I'm wondering why. Also, when I do a "gpg -h", "--passphrase" doesn't show up as one of the options. Is this like a secret option or something? So I thought this would help, but unfortunately it didn’t. I’m wondering why. Also, when I do a “gpg -h”, “–passphrase” doesn’t show up as one of the options.

The information about the files will be protected, and the script should still run normally.

It is actually bound to how the process calls his conf files ,i.e at the beginning , in the loop ... 3) You can even recompile squid with some crypting lib. and change all calls to read file to be proceeded by a decryption function. 4) No body but the root should have the root pass , other users must be in specific groups that enable them to do some stuff that normally only the root can do and hence avoid giving them the root pass. 1) Unless the app is aware of the encryption , you cannot encrypt such .conf files.
