sess_id


SYNOPSIS
       openssl sess_id [-inform PEM|DER] [-outform PEM|DER] [-in filename]
       [-out filename] [-text] [-noout] [-context ID]

DESCRIPTION
       The 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.

       -inform DER|PEM
           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
           additional header and footer lines.

       -outform DER|PEM
           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
           information uses the supplied ID. The ID can be any string of
           characters. This option wont normally be used.

OUTPUT
       Typical output:

        SSL-Session:
            Protocol  : TLSv1
            Cipher    : 0016

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

       Session-ID
           the SSL session ID in hex format.

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

       Master-Key
           this is the SSL session master key.

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

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

       Timeout
           the timeout in seconds.

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

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.

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