Computer Security & Cryptography
Some of Dave'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 reliable and verifiable transmission of data and messages, centered around the idea of an "unalterable, encrypted audit log system".

Bitcoin involvement
See also: Satoshi Nakamoto and Bitcoin
In 2011 Kleiman founded the company W&K Info Defense Research LLC (“W&K”) in Florida[5], allegedly to mine bitcoins.

On December 2015 Gizmodo reported that Dave Kleiman may have been involved in the invention of bitcoin based on information uncovered in several leaked documents.[6]

In May 2016, The Economist article had Craig Steven Wright claiming he (under the pseudonym of Satoshi Nakamoto) and Dave Kleiman were behind the invention of bitcoin.[7] In February 2018, a brother of Dave 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 more than $5,118,266,427.50 worth of bitcoin, claiming Wright defrauded the estate of bitcoins and intellectual property rights.[5][8] The estate alleged that Kleiman was one of the early bitcoin pioneers and worked with Craig Steven Wright on its establishment as a cryptocurrency.[9] The estate also alleges that on January 12, 2009, Kleiman, Wright and two other people performed a recorded bitcoin transaction.[5] The lawsuit claims that between 2008 and 2013 Kleiman and Wright mined over a million bitcoins.[5] According to Craig Wright, Kleiman lost money due to US government seizing of Costa Rica-based Bitcoin exchange called Liberty Reserve leading to Kleiman's poverty.[10]

---------------------------------------------
La fase de descubrimiento de este caso ha comenzado y la Última transcripción de la cual, se puede encontrar aquí. Con fecha 26 de marzo de 2019, ésta transcripción ORIGINAL revela algunas cosas muy interesantes:

"SRA. MCGOVERN: es la posición del Dr. Wright, Señoría, Dave Kleiman ayudó a editar el protocolo relacionado con Bitcoin pero no creó Bitcoin"

"Señoría, los demandantes han alegado que en el 2008 el acusado (Craig Wright) y Dave Kleiman se asociaron, y entiendo que es discutible el término, para la creación del Bitcoin, tambien minar Bitcoin, y ademas crear la propiedad intelectual basada en Blockchain. "

Este caso acaba de empezar en Florida, así que hay mucha más información que sera revelada.

Esta transcripción es sólo un día, en una larga serie de fechas de descubrimientos y juicios, para un caso, que se viene llevando más de 6 años. Este caso parece estar llevándose a cabo de manera prolongada, debido a la lenta tasa de producción de documentos por parte del equipo legal de la representación de Kleinman.
