I am attempting to automate a process that decrypts files. The files are 
encrypted with my key which has a passphrase. I have determined I can use the 
"--passphrase-file" option to get the passphrase of my key. In the gpg 
documentation at 
https://www.gnupg.org/documentation/manuals/gnupg/GPG-Esoteric-Options.html, 
under "--passphrase-file file" it says "Don't use this option if you can avoid 
it", but I can't find any alternative solution in the documentation. I found 
one blog that says to just remove the passphrase, however I'd like to preserve 
the passphrase. Do you have any recommendations where I can have a passphrase 
but still use it in an unattended fashion that is secure?
