Which of the following algorithms is used by MD5?

• Block cipher algorithm
• Asymmetric encryption algorithm
• Cryptographic algorithm
• Hashing algorithm 

EXPLANATION

MD5 which stands for Message Digest algorithm 5 is a widely used cryptographic hash function that was invented by Ronald Rivest in 1991. The idea behind this algorithm is to take up a random data (text or binary) as an input and generate a fixed size “hash value” as the output. The input data can be of any size or length, but the output “hash value” size is always fixed.
