+=head1 DESCRIPTION
+
+The B<ts> command is a basic Time Stamping Authority (TSA) client and server
+application as specified in RFC 3161 (Time-Stamp Protocol, TSP). A
+TSA can be part of a PKI deployment and its role is to provide long
+term proof of the existence of a certain datum before a particular
+time. Here is a brief description of the protocol:
+
+=over 4
+
+=item 1.
+
+The TSA client computes a one-way hash value for a data file and sends
+the hash to the TSA.
+
+=item 2.
+
+The TSA attaches the current date and time to the received hash value,
+signs them and sends the time stamp token back to the client. By
+creating this token the TSA certifies the existence of the original
+data file at the time of response generation.
+
+=item 3.
+
+The TSA client receives the time stamp token and verifies the
+signature on it. It also checks if the token contains the same hash
+value that it had sent to the TSA.
+
+=back
+
+There is one DER encoded protocol data unit defined for transporting a time
+stamp request to the TSA and one for sending the time stamp response
+back to the client. The B<ts> command has three main functions:
+creating a time stamp request based on a data file,
+creating a time stamp response based on a request, verifying if a
+response corresponds to a particular request or a data file.
+
+There is no support for sending the requests/responses automatically
+over HTTP or TCP yet as suggested in RFC 3161. The users must send the
+requests either by ftp or e-mail.
+
+=head1 OPTIONS
+
+=head2 Time Stamp Request generation
+
+The B<-query> switch can be used for creating and printing a time stamp
+request with the following options:
+
+=over 4
+
+=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<-config> configfile
+
+The configuration file to use, this option overrides the
+B<OPENSSL_CONF> environment variable. Only the OID section
+of the config file is used with the B<-query> command. (Optional)
+
+=item B<-data> file_to_hash
+
+The data file for which the time stamp request needs to be
+created. stdin is the default if neither the B<-data> nor the B<-digest>
+parameter is specified. (Optional)
+
+=item B<-digest> digest_bytes
+
+It is possible to specify the message imprint explicitly without the data
+file. The imprint must be specified in a hexadecimal format, two characters
+per byte, the bytes optionally separated by colons (e.g. 1A:F6:01:... or
+1AF601...). The number of bytes must match the message digest algorithm 
+in use. (Optional)
+
+=item B<-md2>|B<-md4>|B<-md5>|B<-sha>|B<-sha1>|B<-mdc2>|B<-ripemd160>
+
+The message digest to apply to the data file. The default is SHA-1. (Optional)
+
+=item B<-policy> object_id
+
+The policy that the client expects the TSA to use for creating the
+time stamp token. Either the dotted OID notation or OID names defined
+in the config file can be used. If no policy is requested the TSA will
+use its own default policy. (Optional)
+
+=item B<-no_nonce>
+
+No nonce is specified in the request if this option is
+given. Otherwise a 64 bit long pseudo-random none is
+included in the request. It is recommended to use nonce to
+protect against replay-attacks. (Optional)
+
+=item B<-cert>
+
+The TSA is expected to include its signing certificate in the
+response. (Optional)
+
+=item B<-in> request.tsq
+
+This option specifies a previously created time stamp request in DER
+format that will be printed into the output file. Useful when you need
+to examine the content of a request in human-readable
+
+format. (Optional)
+
+=item B<-out> request.tsq
+
+Name of the output file to which the request will be written. Default
+is stdout. (Optional)
+
+=item B<-text>
+
+If this option is specified the output is human-readable text format
+instead of DER. (Optional)
+
+=back
+
+=head2 Time Stamp Response generation
+
+A time stamp response (TimeStampResp) consists of a response status
+and the time stamp token itself (ContentInfo), if the token generation was
+successful. The B<-reply> command is for creating a time stamp
+response or time stamp token based on a request and printing the
+response/token in human-readable format. If B<-token_out> is not
+specified the output is always a time stamp response (TimeStampResp),
+otherwise it is a time stamp token (ContentInfo).
+
+=over 4
+
+=item B<-config> configfile
+
