Methods, systems, and storage media for relaying a message through an offline mesh network are disclosed. Exemplary implementations may: relay messages by changing device names within a network; generate, at an initial node, an encoded message comprising a payload, an account identifier for the initial node, and an account identifier for the destination node; relay the encoded message through one or more intermediary nodes; determine, by each of the one or more intermediary nodes, whether device names in the vicinity are encoded messages and; in response to the determining, deliver the encoded message to the destination node; and cause display of the encoded message through the destination node.

Offline mesh messaging network with bluetooth broadcasting

Various aspects of the subject technology relate to systems, methods, and machine-readable media for providing encryption of data with data separation. Various aspects may include performing determining a request payload for a communication from a client device. Aspects may also include creating a first reference data object for a first subset of data fields of the request payload. Aspects may also include creating a second reference data object for a second subset of data fields. Aspects may also include replacing a first value of the first subset with a first reference value. Aspects may include replacing a second value of the second subset with a second reference value. Aspects may include encrypting a response payload with the first reference data object and the second reference data object in an encrypted text-based structured data file format with a cryptographic key.
