PSSH is an open-source SSH server designed to be simple, small, and secure. It focuses on providing core SSH functionality without unnecessary bells and whistles.
PSSH (Portable SSH) is an open-source SSH server program designed to prioritize simplicity, small size, and security. It is developed and maintained by the OpenBSD team to provide a minimal and dependency-free SSH server option.
Unlike more complex SSH servers like OpenSSH, PSSH aims to offer only essential SSH protocol features and functionality in a compact package. This makes PSSH well-suited for embedding into appliances, small systems, and applications where a full OpenSSH install would be overkill.
Some key features of PSSH include:
PSSH prioritizes being a simple, auditable codebase focused narrowly on core SSH functionality over supporting every possible SSH extension and edge case. This can make it a good fit for developers and systems administrators interested in SSH without unnecessary complexity.