+The configuration file to use, this option overrides the
+B<OPENSSL_CONF> environment variable. See B<CONFIGURATION FILE
+OPTIONS> for configurable variables. (Optional)
+
+=item B<-section> tsa_section
+
+The name of the config file section conatining the settings for the
+response generation. If not specified the default TSA section is
+used, see B<CONFIGURATION FILE OPTIONS> for details. (Optional)
+
+=item B<-queryfile> request.tsq
+
+The name of the file containing a DER encoded time stamp request. (Optional)
+
+=item B<-passin> password_src
+
+Specifies the password source for the private key of the TSA. See
+B<PASS PHRASE ARGUMENTS> in L<openssl(1)|openssl(1)>. (Optional)
+
+=item B<-signer> tsa_cert.pem
+
+The signer certificate of the TSA in PEM format. The TSA signing
+certificate must have exactly one extended key usage assigned to it:
+timeStamping. The extended key usage must also be critical, otherwise
+the certificate is going to be refused. Overrides the B<signer_cert>
+variable of the config file. (Optional)
+
+=item B<-inkey> private.pem
+
+The signer private key of the TSA in PEM format. Overrides the
+B<signer_key> config file option. (Optional)
+
+=item B<-chain> certs_file.pem
+
+The collection of certificates in PEM format that will all
+be included in the response in addition to the signer certificate if
+the B<-cert> option was used for the request. This file is supposed to
+contain the certificate chain for the signer certificate from its
+issuer upwards. The B<-reply> command does not build a certificate
+chain automatically. (Optional)
+
+=item B<-policy> object_id
+
+The default policy to use for the response unless the client
+explicitly requires a particular TSA policy. The OID can be specified
+either in dotted notation or with its name. Overrides the
+B<default_policy> config file option. (Optional)
+
+=item B<-in> response.tsr
+
+Specifies a previously created time stamp response or time stamp token
+(if B<-token_in> is also specified) in DER format that will be written
+to the output file. This option does not require a request, it is
+useful e.g. when you need to examine the content of a response or
+token or you want to extract the time stamp token from a response. If
+the input is a token and the output is a time stamp response a default
+'granted' status info is added to the token. (Optional)
+
+=item B<-token_in>
+
+This flag can be used together with the B<-in> option and indicates
+that the input is a DER encoded time stamp token (ContentInfo) instead
+of a time stamp response (TimeStampResp). (Optional)
+
+=item B<-out> response.tsr
+
+The response is written to this file. The format and content of the
+file depends on other options (see B<-text>, B<-token_out>). The default is
+stdout. (Optional)
+
+=item B<-token_out>
+
+The output is a time stamp token (ContentInfo) instead of time stamp
+response (TimeStampResp). (Optional)
+
+=item B<-text>
+
+If this option is specified the output is human-readable text format
+instead of DER. (Optional)
+
+=item B<-engine> id
+
+Specifying an engine (by it's unique B<id> string) will cause B<ts>
+to attempt to obtain a functional reference to the specified engine,
+thus initialising it if needed. The engine will then be set as the default
+for all available algorithms. Default is builtin. (Optional)
+
+=back
+
+=head2 Time Stamp Response verification
+
+The B<-verify> command is for verifying if a time stamp response or time
+stamp token is valid and matches a particular time stamp request or
+data file. The B<-verify> command does not use the configuration file.
+
+=over 4
+
+=item B<-data> file_to_hash
+
+The response or token must be verified against file_to_hash. The file
+is hashed with the message digest algorithm specified in the token. 
+The B<-digest> and B<-queryfile> options must not be specified with this one.
+(Optional)
+
+=item B<-digest> digest_bytes
+
+The response or token must be verified against the message digest specified
+with this option. The number of bytes must match the message digest algorithm
+specified in the token. The B<-data> and B<-queryfile> options must not be
+specified with this one. (Optional)
+
+=item B<-queryfile> request.tsq
+
+The original time stamp request in DER format. The B<-data> and B<-digest>
+options must not be specified with this one. (Optional)
+

