The act of encrypting things *always* makes them (seem) more interesting.
You can use encryption to keep secrets, but, in using encryption, may let others know that you even have a secret at all.
So, the very best kind of encryption is both un-openable without a very large securely transported key AND not obviously (or even unobviously) encrypted at all.
@futurebird Part of the solution is just to encrypt by default. Almost every web page access uses https now, disks on computers and phones are encrypted. There are still plenty of gaps but if encryption is the default it isn't suspicious.
