.SH "DESCRIPTION"

|
|
.IX Header "DESCRIPTION"
|
||
|
|
This command is a basic Time Stamping Authority (\s-1TSA\s0) client and
|
||
|
|
server application as specified in \s-1RFC 3161 \s0(Time-Stamp Protocol, \s-1TSP\s0). A
|
||
|
|
\&\s-1TSA\s0 can be part of a \s-1PKI\s0 deployment and its role is to provide long
|
||
|
|
term proof of the existence of a certain datum before a particular
|
||
|
|
time. Here is a brief description of the protocol:
|
||
|
|
.IP "1." 4
|
||
|
|
The \s-1TSA\s0 client computes a one-way hash value for a data file and sends
|
||
|
|
the hash to the \s-1TSA.\s0
|
||
|
|
.IP "2." 4
|
||
|
|
The \s-1TSA\s0 attaches the current date and time to the received hash value,
|
||
|
|
signs them and sends the timestamp token back to the client. By
|
||
|
|
creating this token the \s-1TSA\s0 certifies the existence of the original
|
||
|
|
data file at the time of response generation.
|
||
|
|
.IP "3." 4
|
||
|
|
The \s-1TSA\s0 client receives the timestamp token and verifies the
|
||
|
|
signature on it. It also checks if the token contains the same hash
|
||
|
|
value that it had sent to the \s-1TSA.\s0
|
||
|
|
.PP
|
||
|
|
There is one \s-1DER\s0 encoded protocol data unit defined for transporting a
|
||
|
|
timestamp request to the \s-1TSA\s0 and one for sending the timestamp response
|
||
|
|
back to the client. This command has three main functions:
|
||
|
|
creating a timestamp request based on a data file,
|
||
|
|
creating a timestamp response based on a request, verifying if a
|
||
|
|
response corresponds to a particular request or a data file.
|
||
|
|
.PP
|
||
|
|
There is no support for sending the requests/responses automatically
|
||
|
|
over \s-1HTTP\s0 or \s-1TCP\s0 yet as suggested in \s-1RFC 3161.\s0 The users must send the
|
||
|
|
requests either by ftp or e\-mail.

||
|

.IX Header "OPTIONS"
|

|
|
.IP "\fB\-help\fR" 4
|
||
|
|

|

|
|

|

|
||
|
|
The \fB\-query\fR command can be used for creating and printing a timestamp
|
||
|
|
request with the following options:
|
||
|
|
.IP "\fB\-config\fR \fIconfigfile\fR" 4
|
||
|
|
.IX Item "-config configfile"
|
||
|
|
The configuration file to use.
|
||
|
|
Optional; for a description of the default value,
|
||
|
|
see \*(L"\s-1COMMAND SUMMARY\*(R"\s0 in \fIopenssl\fR\|(1).
|
||
|
|
.IP "\fB\-data\fR \fIfile_to_hash\fR" 4
|
||
|
|
.IX Item "-data file_to_hash"
|
||
|
|
The data file for which the timestamp request needs to be
|
||
|
|
created. stdin is the default if neither the \fB\-data\fR nor the \fB\-digest\fR
|
||
|
|
parameter is specified. (Optional)
|
||
|
|
.IP "\fB\-digest\fR \fIdigest_bytes\fR" 4
|
||
|
|
.IX Item "-digest digest_bytes"
|
||
|
|
It is possible to specify the message imprint explicitly without the data
|
||
|
|
file. The imprint must be specified in a hexadecimal format, two characters
|
||
|
|
per byte, the bytes optionally separated by colons (e.g. 1A:F6:01:... or
|
||
|
|
1AF601...). The number of bytes must match the message digest algorithm
|
||
|
|
in use. (Optional)
|
||
|
|
.IP "\fB\-\f(BIdigest\fB\fR" 4
|
||
|
|
.IX Item "-digest"
|
||
|
|
The message digest to apply to the data file.
|
||
|
|
Any digest supported by the \fIopenssl\-dgst\fR\|(1) command can be used.
|
||
|
|
The default is \s-1SHA\-256. \s0(Optional)
|
||
|
|
.IP "\fB\-tspolicy\fR \fIobject_id\fR" 4
|
||
|
|
.IX Item "-tspolicy object_id"
|
||
|
|
The policy that the client expects the \s-1TSA\s0 to use for creating the
|
||
|
|
timestamp token. Either the dotted \s-1OID\s0 notation or \s-1OID\s0 names defined
|
||
|
|
in the config file can be used. If no policy is requested the \s-1TSA\s0 will
|
||
|
|
use its own default policy. (Optional)
|
||
|
|

A timestamp response (TimeStampResp) consists of a response status
|
||
|
|
and the timestamp token itself (ContentInfo), if the token generation was
|
||
|
|
successful. The \fB\-reply\fR command is for creating a timestamp
|
||
|
|
response or timestamp token based on a request and printing the
|
||
|
|
response/token in human-readable format. If \fB\-token_out\fR is not
|
||
|
|
specified the output is always a timestamp response (TimeStampResp),
|

No support for timestamps over \s-1SMTP,\s0 though it is quite easy

and \fIperl\fR\|(1). \s-1HTTP\s0 server support is provided in the form of

a separate apache module. \s-1HTTP\s0 client support is provided by

The file containing the last serial number of the \s-1TSA\s0 is not

locked when being read or written. This is a problem if more than one

instance of \fIopenssl\fR\|(1) is trying to create a timestamp
|

response at the same time. This is not an issue when using the apache

server module, it does proper locking.

OpenSSL 1.1.1 introduced a new random generator (\s-1CSPRNG\s0) with an improved

seeding mechanism. The new seeding mechanism makes it unnecessary to

define a \s-1RANDFILE\s0 for saving and restoring randomness. This option is

retained mainly for compatibility reasons.
