Adding keys of type SECMSG, which are used to encrypt PINs and secure messages, typically involves accessing a Key Generation and Update Program (KGUP) or a similar system designed for managing cryptographic keys. Within the KGUP program, the process generally entails generating a new key using the DES algorithm and specifying parameters such as key type, expiration date, and usage restrictions. Once the key is created, it needs to be securely distributed to the systems or devices that will utilize it for encryption.

This distribution should be conducted in accordance with established key management practices to safeguard the key's integrity throughout its lifecycle. If the key is intended for use with a specific service like CSNBSK, integration and configuration with the service should be performed following the relevant specifications and requirements. It's essential to adhere to any documentation, guidelines, or regulatory standards governing cryptographic key usage and security practices throughout the entire process.
