MD6 HASH Generator Online

MD6 hash function generator generates Hash for MD6-128, MD6-256 and MD6-512 using MD6 encryption. Also referred to as Pumpkin Hash.

It will generate 32 hexadecimal for MD6-128, 64 hexadecimal for MD-256 and 128 hexadecimal for MD-512 MD6 hash string whatever the input word/characters count.

Once the MD6 Hash is generated, it's not reversible, it's nearly impossible to decrypt.

  • Step 2: Click on Generate MD6 HASH Online
  • Step 3: Use Copy to Clipboard functionality to copy the generated MD6 hash.

What is MD6 HASH?

MD6 is uses Bottom-up tree-based mode of operation like Merkle tree structure 4-to-1 compression ratio at each node. It's designed by Ronald L. Rivest, Benjamin Agre and many others in 2008.

MD6 did not selected to the second round of the SHA-3 competition.

The MD6 Message-Digest Algorithm is a cryptographic hash function. It uses a Merkle tree-like structure to allow for immense parallel computation of hashes for very long inputs. Authors claim a performance of 28 cycles per byte for MD6-256 on an Intel Core 2 Duo and provable resistance against differential cryptanalysis. The source code of the reference implementation was released under MIT license.

Speeds in excess of 1 GB/s have been reported to be possible for long messages on 16-core CPU architecture.

In December 2008, Douglas Held of Fortify Software discovered a buffer overflow in the original MD6 hash algorithm's reference implementation. This error was later made public by Ron Rivest on 19 February 2009, with a release of a corrected reference implementation in advance of the Fortify Report.

MD6 was submitted to the NIST SHA-3 competition. However, on July 1, 2009, Rivest posted a comment at NIST that MD6 is not yet ready to be a candidate for SHA-3 because of speed issues, a "gap in the proof that the submitted version of MD6 is resistant to differential attacks", and an inability to supply such a proof for a faster reduced-round version, although Rivest also stated at the MD6 website that it is not withdrawn formally. MD6 did not advance to the second round of the SHA-3 competition. In September 2011, a paper presenting an improved proof that MD6 and faster reduced-round versions are resistant to differential attacks was posted to the MD6 website
