Craig Steven Wright claims Kleiman was involved in the invention of Bitcoin, and that Wright himself was Satoshi Nakamoto, Bitcoin's main inventor. Wright's claims are widely regarded as a hoax.
At the age of 21, Kleiman was named United States Army Soldier of the Year. He received the Army Achievement Medal and a commendation signed by the Secretary of the Army. The commendation said in part, "Appearance, knowledge of general military subjects, current events and other subjects covered coupled with your strong dedication to duty, never failed to produce anything but outstanding results."
After distinguished service in the Army, Kleiman returned to his hometown and became a sworn law enforcement officer for the Palm Beach County Sheriff's Office (PBSO). In 1995, a motorcycle accident left him paralyzed, requiring the use of a wheelchair. The life-altering disability did not slow him down for long. He continued working at PBSO and attained the rank of detective. He also worked as a System Security Analyst in the Computer Crimes Division and helped configure the Computer Forensics Lab. Kleiman went on to work at a number of high tech companies before becoming a partner in a computer forensics business. Kleiman died in his home in April 2013 seemingly of natural causes related to complications from a MRSA infection.
Computer security & cryptography

Some of Kleiman's most notable work took place at S-doc where his role was Chief Information Security Officer. While there he developed a Windows encryption tool that surpassed NSA, NIST, and Microsoft Common Criteria Guidelines. This technology was used at NASA, U.S. Dept. of Treasury, Office of the Inspector General, and the US Post Office. Cryptography was routinely used at S-doc to develop several products, broadly aimed at the reliable and verifiable transmission of data and messages, centered around the idea of an "unalterable, encrypted audit log system".
Kleiman was also a regular contributor to Cryptography and Security mailing lists where discussions included technical aspects of cryptosystems and the politics of cryptography. Kleiman was a long-time member of the same Metzdowd Cryptography mailing list where Satoshi Nakamoto first announced Bitcoin on Oct. 31, 2008.
Kleiman held the following certifications: Information Systems Security Management Professional (ISSMP), Information Systems Security Architecture Professional (ISSAP), Certified Information Systems Security Professional (CISSP), Certified Information Forensics Investigator (CIFI), Certified Information Security Manager (CISM), Certified Anti-Terrorism Specialist (CAS), Certified Computer Examiner (CCE), a Microsoft Certified Systems Engineer (MCSE).
For multiple years, Kleiman was awarded Microsoft MVP for Windows – Security.
Alleged Bitcoin involvement
In December 2015 Gizmodo reported that Dave Kleiman may have been involved in the invention of the digital currency Bitcoin, based on documents sent to the press concerning Craig Steven Wright's claim to be Satoshi Nakamoto, the inventor of bitcoin. Wright repeated the claim to The Economist in May 2016. Wright's claims about the creation of Bitcoin are widely considered extremely dubious, and possibly a hoax.
In February 2018, Dave Kleiman's brother Ira, the executor of his estate, initiated a lawsuit in the U.S. District Court for the Southern District of Florida on behalf of the Kleiman estate against Wright over the rights to between 550,000 and 1,100,000 bitcoins, claiming Wright defrauded the estate of bitcoins and intellectual property rights. The estate alleged that Kleiman was one of the early bitcoin pioneers and worked with Craig Steven Wright on its establishment as a cryptocurrency.
