SSHDd

SSHDd is a lightweight and secure shell daemon designed for embedded systems and other resource-constrained environments. It is a fork of the OpenSSH project, which is widely used for secure remote access to Unix-like operating systems. SSHDd aims to provide a minimalistic implementation of the SSH protocol, focusing on security and efficiency.

The daemon supports key-based authentication, which is a more secure method compared to password-based authentication. It also includes support for public key authentication using algorithms such as RSA, DSA, and ECDSA. Additionally, SSHDd supports various encryption algorithms, including AES, 3DES, and Blowfish, to ensure secure communication between the client and server.

One of the key features of SSHDd is its small footprint, making it suitable for embedded systems with limited resources. The daemon is designed to be lightweight and efficient, consuming minimal memory and CPU resources. This makes it an ideal choice for IoT devices, routers, and other embedded systems where resource constraints are a significant concern.

SSHDd also includes support for SFTP (SSH File Transfer Protocol), allowing users to securely transfer files between the client and server. The daemon is highly configurable, enabling system administrators to tailor its behavior to specific requirements. It supports various configuration options, including port forwarding, X11 forwarding, and TCP keepalives.

Overall, SSHDd is a robust and secure shell daemon that provides essential SSH functionality in a resource-efficient manner. Its focus on security, efficiency, and configurability makes it a valuable tool for embedded systems and other resource-constrained environments.
