@Manouchehri ,, Thanks for compiling this list. My interest is in free general-purpose timestamping service (e.g. stamping pdf, zip files) and this page was near the top of Google's search results, so a good starting point for a comprehensive list of freeTSA servers, but some of the links appear to be dead dse200.ncipher.com/TSS/HttpTspServer : address could not be found for either the full URL or the base address dse200.ncipher.com. timestamp.geotrust.com/tsa : has been retired by Symantec and replaced with sha256timestamp.ws.symantec.com/sha256/timestamp (see INFORMATIONAL | Discontinued Use of (Legacy) SHA1 RFC 3161 timestamp service - DigiCert) and appears to be a direct link to their RFC3161 timestamper and not a "landing" page. Not 100% certain but it looks like the "timestamp.dll" links are direct RFC3161 timestamp server links designed to be used for code-signing only (possibly by Microsoft's SignTool). For what I came to this page for the best current (1/19/2019) link for genuinely free general-purpose timestamping is freetsa.org. No time to go through all the links, but this of interest so I will update this comment as time allows. Thanks again for the scholarship compiling this resource. |

Excellent resource! Is anyone generating, signing and timestamping PDFs on the fly? Currently working with TCPDF which signs ok but does not have time stamping implemented. |

I'm finding a free TSA that optimized for Asia users.
Do you know any?
(All above servers take at least 200ms for a ping response)
PS: The first server I've found is: http://tsa.wotrus.com (~75ms)
