I have to say, this is something I thought about. While some newer CPUs |
65 |
have even been talked about on this list, I don't recall this one being |
66 |
included, or the one I currently use. Given its age, I would think it |
67 |
would be exposed if it was hackable or had a backdoor, but one never |
68 |
knows. As to country it was made in, I don't trust any of them really. |
69 |
The NSA is just as bad at snooping as any other country. Well, some |
70 |
such as China may be worse but if it has a backdoor, it has a backdoor. |
71 |
If one Govt or group knows about it, they all will at some point and |
72 |
will exploit it for their own means. |
73 |
|
74 |
I might add, this is why I'd love to see encryption done by a group that |
75 |
is not infiltrated by a Govt agency, education system etc and is open |
76 |
source the the point that a backdoor is impossible. That would be a |
77 |
very tall order tho. Sometimes people with bad intentions get in |
78 |
despite all the effort to exclude them. |
79 |
|
80 |
This is one reason I'm considering splitting off certain directories |
81 |
that are encrypted. Thing is, is there one that isn't already hackable |
82 |
by groups such as the NSA or folks in China etc?? Would we really ever |
83 |
know if they could or not?? |
