I wonder - conceptually compression does not differ much from stream
ciphers - you put some data in and you get some data out.

The only real difference is that the compression does not need to have
any private key [but it can have 'public' as the level of compression

Except naming they do not differ much (on the other hand - they do share
subsystem in Linux kernel).
