+
+=head1 SYNOPSIS
+
+B<openssl> B<sess_id>
+[B<-inform PEM|DER>]
+[B<-outform PEM|DER>]
+[B<-in filename>]
+[B<-out filename>]
+[B<-text>]
+[B<-noout>]
+[B<-context ID>]
+
+=head1 DESCRIPTION
+
+The B<sess_id> process the encoded version of the SSL session structure
+and optionally prints out SSL session details (for example the SSL session
+master key) in human readable format. Since this is a diagnostic tool that
+needs some knowledge of the SSL protocol to use properly, most users will
+not need to use it.
+
+=over 4
+
+=item B<-inform DER|PEM>
+
+This specifies the input format. The B<DER> option uses an ASN1 DER encoded
+format containing session details. The precise format can vary from one version
+to the next. The B<PEM> form is the default format: it consists of the B<DER>
+format base64 encoded with additional header and footer lines.
+
+=item B<-outform DER|PEM>
+
+This specifies the output format, the options have the same meaning as the
+B<-inform> option.
+
+=item B<-in filename>
+
+This specifies the input filename to read session information from or standard
+input by default.
+
+=item B<-out filename>
+
+This specifies the output filename to write session information toor standard
+output if this option is not specified.
+
+=item B<-text>
+
+prints out the various public or private key components in
+plain text in addition to the encoded version.
+
+=item B<-cert>
+
+if a certificate is present in the session it will be output using this option,
+if the B<-text> option is also present then it will be printed out in text form.
+
+=item B<-noout>
+
+this option prevents output of the encoded version of the session.
+
+=item B<-context ID>
+
+this option can set the session id so the output session information uses the
+supplied ID. The ID can be any string of characters. This option wont normally
+be used.

+
+Typical output:
+
+ SSL-Session:
+ Protocol : TLSv1
+ Cipher : 0016
+ Session-ID: 871E62626C554CE95488823752CBD5F3673A3EF3DCE9C67BD916C809914B40ED
+ Session-ID-ctx: 01000000
+ Master-Key: A7CEFC571974BE02CAC305269DC59F76EA9F0B180CB6642697A68251F2D2BB57E51DBBB4C7885573192AE9AEE220FACD
+ Key-Arg : None
+ Start Time: 948459261
+ Timeout : 300 (sec)
+ Verify return code 0 (ok)
+
+Theses are described below in more detail.
+
+=over 4
+
+=item B<Protocol>
+
+this is the protocol in use TLSv1, SSLv3 or SSLv2.
+
+=item B<Cipher>
+
+the cipher used this is the actual raw SSL or TLS cipher code, see the SSL
+or TLS specifications for more information.
+
+=item B<Session-ID>
+
+the SSL session ID in hex format.
+
+=item B<Session-ID-ctx>
+
+the session ID context in hex format.
+
+=item B<Master-Key>
+
+this is the SSL session master key.
+
+=item B<Key-Arg>
+
+the key argument, this is only used in SSL v2.
+
+=item B<Start Time>
+
+this is the session start time represented as an integer in standard Unix format.
+
+=item B<Timeout>
+
+the timeout in seconds.
+
+=item B<Verify return code>
+
+this is the return code when an SSL client certificate is verified.
+

+
+=head1 NOTES
+
+The PEM encoded session format uses the header and footer lines:
+
+ -----BEGIN SSL SESSION PARAMETERS-----
+ -----END SSL SESSION PARAMETERS-----
+
+Since the SSL session output contains the master key it is possible to read the contents
+of an encrypted session using this information. Therefore appropriate security precautions
+should be taken if the information is being output by a "real" application. This is
+however strongly discouraged and should only be used for debugging purposes.
+
+=head1 BUGS
+
+The cipher and start time should be printed out in human readable form.
