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]...
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...
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
