SESID(1)                          OpenSL                         SESID(1)



NAME
       sessid - SL/TLS session handling utility

SYNOPSIS
       openssl sessid [-inform PEMDER] [-outform PEMDER] [-in filename]
       [-out filename] [-text] [-noout] [-context ID]

DESCRIPTION
       The sessid process the encoded version of the SL session structure
       and optionally prints out SL session details (for example the SL ses-
       sion master key) in human readable format. Since this is a diagnostic
       tool that needs some knowledge of the SL protocol to use properly,
       most users will not need to use it.

       -inform DERPEM
           This specifies the input format. The DER option uses an ASN1 DER
           encoded format containing session details. The precise format can
           vary from one version to the next.  The PEM form is the default
           format: it consists of the DER format base64 encoded with addi-
           tional header and footer lines.

       -outform DERPEM
           This specifies the output format, the options have the same meaning
           as the -inform option.

       -in filename
           This specifies the input filename to read session information from
           or standard input by default.

       -out filename
           This specifies the output filename to write session information to
           or standard output if this option is not specified.

       -text
           prints out the various public or private key components in plain
           text in addition to the encoded version.

       -cert
           if a certificate is present in the session it will be output using
           this option, if the -text option is also present then it will be
           printed out in text form.

       -noout
           this option prevents output of the encoded version of the session.

       -context ID
           this option can set the session id so the output session informa-
           tion uses the supplied ID. The ID can be any string of characters.
           This option wont normally be used.

OUTPUT
       Typical output:

        SL-Session:
            Protocol  : TLSv1
            Cipher    : 0016
            Session-ID: 871E62626C554CE95488823752CBD5F3673A3EF3DCE9C67BD916C809914B40ED
            Session-ID-ctx: 01000000
            Master-Key: A7CEFC571974BE02CAC305269DC59F76EA9F0B180CB6642697A68251F2D2B57E51DB4C7885573192AE9AE220FACD
            Key-Arg   : None
            Start Time: 948459261
            Timeout   : 300 (sec)
            Verify return code 0 (ok)

       Theses are described below in more detail.

       Protocol
           this is the protocol in use TLSv1, SLv3 or SLv2.

       Cipher
           the cipher used this is the actual raw SL or TLS cipher code, see
           the SL or TLS specifications for more information.

       Session-ID
           the SL session ID in hex format.

       Session-ID-ctx
           the session ID context in hex format.

       aster-Key
           this is the SL session master key.

       Key-Arg
           the key argument, this is only used in SL v2.

       Start Time
           this is the session start time represented as an integer in stan-
           dard Unix format.

       Timeout
           the timeout in seconds.

       Verify return code
           this is the return code when an SL client certificate is verified.

NOTES
       The PEM encoded session format uses the header and footer lines:

        -----BEGIN SL SESION PARAMETERS-----
        -----END SL SESION PARAMETERS-----

       Since the SL 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.

BUGS
       The cipher and start time should be printed out in human readable form.
