Hey there

I have a user that uses an app. with aes-128 bit encryption - from what I have read, it takes billions of years to crack this. Not sure how accurate that is.
One network he connects to via Wi-Fi has winpcap on it.  Anyone know what winpcap would see if messages, say even text messages are sent via aes-128 over this network?
Would it just show that there are in fact encrypted packets? Would it show the application he is using?  Would it show content?  Due to the nature of her communications she wants to make sure she is safe.
What can you guys tell me?
Thanks

They use at least aes-128 if not higher.  From what I know about aes-128 that is secure.

Thanks

Ok...
A sniffer is not something that breaks encryption. It would just record rubbish.

What? No. It is encrypted and sniffers do no magic.

Hey there

I realize they don't do magic, so would it have some type of signature on it showing it was encrypted or the app it is from?  McKnife thanks for your response.  I guess you have a bit of experience with sniffers etc?

Really, - I appreciate what you are sharing with me!
Thanks my friend!

Let me guess where you are really at... ;) You would like to sniff the data and visualize that it is encrypted so that your user can sleep well?
