pls help $(1$ point$)$ In this problem we explore the relationship between password length and cryptographic security.

Suppose a password consists of $11$ ASCII characters. You can review the ASCII characters here.. There are exactly $2^7=128$ ASCII characters; we will

assume every character in the password is ASCII $($non$-$printing characters are allowed$).$

What is the size of the keyspace that consists of passwords of this form?

What is the equivalent key length in bits?

Assuming that you could check one password every ${10}^{-8}$ seconds, what is the

worst case running time for cracking this password by brute force search $($in days$)?$

characters from the keyboard. What is the key length in bits in this case?

Now assume that the user used only $26$

to break this weaker password? You can't round to the nearest day here $--$ be as exact as possible.

How many days, in the worst case, would it take

only $26$ characters, how long is the shortest password that achieves $198$ bits of security?
