Privacy Aware Block Chain Logging
RFC3161 PKI TimeStamp Service
How to test it?
RFC3161 was originaly slated for use with MSFT Authenticode.
Anything that can handle the cryptographic primitives had HTTP Transport will work
Here we weill use OpenSSL to generate a TSP Request and parse the repponse
simply to test the servlet...
- Create the file you will want to timestamp
$ touch inputfile.txt
$ cat aasdfasdf >> inputfile.txt ^^ This is my test file.
- Generate a timestamp request
$ openssl ts -query -data inputfile.txt -cert -sha256 -no_nonce -out request.tsq
- Send the request to your timestamp server
$ curl -k -H "Content-Type: application/timestamp-query" -H Host:timestamp.globalsign.com -d @request.tsq "http://timestamp.globalsign.com"
- Verify the timestamp response
$ openssl ts -reply -in inputfile.txt.tsr -text
This is going to give you some output that looks something like this:
