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 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