+=head1 CONFIGURATION FILE OPTIONS
+
+The B<-query> and B<-reply> commands make use of a configuration file
+defined by the B<OPENSSL_CONF> environment variable. See L<config(5)|config(5>
+for a general description of the syntax of the config file. The
+B<-query> command uses only the symbolic OID names section
+and it can work without it. However, the B<-reply> command needs the
+config file for its operation.
+
+When there is a command line switch equivalent of a variable the
+switch always overrides the settings in the config file.
+
+=over 4
+
+=item B<tsa> section, B<default_tsa>	
+
+This is the main section and it specifies the name of another section
+that contains all the options for the B<-reply> command. This default
+section can be overriden with the B<-section> command line switch. (Optional)
+

+=item B<clock_precision_digits>
+
+Specifies the maximum number of digits, which represent the fraction of

+or no fraction of seconds at all. Supported only on UNIX platforms.
+The maximum value is 6, default is 0.
+(Optional)
+
+=item B<ordering>
+
+If this option is yes the responses generated by this TSA can always

+
+All the examples below presume that B<OPENSSL_CONF> is set to a proper
+configuration file, e.g. the example configuration file 
+openssl/apps/openssl.cnf will do.
+
+=head2 Time Stamp Request
+
+To create a time stamp request for design1.txt with SHA-1 
+without nonce and policy and no certificate is required in the response:
+
+  openssl ts -query -data design1.txt -no_nonce \
+	-out design1.tsq
+
+To create a similar time stamp request with specifying the message imprint
+explicitly:
+
+  openssl ts -query -digest b7e5d3f93198b38379852f2c04e78d73abdd0f4b \
+	 -no_nonce -out design1.tsq
+
+To print the content of the previous request in human readable format:
+
+  openssl ts -query -in design1.tsq -text
+
+To create a time stamp request which includes the MD-5 digest 
+of design2.txt, requests the signer certificate and nonce,
+specifies a policy id (assuming the tsa_policy1 name is defined in the
+OID section of the config file):
+
+  openssl ts -query -data design2.txt -md5 \
+	-policy tsa_policy1 -cert -out design2.tsq
+
+=head2 Time Stamp Response
+
+Before generating a response a signing certificate must be created for
+the TSA that contains the B<timeStamping> critical extended key usage extension
+without any other key usage extensions. You can add the
+'extendedKeyUsage = critical,timeStamping' line to the user certificate section
+of the config file to generate a proper certificate. See L<req(1)|req(1)>,
+L<ca(1)|ca(1)>, L<x509(1)|x509(1)> for instructions. The examples
+below assume that cacert.pem contains the certificate of the CA,
+tsacert.pem is the signing certificate issued by cacert.pem and
+tsakey.pem is the private key of the TSA.
+
+To create a time stamp response for a request:
+
+  openssl ts -reply -queryfile design1.tsq -inkey tsakey.pem \
+	-signer tsacert.pem -out design1.tsr
+
+If you want to use the settings in the config file you could just write:
+
+  openssl ts -reply -queryfile design1.tsq -out design1.tsr
+
+To print a time stamp reply to stdout in human readable format:
+
+  openssl ts -reply -in design1.tsr -text
+
+To create a time stamp token instead of time stamp response:
+
+  openssl ts -reply -queryfile design1.tsq -out design1_token.der -token_out
+
+To print a time stamp token to stdout in human readable format:
+
+  openssl ts -reply -in design1_token.der -token_in -text -token_out
+
+To extract the time stamp token from a response:
+
+  openssl ts -reply -in design1.tsr -out design1_token.der -token_out
+
+To add 'granted' status info to a time stamp token thereby creating a
+valid response:
+
+  openssl ts -reply -in design1_token.der -token_in -out design1.tsr
+
+=head2 Time Stamp Verification
+
+To verify a time stamp reply against a request:
+
+  openssl ts -verify -queryfile design1.tsq -in design1.tsr \
+	-CAfile cacert.pem -untrusted tsacert.pem
+
+To verify a time stamp reply that includes the certificate chain:
+
+  openssl ts -verify -queryfile design2.tsq -in design2.tsr \
+	-CAfile cacert.pem
+
+To verify a time stamp token against the original data file:
+  openssl ts -verify -data design2.txt -in design2.tsr \
+	-CAfile cacert.pem
+
+To verify a time stamp token against a message imprint:
+  openssl ts -verify -digest b7e5d3f93198b38379852f2c04e78d73abdd0f4b \
+	 -in design2.tsr -CAfile cacert.pem
+
+You could also look at the 'test' directory for more examples.

+=head1 BUGS
+
+If you find any bugs or you have suggestions please write to
+Zoltan Glozik <zglozik@opentsa.org>. Known issues:
+
+=over 4
+
+=item * No support for time stamps over SMTP, though it is quite easy
+to implement an automatic e-mail based TSA with L<procmail(1)|procmail(1)> 
+and L<perl(1)|perl(1)>. HTTP server support is provided in the form of 
+a separate apache module. HTTP client support is provided by
+L<tsget(1)|tsget(1)>. Pure TCP/IP protocol is not supported.
+
+=item * The file containing the last serial number of the TSA is not
+locked when being read or written. This is a problem if more than one
+instance of L<openssl(1)|openssl(1)> is trying to create a time stamp
+response at the same time. This is not an issue when using the apache
+server module, it does proper locking.
+
+=item * Look for the FIXME word in the source files.
+
+=item * The source code should really be reviewed by somebody else, too.
+
+=item * More testing is needed, I have done only some basic tests (see
+test/testtsa).

+[B<-o> output]
+[B<-v>]
+[B<-d>]

+[request]...
+
+=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 specifed 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
