DESCRIPTIONThe 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.
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. RestrictionsThe cipher and start time should be printed out in human readable
form. SEE ALSOciphers(1) , s_server(1)
