To provide integrity of data, hashing is often used. Which of the following is a commonly used 128-bit hash digest?
|
|
SHA-1
|
|
|
MD-5
|
|
|
CRAMMD5
|
|
|
SHA-256
|
Explanation:
Detailed explanation-1: -The MD5 (message-digest algorithm) hashing algorithm is a one-way cryptographic function that accepts a message of any length as input and returns as output a fixed-length digest value to be used for authenticating the original message.
Detailed explanation-2: -Correct Option: C Q and S only. Both SHA-1 and MD5 can be used to generate a message digest.
Detailed explanation-3: -SHA-256 and MD5 both generate the message digest.
Detailed explanation-4: -RSA is also used to decrypt the encrypted message by same RSA algorithm. Data encryption standard (DES) is a block cipher that encrypts data in blocks of size 64 bits each. RSA and DES do not allow generating message digests. 16-Mar-2023
