SESS_ID(1)			    OpenSSL			    SESS_ID(1)

NAME
       sess_id - SSL/TLS session handling utility

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 ses‐
       sion 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 addi‐
	   tional 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 informa‐
	   tion 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
	    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.

       Protocol
	   this is the protocol in use TLSv1, SSLv3 or SSLv2.

       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 stan‐
	   dard 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.
