I am using symmetric encryption, so the usual public/private keys are not 
relevant
in this situation.

Unless I too have missed something, then I don't think this applies 
to the symmetric case.

But thanks for the suggestion.

In passing, for further background, all of this is happening on an
mounted encrypted volume. I am guarding against malware that might be able
to read the temporarily decrypted file. At least the other files on the mounted
volume are protected by the second level of gpg symmetric encryption.
Rather like a password manager that handles more general files with the
manager database only on the (temporarily mounted) encrypted volume.
