NAME
openssl-tsget, tsget - Time Stamping HTTP/HTTPS client
SYNOPSIS
tsget -h server_url [-e extension] [-o output] [-v] [-d] [-k private_key.pem] [-p key_password] [-c
client_cert.pem] [-C CA_certs.pem] [-P CA_path] [-r file:file...] [-g EGD_socket] [request]...
DESCRIPTION
The tsget command can be used for sending a time stamp request, as specified in RFC 3161, to a time stamp
server over HTTP or HTTPS and storing the time stamp response in a file. This tool cannot be used for
creating the requests and verifying responses, you can use the OpenSSL ts(1) command to do that. tsget
can send several requests to the server without closing the TCP connection if more than one requests are
specified on the command line.
The tool sends the following HTTP request for each time stamp request:
POST url HTTP/1.1
User-Agent: OpenTSA tsget.pl/<version>
Host: <host>:<port>
Pragma: no-cache
Content-Type: application/timestamp-query
Accept: application/timestamp-reply
Content-Length: length of body
...binary request specified by the user...
tsget expects a response of type application/timestamp-reply, which is written to a file without any
interpretation.
OPTIONS
-h server_url
The URL of the HTTP/HTTPS server listening for time stamp requests.
-e extension
If the -o option is not given this argument specifies the extension of the output files. The base
name of the output file will be the same as those of the input files. Default extension is '.tsr'.
(Optional)
-o output
This option can be specified only when just one request is sent to the server. The time stamp
response will be written to the given output file. '-' means standard output. In case of multiple
time stamp requests or the absence of this argument the names of the output files will be derived
from the names of the input files and the default or specified extension argument. (Optional)
-v The name of the currently processed request is printed on standard error. (Optional)
-d Switches on verbose mode for the underlying curl library. You can see detailed debug messages for the
connection. (Optional)
-k private_key.pem
(HTTPS) In case of certificate-based client authentication over HTTPS <private_key.pem> must contain
the private key of the user. The private key file can optionally be protected by a passphrase. The -c
option must also be specified. (Optional)
-p key_password
(HTTPS) Specifies the passphrase for the private key specified by the -k argument. If this option is
omitted and the key is passphrase protected tsget will ask for it. (Optional)
-c client_cert.pem
(HTTPS) In case of certificate-based client authentication over HTTPS <client_cert.pem> must contain
the X.509 certificate of the user. The -k option must also be specified. If this option is not
specified no certificate-based client authentication will take place. (Optional)
-C CA_certs.pem
(HTTPS) The trusted CA certificate store. The certificate chain of the peer's certificate must
include one of the CA certificates specified in this file. Either option -C or option -P must be
given in case of HTTPS. (Optional)
-P CA_path
(HTTPS) The path containing the trusted CA certificates to verify the peer's certificate. The
directory must be prepared with the c_rehash OpenSSL utility. Either option -C or option -P must be
given in case of HTTPS. (Optional)
-rand file:file...
The files containing random data for seeding the random number generator. Multiple files can be
specified, the separator is ; for MS-Windows, , for VMS and : for all other platforms. (Optional)
-g EGD_socket
The name of an EGD socket to get random data from. (Optional)
[request]...
List of files containing RFC 3161 DER-encoded time stamp requests. If no requests are specified only
one request will be sent to the server and it will be read from the standard input. (Optional)
ENVIRONMENT VARIABLES
The TSGET environment variable can optionally contain default arguments. The content of this variable is
added to the list of command line arguments.
EXAMPLES
The examples below presume that file1.tsq and file2.tsq contain valid time stamp requests,
tsa.opentsa.org listens at port 8080 for HTTP requests and at port 8443 for HTTPS requests, the TSA
service is available at the /tsa absolute path.
Get a time stamp response for file1.tsq over HTTP, output is written to file1.tsr:
tsget -h http://tsa.opentsa.org:8080/tsa file1.tsq
Get a time stamp response for file1.tsq and file2.tsq over HTTP showing progress, output is written to
file1.reply and file2.reply respectively:
tsget -h http://tsa.opentsa.org:8080/tsa -v -e .reply \
file1.tsq file2.tsq
Create a time stamp request, write it to file3.tsq, send it to the server and write the response to
file3.tsr:
openssl ts -query -data file3.txt -cert | tee file3.tsq \
| tsget -h http://tsa.opentsa.org:8080/tsa \
-o file3.tsr
Get a time stamp response for file1.tsq over HTTPS without client authentication:
tsget -h https://tsa.opentsa.org:8443/tsa \
-C cacerts.pem file1.tsq
Get a time stamp response for file1.tsq over HTTPS with certificate-based client authentication (it will
ask for the passphrase if client_key.pem is protected):
tsget -h https://tsa.opentsa.org:8443/tsa -C cacerts.pem \
-k client_key.pem -c client_cert.pem file1.tsq
You can shorten the previous command line if you make use of the TSGET environment variable. The
following commands do the same as the previous example:
TSGET='-h https://tsa.opentsa.org:8443/tsa -C cacerts.pem \
-k client_key.pem -c client_cert.pem'
export TSGET
tsget file1.tsq
