A more thorough explanation:

Name key

A name key is a legal document that contains the real names of individuals associated with pseudonyms in a legal case.

For example, in a court case involving a whistleblower who used a pseudonym to protect their identity, a name key would be created to link the pseudonym to the individual's real name.

Another example would be in a case involving a victim of a crime who wishes to remain anonymous. A name key would be created to ensure that the victim's real name is not disclosed in court documents, while still allowing for the victim to participate in the legal proceedings.

The examples illustrate how a name key is used to link pseudonyms to real names in legal cases. This document is important for protecting the privacy and safety of individuals involved in legal proceedings while still allowing for their participation in the case.
