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 The old certificate (no longer valid as of March 2026) can be downloaded here: Freetsa 2016-2026 Old TSA Certificate: tsa.crt_expired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.

B [updated] - Ys-sxt-v4.2

The YS-SXT-V4.2 B is a powerful and versatile device that has the potential to revolutionize industrial control systems. With its advanced features, robust design, and user-friendly interface, it is an ideal solution for organizations seeking to optimize their operations and improve efficiency. As technology continues to evolve, the YS-SXT-V4.2 B is poised to play a significant role in shaping the future of industrial automation and telecommunications.

The YS-SXT-v4.2 B is built specifically to survive high vibration environments while supplying heavy continuous current to electric drivetrees. Component / Metric Specifications & Parameters MindMotion MM32SPIN06 series (ARM Cortex-M0 core) System Voltage Compatibility Native 36V DC up to 42V peak charging capacity Supported Motor Type

While the exact meaning of ys-sxt-v4.2 b is not publicly documented, a logical breakdown based on industrial naming conventions can be proposed:

Before replacing, ensure your original board is marked YS-SXT-4.2 B .

If you are looking to replace or repair a unit with this board, it is typically part of a standard 36V–42V controller set. Compatible Vehicles

Open-source projects, such as the Hoverboard Firmware Hack Gen2 (MM32 variant on GitHub), have integrated external ESP32 microcontrollers. These boards use an autodetect program to communicate directly with the motor drivers, bypassing the locked native MCU altogether. Troubleshooting and Repairing Common Faults

It is highly recommended to buy the motherboards as a matched pair. Retailers on marketplaces like AliExpress and Amazon DE bundle the YS-SXT-V4.2 A and B boards together with a matching Bluetooth transceiver module, power button, and status indicator LEDs for roughly $35 to $50.

When purchasing a replacement for the YS-SXT-V4.2 B, it is vital to ensure compatibility. While some boards look similar, their firmware or pinouts might differ between manufacturers, such as the Soflow Flowpad X. Using an incompatible board can lead to permanent damage to your hoverboard.

Ensure all pin connectors (3-pin and 4-pin) are securely plugged into the B board and the A board.
