Redvers Encryption Device

The Redvers Encryption Device architecture centers around providing AES encryption and decryption capabilities directly within COBOL applications running on z/OS, z/VM, and zVSE/VSEn. The core components are the `RCENCRYP` and `RCDECRYP` COBOL subroutines, which are distributed as source code. These subroutines are integrated directly into the COBOL application's build process.

The communication between the application and the encryption device occurs through standard COBOL `CALL` statements. For example, `CALL 'RCENCRYP' USING INPUT-DATA, OUTPUT-DATA, KEY` invokes the encryption routine. The device operates within the application's memory space, eliminating the need for external network communication or specialized hardware.

Configuration, such as setting the AES key length, is performed by modifying the COBOL source code and recompiling the application. The device relies on the underlying operating system for security features. Competing products may offer REST APIs or hardware-based encryption, but Redvers provides a source code solution for maximum control and customization.

Monitoring and logging depend on the COBOL application's capabilities and the OS.
