DES keys

I ran into an issue where several auth/wrkey calls and adding a user on 9front auth via auth/changeuser ended with DES being used.

As per the FQA section you can convert DES keys to AES:

; auth/keyfs
; auth/convkeys -ap /adm/keys
# You'll be prompted for the hostowner password
; auth/wrkey
# Enter the hostowner password


; auth/keyfs
; auth/changeuser glenda
# Enter hostowner password
; auth/enable glenda
