About MD5

MD5 (Message Digest 5) is a widely used cryptographic hash function that produces a 128-bit hash value. It was designed by Ronald Rivest in 1991 as an improvement over MD4. Although MD5 was once considered secure, it has since been found to have significant vulnerabilities, including the ability to generate collision attacks, making it unsuitable for cryptographic purposes.

Despite its security flaws, MD5 is still used in non-secure applications such as file integrity checks, error-checking systems, and legacy systems where compatibility is required. It's important to note that MD5 should not be used for applications requiring strong security, such as password hashing or digital signatures.
