What encryption software for long-term archival purposes (Linux + WindowsCygwin & CLI)?

What I want to achieve:

I intend to burn a few dozen of single-layer Blu-Rays, 25GB, M-Discs with data that are precious to me in an encrypted form.

  • The hardware needed: - Blu-Ray writer and the M-Discs, - I already have.

  • I have chosen AES-256 as the encryption method for the data.


Operating systems currently in use/ platforms which has to be supported by the solution:

  • Linux Mint (18)

  • GNU/Linux Debian (9)

  • Windows (10) Cygwin (on Windows 10)

This may or may not change in the future; let's suppose it would change rather than not.


What software would you recommend me to do the storage?

The conditions follow:

  • The data can't be compressed further, so no compression needed.

  • Both Linux and Windows access is needed.

  • Generic Linux and Cygwin access needed.

  • I would rather have individual files encrypted, than for instance one VeraCrypt containter for everything.

  • It should have a CLI (command-line interface) so that I could decrypt it on a headless server too.


I think 7-zip with no compression option could do this job well, but I rather ask before I could make a mistake, I would regret later on.

  • 7-zip is open-source, I compile it myself on my LinuxesI compile it myself on my Linuxes

  • It supports AES-256

  • It has CLI interface


EDIT1:

I forgot to tell you how far to the future I am looking: about 20 years.
