CHain of custody is a simple process. As a Communicator at the Department of State, or someone working as an Information Management Specialist, in the Information Processing Center at the a diplomatic post abroad or at an another agency, the chain of custody for a Top Secret cable is as follows. It is logged into a special TS Log that will never the Post - never ever. The names of anyone with knowledge or touching the document will be entered into the log, and initialed - the document will have the classified subject, and classified content removed from the Subject, and all paragraphs on the TERP or SMART system; the communicator's initials will be entered along with the controlling authority "Deleted IAW 5FAM, etc. JC. At the embassy, consulate or "annex" this is mandatory procedures for anything classified on electronic systems, and the log for the occasional if ever TS material. The DoS probably destroys the electronic copy at Main State.
The cryptographic component can be understood as hash's controlled under the Communications Security Branch.
If the SDNY Office or NYPD has this information, it may well have been painstakingly rendered unusable.
The decision was made a long time ago by a very corrupt socialist named Obama that to be damned with Hillary and not touch her - she is the queen of poison in the DNC. She was both a drunkard while serving as SecState and "fabulously celebrated as someone gender-challenged by the adorning throngs" with the corridors and hallways on the 7th Floor.
