MD5 Hash is a widely used cryptographic hash function that produces a 128-bit hash value from input data. It’s commonly employed for data integrity checks, ensuring that files and messages have not been altered. Despite its popularity, MD5 is no longer considered secure against intentional tampering due to vulnerabilities discovered over time. It is often used in checksums and data validation processes, particularly in non-security-critical applications. Overall, while MD5 serves its purpose in many contexts, more secure alternatives like SHA-256 are recommended for sensitive data.
