Java MD5 HackerRank Solution

Hello Programmers, In this post, you will know how to solve the Java MD5 HackerRank Solution. This problem is a part of the HackerRank Java Programming Series.

One more thing to add, don’t directly look for the solutions, first try to solve the problems of Hackerrank by yourself. If you find any difficulty after trying several times, then you can look for solutions.

Java MD5 HackerRank Solution

Objective

MD5 (Message-Digest algorithm 5) is a widely-used cryptographic hash function with a 128-bit hash value. Here are some common uses for MD5:

• To store a one-way hash of a password.
• To provide some assurance that a transferred file has arrived intact.

MD5 is one in a series of message digest algorithms designed by Professor Ronald Rivest of MIT (Rivest, 1994 ); however, the security of MD5 has been severely compromised, most infamously by the Flame malware in 2012. The CMU Software Engineering Institute essentially considers MD5 to be “cryptographically broken and unsuitable for further use”.

Given an alphanumeric string, S , denoting a password, compute and print its MD5 encryption value.

Input Format

A single alphanumeric string denoting .

Constraints

• String  consists of English alphabetic letters (i.e.,  and/or decimal digits (i.e.,  through ) only.

Output Format

Print the MD5 encryption value of  on a new line.
