tsget - Time Stamping HTTP/HTTPS client
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 ...]
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.
- -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)
The TSGET environment variable can optionally contain default arguments.
The content of this variable is added to the list of command line arguments.
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
