6 tsget - Time Stamping HTTP/HTTPS client
7
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 files] [-g EGD_socket] [request ...]
12
14 This command can be used for sending a timestamp request, as specified
15 in RFC 3161, to a timestamp server over HTTP or HTTPS and storing the
16 timestamp response in a file. It cannot be used for creating the
17 requests and verifying responses, you have to use openssl-ts(1) to do
18 that. This command can send several requests to the server without
19 closing the TCP connection if more than one requests are specified on
20 the command line.
21 This command sends the following HTTP request for each timestamp
23 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 It 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 timestamp 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 timestamp response will be written to the given
51 output file. '-' means standard output. In case of multiple
52 timestamp 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 perl module
60 WWW::Curl::Easy. You can see detailed debug messages for the
61 connection. (Optional)
62 -k private_key.pem
64 (HTTPS) In case of certificate-based client authentication over
65 HTTPS private_key.pem must contain the private key of the user. The
66 private key file can optionally be protected by a passphrase. The
67 -c option must also be specified. (Optional)
68 -p key_password
70 (HTTPS) Specifies the passphrase for the private key specified by
71 the -k argument. If this option is omitted and the key is
72 passphrase protected, it will be prompted for. (Optional)
73 -c client_cert.pem
75 (HTTPS) In case of certificate-based client authentication over
76 HTTPS client_cert.pem must contain the X.509 certificate of the
77 user. The -k option must also be specified. If this option is not
78 specified no certificate-based client authentication will take
79 place. (Optional)
80 -C CA_certs.pem
82 (HTTPS) The trusted CA certificate store. The certificate chain of
83 the peer's certificate must include one of the CA certificates
84 specified in this file. Either option -C or option -P must be
85 given in case of HTTPS. (Optional)
86 -P CA_path
88 (HTTPS) The path containing the trusted CA certificates to verify
89 the peer's certificate. The directory must be prepared with
90 openssl-rehash(1). Either option -C or option -P must be given in
91 case of HTTPS. (Optional)
92 -r files
94 See "Random State Options" in openssl(1) for more information.
95 -g EGD_socket
97 The name of an EGD socket to get random data from. (Optional)
98 request ...
100 List of files containing RFC 3161 DER-encoded timestamp requests.
101 If no requests are specified only one request will be sent to the
102 server and it will be read from the standard input. (Optional)
103
105 The TSGET environment variable can optionally contain default
106 arguments. The content of this variable is added to the list of command
107 line arguments.
108
110 The examples below presume that file1.tsq and file2.tsq contain valid
111 timestamp requests, tsa.opentsa.org listens at port 8080 for HTTP
112 requests and at port 8443 for HTTPS requests, the TSA service is
113 available at the /tsa absolute path.
114 Get a timestamp response for file1.tsq over HTTP, output is written to
116 file1.tsr:
117 tsget -h http://tsa.opentsa.org:8080/tsa file1.tsq
119 Get a timestamp response for file1.tsq and file2.tsq over HTTP showing
121 progress, output is written to file1.reply and file2.reply
122 respectively:
123 tsget -h http://tsa.opentsa.org:8080/tsa -v -e .reply \
125 file1.tsq file2.tsq
126 Create a timestamp request, write it to file3.tsq, send it to the
128 server and write the response to file3.tsr:
129 openssl ts -query -data file3.txt -cert | tee file3.tsq \
131 | tsget -h http://tsa.opentsa.org:8080/tsa \
132 -o file3.tsr
133 Get a timestamp response for file1.tsq over HTTPS without client
135 authentication:
136 tsget -h https://tsa.opentsa.org:8443/tsa \
138 -C cacerts.pem file1.tsq
139 Get a timestamp response for file1.tsq over HTTPS with certificate-
141 based client authentication (it will ask for the passphrase if
142 client_key.pem is protected):
143 tsget -h https://tsa.opentsa.org:8443/tsa -C cacerts.pem \
145 -k client_key.pem -c client_cert.pem file1.tsq
146 You can shorten the previous command line if you make use of the TSGET
148 environment variable. The following commands do the same as the
149 previous example:
150 TSGET='-h https://tsa.opentsa.org:8443/tsa -C cacerts.pem \
152 -k client_key.pem -c client_cert.pem'
153 export TSGET
154 tsget file1.tsq
