How to disable Speck from Linux Kernel

Linux Kernel 4.17 saw the inclusion of NSA’s ‘controversial’ encryption algorithm Speck. Linux Kernel 4.18 will see Speck being available as a supported algorithm with fscrypt and not everyone is happy about it.

Before you panic or form wrong conclusions, you should know that Speck is not a backdoor. It’s just a not-so-strong encryption algorithm from American agency NSA and it’s available as a module in Linux Kernel.


...check the Linux kernel version and if it uses Kernel 4.17, you may blacklist the Speck kernel module.

If it doesn’t exist already, create /etc/modprobe.d/blacklist.conf file and add the following lines to it:

blacklist CONFIG_CRYPTO_SPECK
