9 tsget -h server_url [-e extension] [-o output] [-v] [-d] [-k
10 private_key.pem] [-p key_password] [-c client_cert.pem] [-C
11 CA_certs.pem] [-P CA_path] [-r file:file...] [-g EGD_socket]

15 The tsget command can be used for sending a time stamp request, as
16 specified in RFC 3161, to a time stamp server over HTTP or HTTPS and
17 storing the time stamp response in a file. This tool cannot be used for
18 creating the requests and verifying responses, you can use the OpenSSL
19 ts(1) command to do that. tsget can send several requests to the server
20 without closing the TCP connection if more than one requests are
21 specified on the command line.
22 The tool sends the following HTTP request for each time stamp request:
24 POST url HTTP/1.1
26 User-Agent: OpenTSA tsget.pl/<version>
27 Host: <host>:<port>
28 Pragma: no-cache
29 Content-Type: application/timestamp-query
30 Accept: application/timestamp-reply
31 Content-Length: length of body
32 ...binary request specified by the user...
34 tsget expects a response of type application/timestamp-reply, which is
36 written to a file without any interpretation.
37
39 -h server_url
40 The URL of the HTTP/HTTPS server listening for time stamp requests.
41 -e extension
43 If the -o option is not given this argument specifies the extension
44 of the output files. The base name of the output file will be the
45 same as those of the input files. Default extension is '.tsr'.
46 (Optional)
47 -o output
49 This option can be specified only when just one request is sent to
50 the server. The time stamp response will be written to the given
51 output file. '-' means standard output. In case of multiple time
52 stamp requests or the absence of this argument the names of the
53 output files will be derived from the names of the input files and
54 the default or specified extension argument. (Optional)
55 -v The name of the currently processed request is printed on standard
57 error. (Optional)
58 -d Switches on verbose mode for the underlying curl library. You can
60 see detailed debug messages for the connection. (Optional)
61 -k private_key.pem
63 (HTTPS) In case of certificate-based client authentication over
64 HTTPS <private_key.pem> must contain the private key of the user.
65 The private key file can optionally be protected by a passphrase.
66 The -c option must also be specified. (Optional)
67 -p key_password
69 (HTTPS) Specifies the passphrase for the private key specified by
70 the -k argument. If this option is omitted and the key is
71 passphrase protected tsget will ask for it. (Optional)
72 -c client_cert.pem
74 (HTTPS) In case of certificate-based client authentication over
75 HTTPS <client_cert.pem> must contain the X.509 certificate of the
76 user. The -k option must also be specified. If this option is not
77 specified no certificate-based client authentication will take
78 place. (Optional)
79 -C CA_certs.pem
81 (HTTPS) The trusted CA certificate store. The certificate chain of
82 the peer's certificate must include one of the CA certificates
83 specified in this file. Either option -C or option -P must be
84 given in case of HTTPS. (Optional)
85 -P CA_path
87 (HTTPS) The path containing the trusted CA certificates to verify
88 the peer's certificate. The directory must be prepared with the
89 c_rehash OpenSSL utility. Either option -C or option -P must be
90 given in case of HTTPS. (Optional)
91 -rand file:file...
93 The files containing random data for seeding the random number
94 generator. Multiple files can be specified, the separator is ; for
95 MS-Windows, , for VMS and : for all other platforms. (Optional)
96 -g EGD_socket
98 The name of an EGD socket to get random data from. (Optional)
99 [request]...
101 List of files containing RFC 3161 DER-encoded time stamp requests.
102 If no requests are specified only one request will be sent to the
103 server and it will be read from the standard input. (Optional)
104
106 The TSGET environment variable can optionally contain default
107 arguments. The content of this variable is added to the list of command
108 line arguments.
109
111 The examples below presume that file1.tsq and file2.tsq contain valid
112 time stamp requests, tsa.opentsa.org listens at port 8080 for HTTP
113 requests and at port 8443 for HTTPS requests, the TSA service is
114 available at the /tsa absolute path.
115 Get a time stamp response for file1.tsq over HTTP, output is written to
117 file1.tsr:
118 tsget -h http://tsa.opentsa.org:8080/tsa file1.tsq
120 Get a time stamp response for file1.tsq and file2.tsq over HTTP showing
122 progress, output is written to file1.reply and file2.reply
123 respectively:
124 tsget -h http://tsa.opentsa.org:8080/tsa -v -e .reply \
126 file1.tsq file2.tsq
127 Create a time stamp request, write it to file3.tsq, send it to the
129 server and write the response to file3.tsr:
130 openssl ts -query -data file3.txt -cert | tee file3.tsq \
132 | tsget -h http://tsa.opentsa.org:8080/tsa \
133 -o file3.tsr
134 Get a time stamp response for file1.tsq over HTTPS without client
136 authentication:
137 tsget -h https://tsa.opentsa.org:8443/tsa \
139 -C cacerts.pem file1.tsq
140 Get a time stamp response for file1.tsq over HTTPS with certificate-
142 based client authentication (it will ask for the passphrase if
143 client_key.pem is protected):
144 tsget -h https://tsa.opentsa.org:8443/tsa -C cacerts.pem \
146 -k client_key.pem -c client_cert.pem file1.tsq
147 You can shorten the previous command line if you make use of the TSGET
149 environment variable. The following commands do the same as the
150 previous example:
151 TSGET='-h https://tsa.opentsa.org:8443/tsa -C cacerts.pem \
153 -k client_key.pem -c client_cert.pem'
154 export TSGET
155 tsget file1.tsq
