A cybersecurity expert says that Hunter Biden's email regarding former vice president and Democratic presidential nominee meeting with a Ukrainian businessman is authentic.
Earlier this month, the New York Post reported that Rudy Giuliani, President Donald Trump's personal lawyer, handed over a copy of a laptop's hard drive to the outlet. Giuliani insisted that the laptop belonged to Hunter, and was handed over by a Wilmington, Delaware, computer repair shop owner.
The former vice president's presidential campaign has denied any involvement in the alleged meeting.
Neither Hunter nor Joe have issued remarks on the authenticity of the emails obtained from the laptop or its hard drive at the time of this reporting.
What are the details?
On Thursday, The Daily Caller News Foundation reported that Robert Graham — founder of cybersecurity firm Errata Security out of Georgia — said he was able to confirm the authenticity of Hunter's email regarding his father, Joe, and an executive at Burisma Holdings.
The outlet reported that Graham was able to use cryptographic signature information found in the email's metadata in order to verify that the message — purportedly from Ukrainian businessman Vadym Pozharsky to Hunter, who thanked the former vice president's son for inviting him to Washington, D.C., and providing "an opportunity to meet your father and spent [sic] some time together" — was legitimate and authentic.
The investigative report also revealed that Graham used DomainKeys Identified Mail — or DKIM signature — to verify with a private key on Google servers that the sender and recipient as well as the content of the email were not changed in an attempt to fabricate a fake message.
The outlet reported, "Graham, who has been cited as a cybersecurity expert in The Washington Post, the Associated Press, Wired, Engadget and other news and technology outlets, told the DCNF that he used a cryptographic signature found in the email's metadata to validate that Vadym Pozharsky, an advisor to Burisma's board of directors, emailed Hunter Biden on April 17, 2015. Graham used the DKIM signature within the email to verify with a private key on Google's servers that the sender, recipient, subject, date and body of the message that the DCNF obtained from Giuliani were unchanged from when the email was originally sent in April 2015."
"Graham previously told the DCNF that emails sent from Gmail, such as Pozharski's message to Hunter Biden, can be 'absolutely verified beyond a shadow of a doubt' by testing its contents against the unique DKIM signature found in its metadata," the outlet added.
Graham told the outlet, "[C]ommitting criminal hacking doesn't make true information any less true, so no matter how illegitimately they gathered emails, the contents are provably legitimate."
