Last year there was a discussion where it was mentioned that iwd uses "ecb(arc4)" via AF_ALG. So can we really remove it yet? See https://lkml.kernel.org/r/97bb95f6-4a4c-4984-9eab-6069e19b4...@holtmann.org Note that the code isn't in "iwd" itself but rather in "libell" which iwd depends on: https://git.kernel.org/pub/scm/libs/ell/ell.git/ Apparently it also uses md4 and ecb(des) too. Marcel and Denis, what's your deprecation plan for these obsolete and insecure algorithms? - Eric
