A bank key is a distinctive, nation-specific identification. It serves as a bank’s exclusive internal SAP ID. This ID ties to the other bank information in the system, such as name, bank number, and SWIFT code or BIC, along with the country key.

A bank key is used to identify your bank in a certain nation specifically. It is the account number and complete address information for the bank account. In other words, the bank key serves as the bank branch’s identification, and each bank key designates a specific bank branch.

Each country has a unique bank key that is peculiar to that nation. It is possible to configure the bank key to match the bank number for your country key of type 1 or to match the SWIFT code for international countries to make the data more accessible and visible key of type 4.

The key will follow the same formatting guidelines as any other bank number if the bank key is configured to match the bank number. The key’s length can only be 11 alphanumerical letters if the bank key is configured to match the SWIFT code.

If you are still determining exactly how long a country’s bank number should be, you can enter a maximum of 15 letters and then restrict it once you know.

10 Steps of a Bank Key Identification Process

Key Management System

Most security measures used by Internet banking applications rely on cryptography, which also requires secret keys. A key management system security policy should be established to make it simple for the individuals in charge of maintaining the policy to comprehend it and effectively carry out their respective tasks and duties.

Malware Protection

The information should be scanned for malware by key management system devices or servers that receive communication data, files, and other information across unprotected networks. If no data is sent across insecure networks or if all data is strongly encrypted, malware protection might not be as important.

Server and Device Hardening Documentation

Hardening is the process of removing an attack vector by fixing holes and shutting down non-essential services. A breach in the network security measures protecting the key management system could lead to a breach in the management system of the key itself.


An expert can employ effective shortcuts and ignore step-by-step instructions, while a novice or less experienced user can be guided via user interfaces that adapt to their knowledge.

Third-Party Testing

It evaluates a key management system device for compliance with a certain standard through independent testing. Third-party testing assures the vendor that it did not miss a fault in its testing processes.

Remote Watching

A key management system should audit security-relevant events by detecting and documenting the event, the date and time, and the identity or role of the entity starting the event.

Establishing the Proper Crypto-Periods for Keys

The crypto period of a key is typically understood to represent the time interval between activation and deactivation. According to the key management system security policy, this time often has a maximum value dependent on the sensitivity levels of the data it is safeguarding.

Defining the roles and responsibilities of the Key Management System

Key management system solutions are in place in banking businesses, but some must properly delegate roles and duties. The people executing each role should have access to the key and metadata management functions required to fulfill the role’s duties. Each role should have specific authorizations configured for it.

Observing the organization’s information security guidelines

Different policies for various uses or kinds of information may exist inside an organization. Key management system security policies must be established based on the bank’s information security policy. The use and security of cryptographic keys, algorithms, and metadata are included here.

Cryptographic Zones: Definition and Classification

Account numbers, PINs, passwords, and transaction details are sensitive data used in banking apps. Both in transit and at rest, these data are encrypted. The asymmetric or asymmetric public key is shared between two sites in a cryptographic zone to encrypt sensitive data. In some situations, data is encrypted within this zone once the key or keys have been exchanged, and others keys.
