This tool cannot be used for creating the +requests and verifying responses, you can use the OpenSSL B<ts(1)> command to +do that. B<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... + +B<tsget> expects a response of type application/timestamp-reply, which is +written to a file without any interpretation. + +=head1 OPTIONS + +=over 4 + +=item B<-h> server_url + +The URL of the HTTP/HTTPS server listening for time stamp requests. + +=item B<-e> extension + +If the B<-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) + +=item B<-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) + +=item B<-v> + +The name of the currently processed request is printed on standard +error. (Optional) + +=item B<-d> + +Switches on verbose mode for the underlying B<curl> library. You can see +detailed debug messages for the connection. (Optional) + +=item B<-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 B<-c> option must also +be specified. (Optional) + +=item B<-p> key_password + +(HTTPS) Specifies the passphrase for the private key specified by the B<-k> +argument. If this option is omitted and the key is passphrase protected B<tsget> +will ask for it. (Optional) + +=item B<-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 B<-k> +option must also be specified. If this option is not specified no +certificate-based client authentication will take place. (Optional) + +=item B<-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 B<-C> or option B<-P> must be given in case of HTTPS. (Optional) + +=item B<-P> CA_path + +(HTTPS) The path containing the trusted CA certificates to verify the peer's +certificate. The directory must be prepared with the B<c_rehash> +OpenSSL utility. Either option B<-C> or option B<-P> must be given in case of +HTTPS. (Optional) + +=item B<-rand> file:file... + +The files containing random data for seeding the random number +generator. Multiple files can be specified, the separator is B<;> for +MS-Windows, B<,> for VMS and B<:> for all other platforms. (Optional) + +=item B<-g> EGD_socket + +The name of an EGD socket to get random data from. (Optional) + +=item [request]... + +List of files containing B<RFC 3161> DER-encoded time stamp requests. If no +requests are specifed only one request will be sent to the server and it will be +read from the standard input. (Optional) + +=back + +=head1 ENVIRONMENT VARIABLES + +The B<TSGET> environment variable can optionally contain default +arguments. The content of this variable is added to the list of command line +arguments. + +=head1 EXAMPLES + +The examples below presume that B<file1.tsq> and B<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 B<TSGET> +environment variable.
