    FreeRDP

    FreeRDP

    FreeRDP is a free remote desktop protocol library and clients

    FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Enjoy the freedom of using your software wherever you want, the way you want it, in a world where interoperability can finally liberate your computing experience. The nightly builds are installed into /opt/freerdp-nightly and can be installed in parallel with the distributions regular freerdp package. Network tracing of RDP can be quite a challenge due to a number of factors such as encryption, compression, and the fact that these protocol features cannot always be disabled or worked around. One of the easiest way of decrypting RDP traffic is to configure the server with a self-signed certificate for which the private key is known, and then use this certificate with a network tracing tool to automatically decrypt the packets.

    libusb

    libusb

    A cross-platform library to access USB devices

    libusb is a library for USB device access from Linux, macOS, Windows, OpenBSD/NetBSD, Haiku and Solaris userspace. It is written in C (Haiku backend in C++) and licensed under the GNU Lesser General Public License version 2.1 or, at your option, any later version. libusb is a C library that provides generic access to USB devices. It is intended to be used by developers to facilitate the production of applications that communicate with USB hardware. Using a single cross-platform API, it provides access to USB devices on Linux, macOS, Windows, etc. No special privilege or elevation is required for the application to communicate with a device. All versions of the USB protocol, from 1.0 to 3.1 (latest), are supported. libusb is abstracted internally in such a way that it can hopefully be ported to other operating systems.

    AWS IoT Device Defender Library

    AWS IoT Device Defender Library

    Client library for using AWS IoT Defender service on embedded devices

    The Device Defender library enables you to send device metrics to the AWS IoT Device Defender Service. This library also supports custom metrics, a feature that helps you monitor operational health metrics that are unique to your fleet or use case. For example, you can define a new metric to monitor the memory usage or CPU usage on your devices. This library has no dependencies on any additional libraries other than the standard C library, and therefore, can be used with any MQTT client library. This library is distributed under the MIT Open Source License. This library has gone through code quality checks including verification that no function has a GNU Complexity score over 8, and checks against deviations from mandatory rules in the MISRA coding standard. Deviations from the MISRA C:2012 guidelines are documented under MISRA Deviations. This library has also undergone static code analysis using Coverity static analysis.

    AWS IoT Device Shadow library

    AWS IoT Device Shadow library

    Client library for using AWS IoT Shadow service on embedded devices

    The AWS IoT Device Shadow library enables you to store and retrieve the current state (the “shadow”) of every registered device. The device’s shadow is a persistent, virtual representation of your device that you can interact with from AWS IoT Core even if the device is offline. The device state is captured as its “shadow” within a JSON document. The device can send commands over MQTT to get, update and delete its latest state as well as receive notifications over MQTT about changes in its state. Each device’s shadow is uniquely identified by the name of the corresponding “thing”, a representation of a specific device or logical entity on the AWS Cloud. See Managing Devices with AWS IoT for more information on IoT "thing". More details about AWS IoT Device Shadow can be found in AWS IoT documentation. This library is distributed under the MIT Open Source License.

    TFT_eSPI

    TFT_eSPI

    Arduino and PlatformIO IDE compatible TFT library

    An Arduino IDE compatible graphics and fonts library for 32-bit processors. The library is targeted at 32-bit processors, it has been performance-optimized for STM32, ESP8266 and ESP32 types. The library can be loaded using the Arduino IDE's Library Manager. Direct Memory Access (DMA) can be used with the ESP32, RP2040, and STM32 processors to improve rendering performance. "Four wire" SPI and 8 bit parallel interfaces are supported. Due to the lack of GPIO pins, the 8-bit parallel interface is NOT supported on the ESP8266. 8 bit parallel interface TFTs (e.g. UNO format mcufriend shields) can use with the STM32 Nucleo 64/144 range or the UNO format ESP32. ILI9341 and ST7796 SPI-based displays are recommended as starting points for experimenting with this library. The library supports some TFT displays designed for the Raspberry Pi (RPi) that are based on a ILI9486 or ST7796 driver chip with a 480 x 320-pixel screen.

    casefix

    a small set of casing tools for use by all

    The primary part of the casefix project is a small c library of case editing functions, the heart of which is 7 streaming case editors. Also, there are 3 functions that interface char arrays and strings to the streaming editors. So the library can modify the casing of any character, character block (word), any character string, character array, or any character stream. Currently, libcasefix only handles 7 or 8 bit character sets with some support for UTF-8. With that in mind casefix does support a number of character sets for internationalization. Also, there is a casefix command that implements the functionality of the casefix library for use at the command line.

    LibNetBlock - A Network Blocking Library

    LibNetBlock - A Network Blocking Library

    A library for blocking access to network on-the-fly

    LibNetBlock is a library that on-the-fly (by preloading) prevents a program under its control to use the network, to help to keep the user's privacy, prevent data leakage and virus spreading. You can think of LibNetBlock as a simple layer-7 (L7) firewall that simply blocks the network access for the program it controls. There is NO NEED to rebuild your software, because LibNetBlock is a pre-loadable library, meaning you just need to RUN the software with LibNetBlock loaded. LibNetBlock is also a development library. See the project homepage https://libnetblock.sourceforge.io and the project Wiki in the menu above.

    LibSecRm - Secure Removal Library

    LibSecRm - Secure Removal Library

    A library for secure deleting data on-the-fly

    LibSecRm (LIBrary for SECure ReMoval) is a set of replacements for these standard C functions which cause data removing from files. The data is first securely wiped on-the-fly, to protect the user's privacy, then the original functions are called. There is NO NEED to rebuild your software, because LibSecRm is a pre-loadable library, meaning you just need to RUN the software with LibSecRm loaded. LibSecRm is also a development library. The following wiping methods are supported: Gutmann-like, random, Schneier, DoD. See the project homepage https://libsecrm.sourceforge.io and the project Wiki in the menu above. To wipe data that was left on the drive by using "normal" delete operations, you can take a look at WipeFreeSpace (https://wipefreespace.sourceforge.io), which wipes the space used by files marked as deleted (and other things, too).
