freeTSA.org provides a free Time Stamp Authority. Adding a trusted timestamp to code or to an electronic signature provides a digital seal of data integrity and a trusted date and time of when the transaction took place.

Important: The tsa.crt certificate has been updated and modernized. The validity of timestamps from March 16, 2026, is until February 2040. The time stamps now use Elliptic-curve cryptography P-384 (secp384r1). The old certificate (no longer valid as of March 2026) can be downloaded here: Freetsa 2016-2026 Old TSA Certificate: tsa.crt_expired

Trusted timestamping is the process of securely keeping track of the creation and modification times of a document. Security here means that no one - not even the owner of the document - should be able to change it once it has been recorded provided that the timestamper's integrity is never compromised. FreeTSA trusted timestamping Software as a Service (SaaS) provides an easy method to apply RFC 3161 trusted timestamps to time-sensitive transactions through independently verified and auditable date and UTC (Coordinated Universal Time) sources.

Adding a trusted timestamp to code or to an electronic signature provides a digital seal of data integrity and a trusted date and time of when the transaction took place. Recipients of documents and code with a trusted timestamp can verify when the document or code was digitally or electronically signed, as well as verify that the document or code was not altered after the date the timestamp vouches for. (Readme).

For multiple files, the general concept is that timestamping a single file that contains an aggregate list of fingerprints of other files, also proves that these other files must have existed before the aggregate file was created, provided that both the aggregate file and the referenced file are available during verification process. Freetsa also offers the possibility of URLs timestamps (do not abuse). If you are interested in implementing timestamps on your project / company using the FreeTSA service, you can contact me for specific requirements. Freetsa can also be used within the Tor anonymity network.

Making timestamps from Android/iOS devices is possible and no software installation is required (Video). To timestamp a picture you must go to the "Online Signature" section in the browser, click "Choose a file" and select "Use camera". Once the photo or video are completed, you can download the timestamp (TimeStampResponse). Just that. You also may select any other file available in the device if you choose so.

Freetsa.org offers free OCSP and CRL, NTP, DNSCRYPT, DNS (Port 53) and DNS over TLS (DoT) services for time synchronisation and encrypted name resolution respectively. The resolution of DNSCRYPT (Port 553) do not have any type of restriction (SPAM, Malware, Parental,...). No logs are saved. Like the rest of the services offered by FreeTSA, DoT accepts TCP connections to port 853 on all its IPv4/IPv6 addresses.

Before diving into complex system changes, ensure the installer itself isn't the problem. Use an MD5 checker or a similar tool to verify the hash of your downloaded file against the one provided by the source. If verification fails or you lack a hash, delete the file and re-download it directly from the official publisher's website.

First, a hard truth: The original developer (Insane Stuff/ASX) stopped maintaining it years ago.

A: ISArcExtract is used to extract files from the installation media during the installation or upgrade process.

The error is a highly frustrating issue that typically interrupts the installation of large, heavily compressed applications or repackaged games on Windows 11 . This error is tied closely to the decompression modules handled by ISDone.dll and unarc.dll . It occurs when an installer fails to locate or unpack the compressed temporary files (often .bin archives) required to complete the installation.

This error usually triggers during the decompression phase of an installation because the system cannot properly extract the files. Frequent culprits include: Insufficient RAM or Virtual Memory : The extraction process runs out of space to swap data. Antivirus Interference : Windows Defender or third-party software blocks IsDone.dll thinking they are suspicious. Corrupted Archive : The installer files themselves are damaged or incomplete. System Permissions

Here are some key points about ISArcExtract and Windows 11 updates:

The ISArcExtract function is closely tied to ISDone.dll and unarc.dll . These background dynamic link libraries manage the uncompressing and processing of large archive structures—most commonly found in high-compression gaming "repacks" (such as FitGirl or DODI) or split-volume enterprise software deployment suites.

If parts of the source archive are missing or broken, the engine cannot complete the decompression cycle.

Ensure there are no spaces or special symbols in any file or folder name.
