generatePad$($seed$,$ k$,$ l$)$

returns a pseudo$-$random list of $1$ s and $0$ s $,$ generated by an $[N,k]$ LFSR$,$ where $N=$ length of seed

parameters:

seed : list of $1\text{'}$s and $0\text{'}$s

k: int $,$ tap position

I : int, length of the sequence to be generated

return type: list of $1\text{'}$s and $0\text{'}$s

encrypt $($message$,$ seed, k$)$

takes a string message and returns it as an encrypted string using an $[$N$,$ k$]$ LFSR

parameters:

message : string of characters from Base$64$ set

seed : list of $1\text{'}$s and $0\text{'}$s

k : int, tap position

return type: string

heres hwo they should be tested: $|$ THE EXPECTED RESULT MUST MATCH THE RESULT
