Can somebody help me understand the joke here? :(
Is it that 3DES doesn't have a 168-bit option?
I guess the main point is that this not how one would mask an ip. An ip is masked by redirecting traffic via some intermediate server(s).
Once she encrypts an ip, what does she do, she sends the string via email to colleagues?
This is how I understand it... But I might be very wrong
I guess I foolishly assumed she was doing her own encryption over https or something (I have no idea if that's even possible. I've taken one network security class)
HTTPS is content encryption (and in part authentication of the server-side if you think CA's are trustworthy), and resides at network layer 7 (application level). The IP is a destination address at network layer 3, used to send packet PDU's (which contents may be encrypted by the layers above in the stack). If you garble (by f.ex. "encrypting") the IP address that you will be receiving response packets at, you're just not going to receive any packets.
Pretty much spot on
Encrypting your IP address would be like encrypting your mailing address. Like, ok buddy, but you're not going to be able to use that to receive any mail so not sure what your goal is -- you're still going to have to use your plain address if you want to receive anything.
3des isn't secure. Even at 168bit. I'm not sure what this is from though, but it was only like 8 years ago that it was announced to be insecure.
