Verifying the integrity of data can be done by which of the following____?
SHA-1
3DES
RSA
AES
SHA-1 is a Hashing algorithm. The basic function of Hashing is to maintain integrity of data. Hence, SHA-1 is the right answer. 3DES, AES, and RSA are Encryption algorithms. (The original question only had "SHA" which is not a hashing algorithm. SHA-1 or SHA-2 would have been correct as Hashing algorithms. "SHA" is not.)
