MD2 Hash Generator

Generate MD2 hash from text. MD2 produces a 128-bit hash value. Note: MD2 is cryptographically broken and should not be used for security purposes. Requires crypto-js library for full functionality.

What is MD2 Hash?

MD2 (Message Digest 2) is a cryptographic hash function that produces a 128-bit (16-byte) hash value from any input data. Developed by Ronald Rivest in 1989, MD2 was designed for 8-bit computers and generates a unique fingerprint for each unique input.

MD2 processes input data in blocks and creates a fixed-size output regardless of input length. While it was once used for digital signatures and message authentication, MD2 is now considered cryptographically broken and obsolete for security purposes.

Why Use MD2 Hash Generator?

While MD2 is no longer recommended for security applications, it still has limited use cases in legacy system compatibility, historical data verification, and maintaining backward compatibility with older systems that still use MD2 checksums.

Our MD2 hash generator operates entirely in your browser, ensuring your data never leaves your device. This client-side approach provides maximum privacy and security for your sensitive information, even when working with legacy hash algorithms.

The tool is useful for developers maintaining legacy codebases, IT professionals working with older systems, and security researchers studying cryptographic evolution. It helps verify MD2 hashes from historical data or systems that haven't been upgraded.

Common Use Cases

Legacy System Maintenance: Verify MD2 checksums in older applications that haven't been migrated to modern hash functions.

Historical Data Verification: Check MD2 hashes from archived files or legacy databases to ensure data integrity.

Cryptographic Research: Study the properties and vulnerabilities of MD2 as part of cryptographic algorithm analysis.

Backward Compatibility: Generate MD2 hashes for systems that still require this format for interoperability.

Security Audits: Identify and flag MD2 usage in systems that need upgrading to secure modern alternatives like SHA-256 or SHA-3.

How to Use MD2 Hash Generator

Using our MD2 hash generator is straightforward: paste or type your text into the input field, and the MD2 hash is generated instantly in real-time. The 128-bit hash appears as a 32-character hexadecimal string that you can copy with one click.

Important Security Note: MD2 is cryptographically broken and should never be used for passwords, digital signatures, or any security-critical applications. For modern applications, use SHA-256, SHA-3, or bcrypt instead. This tool is provided for legacy compatibility and educational purposes only.
