Coding a Message Digest Algorithms aka Hashing algorithm in Java: SHA-256, MD5, and MD2

In this video, we dive deep into the world of message digest algorithms in Java. Message digest algorithms in java play a crucial role in ensuring data integrity and security by producing a unique hash value (digest) for a given input message. We explore various popular hashing algorithms in java including SHA-256, MD5, MD2, and even delve into the concept of SSHA-256 (Salted SHA-256).
SHA-256 (Secure Hash Algorithm 256-bit): We start by understanding SHA-256, a widely used cryptographic hash function that generates a 256-bit hash value. SHA-256 is known for its strong security properties, making it ideal for applications requiring high-level data integrity checks.
MD5 (Message Digest Algorithm 5): Next, we explore MD5, an older but still relevant hash function that produces a 128-bit hash value. While MD5 was once widely used, it's now considered less secure due to vulnerabilities such as collision attacks. Nonetheless, it's valuable to understand its workings for historical and educational purposes.
MD2 (Message Digest Algorithm 2): We also take a look at MD2, another older hash function that generates a 128-bit hash value. MD2 has largely been replaced by more secure algorithms like SHA-256, but understanding its principles contributes to a comprehensive knowledge of hash functions.
SSHA-256 (Salted SHA-256): Finally, we discuss SSHA-256, which combines the strength of SHA-256 with the concept of salting. Salting involves adding a unique random value (salt) to the input message before hashing, enhancing security against pre-computed hash attacks.
