| |
| =head1 DESCRIPTION |
| |
| The B<tsget> command can be used for sending a time stamp request, as |
| specified in B<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 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 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 |
| 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. 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 |
