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,
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?
