Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The original message digest algorithm out of the following is ____
A
MAC
B
SHA
C
MD5
D
DSA
Explanation: 

Detailed explanation-1: -MD5 is the Message Digest algorithm 5, created by Ronald Rivest. It is the most widely used of the MD family of hash algorithms. MD5 creates a 128-bit hash value based on any input length.

Detailed explanation-2: -MD5 (Message Digest Method 5) is a cryptographic hash algorithm used to generate a 128-bit digest from a string of any length. It represents the digests as 32 digit hexadecimal numbers. Ronald Rivest designed this algorithm in 1991 to provide the means for digital signature verification.

Detailed explanation-3: -The MD5 message-digest algorithm is a widely used hash function producing a 128-bit hash value.

Detailed explanation-4: -MD5 is quite fast than other versions of the message digest, which takes the plain text of 512-bit blocks, which is further divided into 16 blocks, each of 32 bit and produces the 128-bit message digest, which is a set of four blocks, each of 32 bits.
