at_c is the client implementation of the atProtocol. Similar to libraries needed for HTTP communication, the C SDK is required for embedded devices and C applications to interact with their atServer through the atProtocol. This SDK facilitates edge encryption, server authentication, and simplifies protocol interactions for users. Among the SDKs I contributed to, including at_java, at_pico_w, and at_esp32, at_c emerged as the most complete due to customer demand. By August 2024, we achieved the v0.1.0 beta release.

Cryptography Features:

• RSA 2048 encrypt/decrypt
• RSA 2048 sign/verify
• AES 256 CTR encrypt/decrypt
• AES key generation
• RSA 2048 key importing
• SHA 256 hashing

atProtocol Features:

• CRUD operations: Put, Get, Delete
• Events: Notify, Monitor
• AtKey: metadata, to/from string
• Authentication: PKAM authentication

noports is a company-wide project designed to allow users to remotely access their machines without requiring open ports. It provides a secure and user-friendly solution, especially for non-tech-savvy users. The project is currently under development and not yet publicly available.

My Contribution:

• Developed the at_c C SDK, a core dependency for noports' C SSHNPD.
• Created the initial set of end-to-end tests using Docker to simulate the noports handshake process. This involved closing ports on Docker machines and simulating one container SSH'ing into another.
