Important data encryption

So…

I have following situation:
I have to store small .txt file securely (extremely sensitive!) and have it backed up.

And with regular storage on my PC there is no issue, so it is with backup.

I think is it enough to use regular 2GB flash (or SD) encrypted by LUKS for this? This flash will be used only as storage so it is not supposed to have constant writes.

If LUKS not enough, should I put this file inside veracrypt or picocrypt-ng before uploading to flash?

If you are interested what is this file: my PGP key that I use to sign official documents and my crypto seeds. So yeah, it is EXTREMELY sensitive.

My suggestion would be to create a KeePassXC database and store the PGP key as a file attachment in a database entry.

If the key is ASCII armored, you could also store the key in the notes field of a database entry.

I do something similar.
