1. A system for decryption of one or more payloads, the system comprising: a hardware security module implemented by at least one processor for decrypting encrypted elements of received payloads, the hardware security module operatively connected to at least one decryption server; the at least one decryption server, wherein the at least one decryption server is configured to transmit the particular payload to the hardware security module for decryption of at least one encrypted element; at least one read-only database, the at least one read-only database configured to store authentication data for decrypting encrypted elements of the received payloads; a frontend server operatively connected to the at least one read-only database, the frontend server configured to: 1) retrieve authentication data associated with a particular received payload; and 2) compare the authentication data to the particular received payload to authenticate the particular received payload before the particular received payload is transmitted to the hardware security module; and a master read-only database operatively connected to the at least one read-only database, the master read-only database configured for refreshing the authentication data stored at the at least one read-only database.
