MD2 is an older 128-bit message digest algorithm defined in RFC 1319. It was designed for 8-bit processors and is now obsolete for cryptographic use.
This page exists for compatibility and debugging when a legacy system still expects MD2 output. For modern security, use SHA-256 or SHA-512 instead, and use password-specific algorithms such as Argon2 or bcrypt for password storage.
How to Use MD2 Hash Generator
Type or paste the text you want to hash
Review the generated MD2 output
Toggle uppercase if a target system expects capital hex
Copy the digest for comparison, fixtures, or legacy compatibility checks
Common Use Cases
- Matching MD2 values from old fixtures or protocol examples.
- Debugging legacy certificate or signature workflows.
- Testing migration code that needs to read old MD2 digests.
- Comparing historical hash outputs during documentation cleanup.
Example Input and Output
Generate an MD2 value from the standard sample input.

The tool encodes input as UTF-8 bytes and runs a browser-side RFC 1319 MD2 implementation. The digest is formatted as hexadecimal with an optional uppercase display toggle. No input is uploaded or stored.
Technical Stack
Variant
RFC 1319 MD2 over UTF-8 input bytes.
Security note
MD2 is included for compatibility testing only. Do not use it for new authentication, signatures, or password storage.
