Does anyone know a free(trial) timestamp server service? [closed]

Question

Would like to know if anybody knows any free(trial) time-stamp server service. I would like to test time stamping features in itext. Like I used Start Com class 1 as free CA for testing purposes. Hope I made it clear. Hoping someone knows a place Thanks

Questions asking us to recommend or find a tool, library or favorite off-site resource are off-topic for Stack Overflow as they tend to attract opinionated answers and spam. Instead, describe the problem and what has been done so far to solve it. – Broomfield

Like tsa.safecreative.org ? – Shipyard

great.... exactly what I wanted, plus i could certify. thanks a lot Konstantin !! – Puss

Answer 1

You can try one of these publicly accessible RFC 3161 compliant time-stamping services:

1. https://freetsa.org
   Supports HTTP, HTTPS and TCP transports and has other features
2. http://time.certum.pl
3. http://zeitstempel.dfn.de
4. http://tsa.tecxoft.com
   Requires registration & paid
5. http://timestamp.sectigo.com
   (formerly http://timestamp.comodoca.com/rfc3161)
6. http://sha256timestamp.ws.symantec.com/sha256/timestamp
7. https://ca.signfiles.com/tsa/get.aspx
   Still active, but the configuration panel for the CA is wide open. I'd recommend against using it, as anyone can remove your access anytime.
8. https://tsp.iaik.tugraz.at/tsp/TspRequest
   Uses a test certificate.
9. http://timestamp.digicert.com
   Documentation (along with the certificate used, that changes every so often) is there : https://knowledge.digicert.com/general-information/rfc3161-compliant-time-stamp-authority-server

Timestamping services that went offline :

1. http://dse200.ncipher.com/TSS/HttpTspServer
2. http://tsa.safecreative.org
3. https://timestamp.geotrust.com/tsa
4. http://timestamp.globalsign.com/scripts/timstamp.dll
5. http://services.globaltrustfinder.com/adss/tsa

You can also try one of these publicly accessible RFC 3161 compliant client applications:

1. TimeStampClient

thanks jariq. #2 did the job, time stamp is embedded but could not be verified, but that was expected. thanks again !!! – Puss

I added one from symantec, not sure how that verification on timestamp works, but this one is verified, maybe because I own a symantec code signing certificate? This answer goes in-dept: #19528956 – Elisaelisabet

if you really do mean "Feel free to edit the answer and extend the list." then you should convert this answer into a community wiki. otherwise it's time consuming for us reviewers to to vet the suggested edit. – Frenchy

@JeffPuckettII Thanks for the suggestion - I have converted answer to community wiki. I didn't know such option existed :) – Bifacial

Adding to this list, as the question is already closed: truetimestamp.org – Valenba

@Valenba but truetimestamp.org seems not to be RFC 3161 compliant cryptographic service. It seems to be only online database of the hash values. – Bifacial

The timestamp provider tsa.safecreative.org uses certificates to sign the timestamps which uses a test CA as issuer. And that is not good at all. – Calypso

I think we need to review the RFC, as I am really not confident with some of these alternate timestamp servers. After switching to a different one last build, I had, for the first time ever, an unsigned file get out. Now, that was probably my scripting, but I'm still looking into it. Does anyone know of a question already asks that clarifies this matter? I mean, are any good? And, if so, why not just create my own? So, I suspect there are limitations (OS support maybe), but I don't know. – Kokand

Note that zeitstempel.dfn.de does not permit commercial use. – Clemmieclemmons

Hi Guys, I am planning to use timestamp.globalsign.com/scripts/timstamp.dll for digital sign pdf on enterprise financial services. Is there any risk of data leakage? – Geyserite

A secret one used by google play.googleapis.com/play/log/timestamp – Wearable

Symantec timestamping services are being shut down on October 31st, 2019 (so don't re-add their URLs!) – Sadducee

Another one to add that worked for me: timestamp.comodoca.com/authenticod – Stylobate

from Europa DSS you have a list of free TSP for testing purpose dss.nowina.lu/pki-factory/tsa/list For example this one dss.nowina.lu/pki-factory/tsa/good-tsa – Vip
