Yeah, that supports handling encrypted files, but the question is if org indexes such files to handle interlinking, file completion, agendas and stuff.
I guess it doesn't.
I guess it doesn't.
for example:
encryptedfile.org.gpg
* someheading
:PROPERTIES:
:ID: bf15277c-8505-4888-9497-a5533829217d
:END:
EOF
otherfile.org
[[id:bf15277c-8505-4888-9497-a5533829217d][this link will work]]
EOF
I'm not sure about agenda and file completion though.
