tl;dr: Germany has a censorship federal agency called BPjM which maintains a
secret list of about 3000 URLs. To keep the list secret it is distributed in
the form of md5 or sha1 hashes as the "BPJM-Modul". They think this is safe.
This leak explains in detail that it is in fact very easy to extract the
hashed censorship list from home routers or child protection software and
calculate the cleartext entries. It provides a first analysis of the
sometimes absurd entries on such a governmental Internet censorship list.
