Use of encryption
Prior to version 1.9.0, Sudo did not include support for encrypting
data and was not subject to any export controls. However, starting
with version 1.9.0, Sudo supports encrypted connections between the
daemon and the sudoers plugin.
Specifically, TLS 1.2 or higher is used which supports strong
encryption. The actual encryption algorithms used depend on
the Sudo configuration as well as
the version of OpenSSL
sudo is linked with (sudo does not include an implementation of any
encryption algorithms itself).
Some users may need to know whether Sudo is covered under
U.S. export restrictions, specifically the
Export Administration Regulations (EAR)
and if so, what its Export Control Classification Number (ECCN) might be.
ECCN for Sudo
By the terms of
Section 734.7(a)(4) of the EAR
Sudo is considered to be published software.
To the best of my knowledge, this means that Sudo falls under ECCN
5D002.c.1 and, as published software, qualifies for
License Exemption TSU (Technology and Software - Unrestricted)
As such, there are no U.S. export restrictions that prohibit you
from downloading Sudo.

It also applies to other open source software, including Sudo.

export controls affect Open Source software.
