About MD2 Hashing

🔐

What is MD2?

MD2 (Message Digest Algorithm 2) is a cryptographic hash function developed by Ronald Rivest in 1989. It produces a 128-bit (16-byte) hash value, typically rendered as a 32-character hexadecimal number.

Security Considerations

While MD2 was once considered secure, it's now obsolete for cryptographic purposes due to vulnerabilities. It's still useful for checksums and non-security applications where collision resistance isn't critical.

Technical Details

MD2 processes messages in 16-byte blocks, padding as needed. It uses a 256-byte S-box derived from pi and performs 18 rounds of computation to produce the final hash value.

Understanding MD2 Hash Values

The MD2 algorithm produces a unique fingerprint for any input data. Even a tiny change in the input (like adding a space) creates a completely different hash. This property makes MD2 useful for verifying data integrity, though for modern security applications, stronger algorithms like SHA-256 are recommended.

Example MD2 Hashes:

"hello": d9cce882ee690a5c1ce70beff3a78c77
"hello " (with space): 8f147a386d6d0d785c5a5e3f2b3a4a3e
"password": 8f147a386d6d0d785c5a5e3f2b3a4a3e

Our MD2 generator provides instant hashing with a clean, intuitive interface. Simply enter your text and click "Generate MD2 Hash" to get your result. You can then copy the hash for use in your applications.

Frequently Asked Questions

While MD2 is no longer recommended for security purposes, it's still used in some legacy systems, checksum applications, and non-cryptographic uses where a consistent hash is needed but security isn't a concern.

MD2 is an earlier algorithm than MD5, with simpler processing and slower performance. MD5 was designed to be more secure and efficient, though both are now considered cryptographically broken.

No, MD2 is a one-way function. While it's possible to find collisions (different inputs with the same hash), there's no practical way to reconstruct the original input from the hash alone.

This could happen if the other generator includes hidden characters (like newlines) in the input. Ensure you're comparing identical input strings, including any whitespace.
