Unmanaged secure inter-application data communications

A non-transitory computer-readable medium embodying program code for secure data sharing between applications that, when executed by a computing device, directs the computing device to at least:

• obtain, by a first application executed by the computing device, an identity certificate associated with the first application, wherein the identity certificate comprises:
• a unique identifier associated with the computing device, and a public key associated with the first application;
• authenticate the first application with a management computing environment, over a computer network, using the identity certificate associated with the first application and the unique identifier associated with the computing device;
• obtain a plurality of public keys from the management computing environment in response to authentication of the first application with the management computing environment, the plurality of public keys being associated with a plurality of other applications known to the management computing environment to be executing on the computing device;
• cause the plurality of public keys obtained from the management computing environment to be stored in a key store of the computing device;
• cause, by the first application, an encrypted data package to be generated using a public key associated with a second application among the plurality of other applications;
• and
• cause, by the first application, the encrypted data package to be communicated to the second application through an inter-application communication process.

A computing device for secure data sharing between applications, comprising:

• a memory device configured to store computer-readable instructions thereon;
• and
• at least one processing device configured, through execution of the computer-readable instructions, to direct the computing device to at least:
• obtain, by a first application executed by the computing device, an identity certificate associated with the first application, wherein the identity certificate comprises:
• a unique identifier associated with the computing device, and a public key associated with the first application;
• authenticate the first application with a management computing environment, over a computer network, using the identity certificate associated with the first application and the unique identifier associated with the computing device;
• obtain a plurality of public keys from the management computing environment in response to authentication of the first application with the management computing environment, the plurality of public keys being associated with a plurality of other applications known to the management computing environment to be executing on the computing device;
• cause the plurality of public keys obtained from the management computing environment to be stored in a key store of the computing device;
• cause, by the first application, an encrypted data package to be generated using a public key associated with a second application among the plurality of other applications;
• and
• cause, by the first application, the encrypted data package to be communicated to the second application through an inter-application communication process.
