Transparent compression and encryption

in windows you can encrypt and compress file via it properties.
It compress the file in a way that is transparent, I mean you do know that it is compressed, but you can work with it as if it is not, you don't need to decompress it in order to edit it or watch it.
The same go for encryption as long as you log via the same user that encrypted it.

Is there something similar to this in linux generally and or in ubuntu specifically?

znew

ZNEW(1)                                                       General Commands Manual                                                      ZNEW(1)

NAME

       znew -   recompress .Z files to .gz files

SYNOPSIS

       znew [ -ftv9PK] [ name.Z ...  ]

DESCRIPTION

       Znew  recompresses  files  from .Z (compress) format to .gz (gzip) format.  If you want to recompress a file already in gzip format, rename
       the file to force a .Z extension then apply znew.

OPTIONS

       -f     Force recompression from .Z to .gz format even if a .gz file already exists.

       -t     Tests the new files before deleting originals.

       -v     Verbose. Display the name and percentage reduction for each file compressed.

       -9     Use the slowest compression method (optimal compression).

       -P     Use pipes for the conversion to reduce disk space usage.

       -K     Keep a .Z file when it is smaller than the .gz file; implies -t.

SEE ALSO

       gzip(1), zmore(1), zdiff(1), zgrep(1), zforce(1), gzexe(1), compress(1)

BUGS

       Znew does not maintain the time stamp with the -P option if cpmod(1) is not available and touch(1) does not support the -r option.

                                                                                                                                           ZNEW(1)
