zeitstempel.dfn.de is working fine on Linux when signing a LibreOfficeWriter to PDF export. I might try this on "my" Windows machine in LibreOffice in the office after lockdown as well. (A Windows machine is never mine, plus this is a machine my company owns.)
Here is the list I used on Windows to sign PowerShell Scripts
I cannot use http://timestamp.digicert.com now. Anyone ran into the some problem?
@zhanzhenzhen I test no problem, but in China digicert easy to connect timeout, slow access and even packet loss, so it is not recommended to use, I suggest you use it http://time.certum.pl
@sln162 I tested again and yes it seems there's no problem with OpenSSL, but when I tried to timestamp a PDF document using the DigiCert TSA in Adobe Acrobat Reader DC, it said the protocol is not supported. In the past I can timestamp PDF documents using DigiCert TSA but now I can't. I don't know why.
@sln162 Sorry for the stupid mistake. I didn't find that there's an error on DigiCert's page:
https://knowledge.digicert.com/generalinformation/INFO4231.html
On that page there's only one slash http:/. I just copy and paste that. OpenSSL is error-tolerant, but Adobe Acrobat isn't error-tolerant.
Now DigiCert works fine.
On macOS, I specified http://timestamp.entrust.net/TSS/RFC3161sha2TS for codesigning, and this caused error CSSMERR_TP_NOT_TRUSTED when verifying the signature. I switched to http://timestamp.apple.com/ts1 and it worked.
Anybody knows why or other solutions?
Is anyone else getting a "server not found" in Adobe Reader for http://timestamp.globalsign.com/scripts/timestamp.dll?
Edit: Just saw that globalsign hosts another rfc3161 server at http://rfc3161timestamp.globalsign.com/advanced, which works perfectly in Adobe Reader. I'll go with that one from now on. :)
Does anyone know the state of the http://rfc3161timestamp.globalsign.com time servers? I was originally using standard, and that stopped working, went to advanced which was working for a week, and just now, it's redirecting me to a page that makes it look like it's now a paid service? Is it a temporary outage or did they just make it a paid product?
Hi @seraphire, just noticed the same. I'm not sure what's going on but I'm migrating to a different timestamp server.
First, SHA1 of globalsign has stopped supporting. Reference News: https://globalsign.cn/news/newsdetail_93.shtml
http://timestamp.globalsign.com/scripts/timstamp.dll is SHA1,so it's not available.
http://rfc3161timestamp.globalsign.com/advanced It can't be used half an hour ago. Just now, it's no problem. It may not be stable. You can use other ones first
@seraphire It's a temporary outage...
Thanks @cassolmc. Here's the GlobalSign status URL for anyone looking for it. https://status.globalsign.com/
This is maybe a little off topic - but I built such a server for self hosting. It can be found at https://github.com/elbosso/rfc3161timestampingserver
What is the difference between http://timestamp.globalsign.com/?signature=sha2 and http://rfc3161timestamp.globalsign.com/advanced ?
The first one is not RFC3161 compliant ? Does it change anything ?
Hey Guys, i'm new in java and i want someone to help me. i need to know how to implement a Timestamp method/function using these TSA...
i want to know how to timestamp files.
Thank you.

Well - you can try and have a look at https://github.com/elbosso/rfc3161client
Hi guys, I just found a new free TSA. http://tsa.mesign.com
I found it from their website: https://www.mesign.com/en-us/tsa/index.html
Hope this helps.
@go2ready It cannot be used for program signing.
I did a complete review of every site on this list by trying to connect to them using elinks, a text-mode browser. Here are my results:
https://freetsa.org
-- YES! THIS ONE ACTUALLY WORKS!
-- It gives detailed instructions on how to use it with the OpenSSL toolset
-- Has a form where you can give data to the browsers, which will send a hash to their server
http://timestamp.globalsign.com/scripts/timstamp.dll
http://timestamp.globalsign.com/?signature=sha2
http://rfc3161timestamp.globalsign.com/advanced
-- These sites all bring up the same page. It appears they no longer offer a free service.
https://timestamp.geotrust.com/tsa
-- Timed out
http://timestamp.sectigo.com
-- No longer a free service; must sign up for a trial. Their only link to a client application is from Microsoft.
http://timestamp.wosign.com
http://tsa.startssl.com/rfc3161
-- These two timed out with no output.
http://time.certum.pl
-- Retured the following output:
Time Stamp Service Version 2.0

http://timestamp.digicert.com
-- No ouput. Digicert no longer appears to offer anything for free, not even email sigining.
http://dse200.ncipher.com/TSS/HttpTspServer

-- Page indicates the service is shutting down in July 2021

David, it appears you're actively maintaining the list. I'd like to suggest you add text to the gist indicating when was the last time you updated it.
@Neepawa
Pretty sure that this is not the way to test if they work or not. I'm still not entirely sure how to easily fully verify if the services are working, but if you look at freetsa.org in the "Basics: TCP-based client" it shows how the services can be talked to via openssl and curl.
Then you can see in the resulting tsr file whether it worked and so for example http://timestamp.digicert.com seems to output valid data. And so does http://rfc3161timestamp.globalsign.com/advanced
Note that there is a new GlobalSign URL:
http://timestamp.globalsign.com/tsa/r6advanced1
I just used it and it works for me. The other GlobalSign URLs seem to be dead indeed.
Don't use https://ca.signfiles.com/tsa/get.aspx
It is a demo server with open configuration.

Hello everyone, could i know how you verified that ? do you use any Java program to verify those links ???
Thank you
In EU trust list, up to SHA512
Limitation applies to non-registered users: no more than 100 requests within one month; the beginning and the end of the month are defined in UTC time.
It helped me a lot. Thank you :)
So for anyone wondering, here's a short list of which companies are "approved" by Adobe for signing: https://helpx.adobe.com/sign/using/custom-time-stamp-providers.html#ApprovedTimeStampProviders
There's also a longer list here: https://helpx.adobe.com/ca/acrobat/kb/approved-trust-list1.html
@arulrajnet That page is down at the moment, but I've replaced
http://timestamp.comodoca.com/rfc3161withhttp://timestamp.sectigo.comunless I hear otherwise. =)@ragnarekker The signatures themselves can be validated, so HTTPS isn't technically required.
