NAME
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 files] [-g EGD_socket] [request ...]
DESCRIPTION
This command can be used for sending a timestamp request, as specified
in RFC 3161, to a timestamp server over HTTP or HTTPS and storing the
timestamp response in a file. It cannot be used for creating the
requests and verifying responses, you have to use openssl-ts(1) to do
that. This command can send several requests to the server without
closing the TCP connection if more than one requests are specified on
the command line.
This command sends the following HTTP request for each timestamp
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...
It 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 timestamp 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 timestamp response will be written to the given
output file. '-' means standard output. In case of multiple
timestamp 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 perl module
WWW::Curl::Easy. 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, it will be prompted for. (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
openssl-rehash(1). Either option -C or option -P must be given in
case of HTTPS. (Optional)
-r files
See "Random State Options" in openssl(1) for more information.
-g EGD_socket
The name of an EGD socket to get random data from. (Optional)
request ...
List of files containing RFC 3161 DER-encoded timestamp 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
timestamp 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 timestamp response for file1.tsq over HTTP, output is written to
file1.tsr:
tsget -h http://tsa.opentsa.org:8080/tsa file1.tsq
Get a timestamp 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 timestamp 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 timestamp response for file1.tsq over HTTPS without client
authentication:
tsget -h https://tsa.opentsa.org:8443/tsa \
-C cacerts.pem file1.tsq
Get a timestamp 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
