NSA Suite A Cryptography explained

NSA Suite A Cryptography is NSA cryptography which "contains classified algorithms that will not be released." "Suite A will be used for the protection of some categories of especially sensitive information (a small percentage of the overall national security-related information assurance market)."

Incomplete list of Suite A algorithms:^[1]

• ACCORDION
• BATON
• CDL 1
• CDL 2
• FFC
• FIREFLY
• JOSEKI
• KEESEE
