Ive installed john ripper with snap, and now, im using with force brute for unecrypting zip files..
Im using the following set of characters for encrypting, 'a-z0-9' and a six character word like this:
VRAN="$(cat /dev/urandom | tr -dc 'a-z0-9' | fold -w 6 | head -n 1)"
For john and the prevous key im using the set of characters: --incremental:LowerNum
sudo snap run john-the-ripper --incremental:LowerNum johnpass.hash
The problem Ive got, its that sometimes It only takes three minits to decode the 6 characters password, and sometimes seems never ends.. I fell something is not working properly.
Output
system_key.go:127: cannot determine nfs usage in generateSystemKey: cannot parse /etc/fstab: expected between 3 and 6 fields, found 7
Using default input encoding: UTF-8
Loaded 1 password hash (PKZIP [32/64])
