OpenSSH 9.9 released September 20, 2024

OpenSSH is the premier connectivity tool for remote login with the SSH protocol. It encrypts all traffic to eliminate eavesdropping, connection hijacking, and other attacks. In addition, OpenSSH provides a large suite of secure tunneling capabilities, several authentication methods, and sophisticated configuration options.

The OpenSSH suite consists of the following tools:

• Remote operations are done using ssh, scp, and sftp.
• Key management with ssh-add, ssh-keysign, ssh-keyscan, and ssh-keygen.
• The service side consists of sshd, sftp-server, and ssh-agent.

OpenSSH is developed by a few developers of the OpenBSD Project and made available under a BSD-style license.

OpenSSH is incorporated into many commercial products, but very few of those companies assist OpenSSH with funding.

Contributions towards OpenSSH can be sent to the OpenBSD Foundation.
