MD5 Generator
Message Digest Algorithm 5. Produces a 128-bit (32-character) hash value.
Security Warning: MD5 is no longer considered secure for cryptographic signatures or password hashing as it is vulnerable to collision attacks. It is still commonly used for file integrity checks (checksums) where intentional tampering is not a concern.

What is MD5?
MD5 (Message-Digest algorithm 5) is a widely used cryptographic hash function that produces a 128-bit hash value. Designed by Ronald Rivest in 1991 to replace MD4, it was once a standard for security but is now primarily used for verifying data integrity against accidental corruption.
Properties
- Efficiency: Fast to compute on modern processors.
- Fixed Length: Always produces a 128-bit (32 hex characters) output.
- Common Use: Frequently used for file checksums and simple data identification.
- Cryptographically Weak: Vulnerable to collision attacks where two different inputs produce the same hash.
