Redvers Encryption Device Modernization Guide

The Redvers Encryption Device provides AES encryption and decryption capabilities for COBOL applications running on z/OS, z/VM, and zVSE/VSEn. It consists of two COBOL subroutines: RCENCRYP for encryption and RCDECRYP for decryption.

The device is distributed as COBOL source code, allowing direct integration into existing COBOL applications. No external services or specialized hardware are required.

The primary function is to encrypt and decrypt data using the AES algorithm. This protects sensitive data at rest and in transit within COBOL environments.

The Redvers Encryption Device exposes its functionality through two COBOL subroutines: RCENCRYP and RCDECRYP. These subroutines are called directly from COBOL programs.

The syntax for RCENCRYP is CALL 'RCENCRYP' USING INPUT-DATA, OUTPUT-DATA, KEY. The syntax for RCDECRYP is CALL 'RCDECRYP' USING INPUT-DATA, OUTPUT-DATA, KEY.

The device operates directly within the COBOL application's memory space. There are no external communication protocols or ports involved.

The Redvers Encryption Device protects sensitive data processed by COBOL applications, ensuring compliance with data security regulations. It minimizes the risk of data breaches and unauthorized access.

By providing COBOL source code, the device allows organizations to maintain control over their encryption processes and customize the implementation to meet specific requirements.

The Redvers Encryption Device utilizes the AES encryption algorithm, a widely recognized and robust encryption standard. The key length is configurable within the COBOL source code.

The device relies on the security mechanisms provided by the underlying z/OS, z/VM, or zVSE/VSEn operating system. It does not implement its own authentication or access control mechanisms.

Audit logging capabilities depend on the logging facilities provided by the COBOL application and the underlying operating system. The Redvers Encryption Device itself does not generate specific audit logs.

The Redvers Encryption Device is deployed by including the RCENCRYP and RCDECRYP COBOL source code into the application's build process. No separate installation is required.

Configuration parameters, such as the AES key length, are modified directly within the COBOL source code. Recompilation is required after making changes.

Monitoring and logging depend on the capabilities of the COBOL application and the underlying operating system. The Redvers Encryption Device itself does not provide specific monitoring or logging features.
