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 188.8.131.52 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
