[edit] Technology

Dropbear implements version 2 of the Secure Shell (SSH) protocol.

The cryptographic algorithms are implemented using third party cryptographic libraries included internally in the Dropbear distribution. It derives some parts from OpenSSH to handle BSD-style pseudo terminals.^[1]

[edit] Features

Dropbear implements the complete SSH version 2 protocol in both the client and the server. It does not support SSH version 1 backwards-compatibility to save space and resources, and to avoid the inherent security vulnerabilities in SSH version 1.
