The other thing is that cryptography doesn&#x27;t make a conversation completely private forever.<p>I remember a conference where old crypto algorithms were mentioned. Unbreakable in the 80s or 90s but now trivial to decipher. The speaker implied that both Russia and the US would have carefully recorded and stored all of each other&#x27;s communication and that we can bet that the content of these communications is still interesting today, not just for their historical interest.<p>We live old. Much older than the technologies we use. Now our gvt is doing to us what they would only do to foreign embassies.
