#2718 Issue closed: Insecure default NETFS encryption method BACKUP_PROG_[DE]CRYPT_OPTIONS="... des3 ..."¶
Labels: enhancement, no-issue-activity
therealjeybe opened issue at 2021-11-20 13:08:¶
-
ReaR version ("/usr/sbin/rear -V"): 2.6 / 2020-06-17
-
OS version ("cat /etc/os-release"): Fedora Linux, Version 35
-
ReaR configuration files ("cat /etc/rear/site.conf" and/or "cat /etc/rear/local.conf"): Default shipped with OS
-
Description of the issue:
ReaR uses Triple-DES as default for encryption/decryption of NETFS tar backups [1]. Triple-DES is deprecated and shouldn't be used without a specific reason to do so, and even if it's used it should only be used in carefully applied settings and scenarios. AES should be seen as more secure successor and used instead of Triple-DES wherever possible. This is described by the German federal agency of security in information technology (in german), by the NIST [1] [2] and also by OpenSSL.
This is a problem as I don't see a reason to use a weak data encryption in this case. Many other backup solutions / methods (even those integrated with ReaR) prove, that it's possible to use a modern, up-to-date encryption method (Borg Backup, restic [1] [2]). -
Workaround, if any: Use a custom encryption/decryption command or do not use NETFS as backup method.
-
Solution: Use a appropriate encryption method by default.

In ReaR we try to keep things backward compatible
as far as possible with reasonable effort.
Our release notes show currently at
https://github.com/rear/rear/blob/master/doc/rear-release-notes.txt#L2513
ReaR-2.6 is supported on the following Linux based operating systems:
o Fedora 29, 30, 31, and 32
o RHEL 6, 7, and 8
o CentOS 6, 7, and 8
o Scientific Linux 6 and 7
o SLES 12 and 15
o openSUSE Leap 15.x
o Debian 8, and 9
o Ubuntu 16, 17, and 18
...
ReaR-2.6 may still work for SLES 11 and openSUSE Leap 42.x or even
earlier openSUSE versions but it is no longer sufficiently well tested there
so arbitrary regressions could appear.
Here what openssl ciphers are documented as supported
for those Linux distributions that I have available as virtual machines:
