TSGET(1SSL)                                    OpenSSL                                   TSGET(1SSL)

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 files] [-g EGD_socket]
       [request ...]

DESCRIPTION
       This command can be used for sending a timestamp request, as specified in RFC 3161, to a
       timestamp server over HTTP or HTTPS and storing the timestamp response in a file. It cannot
       be used for creating the requests and verifying responses, you have to use openssl-ts(1) to
       do that. This command can send several requests to the server without closing the TCP
       connection if more than one requests are specified on the command line.

       This command 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...

       It 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 timestamp 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
           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)

       -v  The name of the currently processed request is printed on standard error. (Optional)

       -d  Switches  on  verbose  mode  for the underlying perl module WWW::Curl::Easy.  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, it will be prompted for.
           (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 openssl-rehash(1). Either option -C or option -P must
           be given in case of HTTPS. (Optional)

       -r files
           See "Random State Options" in openssl(1) for more information.

       -g EGD_socket
           The name of an EGD socket to get random data from. (Optional)

       request ...
           List  of  files  containing  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)

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  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 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
