Regarding the items discussed in the referenced memos, it appears that a further interpretation is required. -On the subject of cryptosystems, we cannot give wholesale approval for their release, but if the crypts have been previously blown or exposed they can be released. There may be cases in which if the crypto has been retired, does not relate to existing or another project they can not contain a valid data, or any other project or does not contain any valid which are related to a series (ZZBOATZ/ZBOATZI), etc.).

Summary  
The document details discussions from 1993 to 1998 regarding the release of JFK assassination records under the 1992 Presidential Records Act. Central concerns included protecting operational security by redacting cryptonyms (coded names) and sensitive terms like ISOLATION, ISOTROPIC, and ISOSOMOS, which were linked to locations under military cover. The CIA emphasized risks of exposing Soviet intelligence activities, particularly through the cryptonym JUDECANTER (later IJDECANTER), associated with Sergei PAPUSHIN, a defector whose family remained in Russia. Proposals included substituting fictitious names for sensitive cryptonyms and withholding details that could compromise U.S. counterintelligence efforts or harm foreign relations. The Assassination Records Review Board (ARRB) and CIA Directorate of Operations (DO) were key entities managing these release guidelines.
