Which of the following algorithms can be used to check the integrity of a file?
Each correct answer represents a complete solution. Choose two.
A.
md5
B.
rsa
C.
blowfish
D.
sha
Explanation:
Any hashing algorithm can be used to get whether any changes have occurred in a file
or not. In this process, hashing algorithm calculates
the hash value of the file specified and a sender sends hash value also with file. Now, a receiver
recalculates the hash value of the file and
matches whether both the hashes are same or not. Since, md5 and sha are the hashing algorithms;
these can be used to check the integrity
of a file.
Answer option B is incorrect. RSA is not a hashing algorithm and it is not used to check the integrity
of a file.
Answer option C is incorrect. Blowfish is not a hashing algorithm and it is not used to check the
integrity of a file.
