MD4 Hash Generator
Generate MD4 hashes instantly in your browser.
What is MD4?
MD4 (Message Digest Algorithm 4) is a cryptographic hash function developed by Ronald Rivest in 1990. It produces a fixed-length 128-bit hash represented as 32 hexadecimal characters. MD4 is considered cryptographically broken and should only be used for legacy compatibility purposes.
How It Works
Enter Text
Type or paste the text you want to hash.
Generate Hash
Click Generate MD4 Hash to create a 128-bit digest.
Copy Result
Copy the generated MD4 hash for comparison or verification.
About MD4 Hashing
MD4 (Message Digest Algorithm 4) is a hashing algorithm developed by Ronald Rivest in 1990. It produces a fixed-length 128-bit hash represented by 32 hexadecimal characters regardless of the size of the original input.
How It Works
MD4 processes data in blocks and generates a unique digital fingerprint. Even a small change in the input produces a completely different hash value. Hashing is a one-way operation and cannot be reversed to recover the original text.
Common Use Cases
- Legacy file integrity verification.
- Checksum generation for older systems.
- Compatibility with legacy authentication protocols.
- Data fingerprinting and comparison.
- Historical cryptographic research.
- Legacy software and archive verification.
Privacy & Security
- All hashing is performed locally in your browser.
- No text is transmitted to any server.
- MD4 is considered cryptographically broken and insecure.
- Use SHA-256, SHA-384, or SHA-512 for modern security applications.
