Answer:
c. your friend can hash all possible options and discover your secret.
Explanation:
SHA-256 is a set of hash functions that was designed by the NSA. SHA-2 is considered an upgrade on the set that was its predecessor, SHA-1. A hash is a mathematical function that condenses data in a process of one-way encryption. SHA-256 creates hash algoritms that are considered irreversible and unique. However, one of the properties of hashing algorithms is determinism, which means that any computer in the world would be able to compute a particular hash and get the same answer.
Answer:
Explanation:
The following is written in Python and uses exception handling to do exactly as requested. It then goes adding all of the integer values to an array called num_list and finally adding them all together when the function ends.
def in_values():
num_list = []
while True:
try:
num = input("Input non-zero floating point: ")
num = int(num)
if num == 0:
break
else:
num_list.append(num)
except ValueError:
print("No valid integer! Please try again ...")
try:
num = input("Input non-zero floating point: ")
num = int(num)
break
except ValueError:
break
sum = 0
for number in num_list:
sum += number
return sum
