So can we really remove it yet? See https://lkml.kernel.org/r/97BB95F6-4A4C-4984-9EAB-6069E19B4A4F@xxxxxxxxxxxx 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
