Abstract: A producer system may insert an encrypted value in a field in a message, where the message is associated with a schema that specifies a public key used to encrypt the encrypted value of the field and further specifies a type of an unencrypted form of the encrypted value, insert one or more unencrypted values in one or more fields in the message, and send the message to an external computing system. A consumer system may receive the message, determine, based at least in part on the public key specified by the schema, a private key associated with the public key, and decrypt, using the private key, the encrypted value of the field into the unencrypted form of the encrypted value.

Abstract: A computing system may receive a message that includes message data and a schema. The message data may include values associated with fields. The message may include a plurality of rules. Each of the plurality of rules may specify a respective one or more fields from a plurality of fields associated with the message and a respective action from a plurality of actions to perform on the values associated with the respective one or more fields. One or more of the plurality of rules may specify one or more output values that are associated with one or more output values resulting from performing one or more actions from the plurality of actions. In response to receiving the message, the computing system may perform the plurality of rules to generate the one or more output values associated with the one or more output fields.
