A system for decryption of payloads, the system comprising: a frontend server operatively connected to a first, second and third read-only database, the frontend server configured for: a) receiving a plurality of payloads from one or more third parties, wherein each of the payloads includes at least one encrypted element; b) retrieving authentication data from the first, second and third read-only databases; c) comparing the authentication data with each of the plurality of payloads to determine whether one or more of the payloads of the plurality of payloads has been compromised; d) upon determining that one or more of the payloads of the plurality of payloads has not been compromised, transmitting the one or more payloads of the plurality of payloads to a hardware security module for decryption of the at least one encrypted element; the first, second and third read-only databases operatively connected to the frontend server and configured for storing read-only authentication data for use in determining whether payloads have been compromised; a master read-only database operatively connected to the first, second and third read-only databases and a read/write backend database, the master read-only database configured for receiving the authentication data from the read/write backend database and refreshing the authentication data at each of the first, second and third read-only databases; and the hardware security module operatively connected to the frontend server, the hardware security module configured for decrypting the one or more payloads of the plurality of encrypted payloads based on an encryption key and transmitting the decrypted one or more payloads to the one or more third parties. a frontend server operatively connected to a first, second and third read-only database, the frontend server configured for: a) receiving a plurality of payloads from one or more third parties, wherein each of the payloads includes at least one encrypted element; b) retrieving authentication data from the first, second and third read-only databases; c) comparing the authentication data with each of the plurality of payloads to determine whether one or more of the payloads of the plurality of payloads has been compromised; d) upon determining that one or more of the payloads of the plurality of payloads has not been compromised, transmitting the one or more payloads of the plurality of payloads to a hardware security module for decryption of the at least one encrypted element; the first, second and third read-only databases operatively connected to the frontend server and configured for storing read-only authentication data for use in determining whether payloads have been compromised; a master read-only database operatively connected to the first, second and third read-only databases and a read/write backend database, the master read-only database configured for receiving the authentication data from the read/write backend database and refreshing the authentication data at each of the first, second and third read-only databases; and the hardware security module operatively connected to the frontend server, the hardware security module configured for decrypting the one or more payloads of the plurality of encrypted payloads based on an encryption key and transmitting the decrypted one or more payloads to the one or more third parties.
