Thank you very much, I appreciate your help.

It cannot be encrypted in memory. Oh, a whole file can be, if the whole file is loaded at once, but the buffer holding the info currently being used can't be, so there will always be a point of vulnerability. Invent a good way to obscure every byte 100% of the time, and you will be rich, rich, rich!

There are a few things that can almost do what I think you are asking, but the need to do so seems a little extreme.

Uh, some things encrypt the whole disk, but so far, disk-based encryption hasn't been too satisfactory. Some partition-level encryption is available. This may be a bit vulnerable when errors occur, meaning if the wrong bits get flipped, all your data goes bye-bye. (That is true of some file systems, and a lot of compression methods, as well.)

Uh, cryptsetup  cryptmount.  Maybe the ecryptfs file system?
