Question

In a secure Hash algorithm, the output is an encrypted message digest. True False QUESTION 9 SHA-1 gives 160-bit secure hash. Let's assume that a successful brute force attack is possible by trying 24(160/3) combinati ons. If we do a double hash (as is done in Encase tool for forensics), the input is the secure hash of the message and the output is also another secure hash. Comparing this with SHA-2 using 256 bits, we can say OSHA-256 is stronger because it requires 2 (256/3) brute force combinations, while SHA-1 still needs 24(160/3) combinations double SHA-1 is stronger because it requires twice the 24(160/3) combinations. broken first stage, there are 2 (160/3) brute force attempts may be needed they are roughly equal and there was no need for the 256 version. Odouble SHA-1 is stronger because it requires about 24(160/3) x 2 (160/3) maximum combinations becaue for each QUESTION 10 The birthday attacks are called so because we can only have 365 birthdays (oh well, excluding 2/29). So, if there are 366 people in a place at least two of them have the same birthday-thus causing collision(s). Same things happens in hash algorithm. The people in birthday attack is the same thing as hash in the hash algorithm input in the hash algorithm. the algorithm in hash algorithm. the key

Q8) In a secure hash algorithm, the output is an encrypted message digest.

Answer)
True.
A SHA - secure hash algorithm is known as a cryptographic has function which takes input and then process it to produce an encrypted message digest which is rendered typically as a hexadecimal number.
