The menu offers five public RFC 3161 authorities: DigiCert, Sectigo,

|
SSL.com, FreeTSA, and MeSign. There is no field for a custom URL, so
|
|
the choice is limited to those presets.

|
<i data-lucide="plus" class="faq-d-icon"></i>
|

</summary>
|
|
<p class="faq-d-a">
|
|
No. The tool has to contact the chosen TSA over the internet to
|
|
obtain the signed timestamp token; everything else, including
|
|
hashing the file and embedding the token, happens in your browser.
|
|
If the request fails you can pick another server and try again.

<i data-lucide="plus" class="faq-d-icon"></i>

<p class="faq-d-a">
|
|
A digital signature proves who signed the document and needs your
|
|
own certificate, while a document timestamp proves only when the
|
|
document existed, vouched for by the TSA. If you need both, sign
|
|
first with
|
|
<a

|

|
|
class="text-indigo-300 hover:text-indigo-400"

</summary>
|
|
<p class="faq-d-a">
|
|
The timestamp is appended as an incremental update rather than a
|
|
rewrite of the file, so an existing signature stays intact and
|
|
verifiable, and the timestamp shows as its own entry in the reader's
|
|
signature panel.

<i data-lucide="plus" class="faq-d-icon"></i>

</summary>
|

<p class="faq-d-a">
|
|
No. The timestamp is invisible; it lives in the file's signature
|
|
data and shows up in the signature panel of Acrobat and similar
|
|
readers, not as a stamp on the page. The downloaded file keeps its
|
|
original name.

<p class="faq-d-a">
|
|
Most often the TSA didn't respond or your connection dropped, so try
|
|
another server from the list. On self-hosted copies of BentoPDF
|
|
served over HTTPS, the servers that only offer HTTP endpoints need a
|
|
CORS proxy configured at build time; FreeTSA uses HTTPS and works
|
|
without one.

</summary>
|
|
<p class="faq-d-a">
|
|
Readers validate the token against the TSA's certificate chain, so
|
|
it verifies as long as that chain is trusted. This tool doesn't
|
|
embed long-term validation (LTV) data, so verification years later
|
|
depends on the reader still being able to check the TSA's

|
certificates.

<p class="faq-d-a">
|
|
Open the signature panel in Adobe Acrobat Reader or another
|
|
signature-aware viewer; the timestamp is listed there with its time
|
|
and the authority that issued it. If the reader trusts the TSA's
|
|
certificate chain, it reports the timestamp as valid.
