Q: problem with a discrete logarithm/cyclic groups example... can anyone clarify this concept for me?

Andrea FarnetiI was watching this really short video about the discrete logarithm example: https://www.youtube.com/watch?v=SL7J8hPKEWY and at 0:38 they show all the possible values that you can get if p = 17 and g = 3. At 1:00 they state that the solution is equally likely to be any integer between 1 and 17. M...

Q: Why is possible to encrypt multiple messages within the same stream in AES

dmtrs18I have a standard random key and IV. Then I am creating a cipher using these keys and iv and then encrypting a specific message. Later on, if I try to encrypt another message with the same cipher(which means same key and iv) it is possible. What is the explanation for this?

I think that "last seen" this year would be useful. I'm more likely to answer something if I know the person would get something out if it. I realize that the community would get something out of it anyway, but there seems to be a psychological feel good factor.
...and I just realized that I never googled myself.

Some suggested that should be optional since once you visit your profile, it is there.
