The Portable OpenSSH is a release of OpenSSH specifically designed for Mac OS X operating systems, providing users with enhanced security and portability. This software enables users to securely connect to remote machines and transfer files, with the added benefit of being able to use it on the go.
While adding portability code to OpenSSH is necessary to enable it to run on other Unix operating systems, it can be difficult due to differences between them, especially considering that OpenSSH does authentication. Nonetheless, Portable OpenSSH is designed to run on various Unix operating systems including Mac OS X, AIX, HP-UX, Irix, Linux, NeXT, SCO, SNI/Reliant Unix, Solaris, Digital Unix/Tru64/OSF, Cygwin, and more.
Portable OpenSSH is created by following the development process of the official version, but the releases are not synchronized. Portable releases are distinguished from other releases by the 'p' suffix in their version number, such as 4.4p1. The official OpenBSD source will not include the 'p' suffix but will instead increment the version number when stable spots are hit in the package development.
It's essential to note that Portable OpenSSH is released under the BSD License. If you need OpenSSH to run on a Unix operating system other than OpenBSD, the Portable OpenSSH is an excellent option to consider.
