Secure, Trusted Timestamps for Long-term Signatures. GlobalSign's trusted timestamping Software as a Service (SaaS) provides a low cost and easy method to apply RFC 3161 trusted timestamps to time-sensitive transactions through independently verified and auditable date and UTC (Coordinated Universal Time) sources. Adobe Acrobat Timestamp Servers Easily add SecureTime® proof to your PDF document. Adobe® Acrobat products have built-in support for adding a secure timestamp to your PDF document. We will show you how to do the configuration below.
Hi all,
According to the RFC 3161 standard, a trusted timestamp is a timestamp issued by a Trusted Third Party (TTP) acting as a Time Stamping Authority (TSA). It is used to prove the existence of certain data before a certain point (e.g. Contracts, research data, medical records.) without the possibility that the owner can backdate the timestamps. To configure a timestamp server, you need the server name and the URL, which you can obtain from an administrator or a security settings file. If you have a security settings file, install it and don’t use the following instructions for configuring a server. Ensure that you obtained the security settings file from a trusted source.
The other day a customer of mine was trying to add an Authenticode signature with timestamp to their PowerShell scripts with PowerShell itself and its Set-AuthenticodeSignature cmdlet. He was able to sign the scripts just fine, but when using the timestamp option the cmdlet was nothonoring InternetExplorer Proxy settings and the timestamping process failed.
If you have never seen how to add such a signature with PowerShell, check the following sample:
First we can create a test certificate in i.e. a cmd.exe:
Then we can create a signature with timestamp in PowerShell:

So my customer tried to use signtool.exe instead, with the same results: IE proxy settings are not getting used at all and they get an error like the following:

Note that if we open Internet Explorer and enter http://timestamp.globalsign.com/scripts/timstamp.dll into the address bar, IE presents the credentials dialog box to send to the proxy and we can access the timestamp server without problems.
The cause of this issue is the following:
All signing methods we saw in my previous posts (SignTool, CAPICOM, etc.) end up using SignerSignEx API to sign, and SignerTimeStampEx API to timestamp the signature. The same applies to PowerShell's Set-AuthenticodeSignature cmdlet.

SignerTimeStampEx will connect to the remote timestamp server in a very simple way, without using any proxy info or user credentials. And this is not configurable in any way.
So I'm afraid all signing methods we have at our disposal suffer from this limitation in the API.
In order to timestamp code, it is necessary to have unrestricted access to the Internet.

I hope this helps.
