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
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
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
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.
