 |  | 
 | =head1 DESCRIPTION | 
 |  | 
 | The B<tsget> command can be used for sending a timestamp request, as | 
 | specified in B<RFC 3161>, to a timestamp server over HTTP or HTTPS and storing | 
 | the timestamp response in a file. 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 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... | 
 |  | 
 | 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 timestamp 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 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) | 
 |  | 
 | =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 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) | 
 |  | 
 | =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 | 
 | 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 B<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 |
