Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many bits is the effective length of the key used in the Message Digest five (MD5) algorithm?
A
168
B
128
C
56
D
64
Explanation: 

Detailed explanation-1: -The MD5 message-digest hashing algorithm processes data in 512-bit strings, broken down into 16 words composed of 32 bits each. The output from MD5 is a 128-bit message-digest value.

Detailed explanation-2: -MD5 (Message-Digest algorithm 5) is a widely used cryptographic hash function that results in a 128-bit hash value.

Detailed explanation-3: -The hash size for the MD5 algorithm is 128 bits.

Detailed explanation-4: -An MD5 hash is 16 bytes. Each MD5 hash looks like 32 numbers and letters, but each digit is in hexadecimal and represents four bits. Since a single character represents eight bits (to form a byte), the total bit count of an MD5 hash is 128 bits.

Detailed explanation-5: -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.
