As the name implies, Openwall GNU/*/Linux draws source code and design concepts from numerous sources, most importantly to the project is its usage of the Linux kernel and parts of the GNU userland, others include the BSDs, such as OpenBSD for its OpenSSH suite and the inspiration behind its own Blowfish-based crypt for password hashing, compatible with the OpenBSD implementation.

Public domain software

The Openwall project maintains also a list of algorithms and source code which is public domain software.[1]

LWN.net reviewed Openwall Linux 3.0.[2] They wrote:

The first question most people will have is: what is so "security-enhanced" about Owl? Aren't major Linux distributions such as Red Hat Enterprise Linux, Ubuntu, openSUSE, and so on secure? Of course, they continuously patch known security vulnerabilities and some of them (Red Hat in particular) implement security features to decrease the impact of vulnerabilities, but none of them really are focused on preventing vulnerable software from getting into the distribution in the first place.
