Around July 2013: Clinton’s emails still are not encrypted.

According to an unnamed Platte River Networks (PRN) employee, Clinton’s server has encryption protection to combat hackers, but the individual emails have not been protected with encryption. With PRN taking over management of the server in June 2013, this employee will later tell the FBI that “the Clintons originally requested that email on [Clinton’s] server be encrypted such that no one but the users could read the content. However, PRN ultimately did not configure the email settings this way, to allow system administrators to troubleshoot problems occurring within user accounts.” (Federal Bureau of Investigation, 9/2/2016)
