• Key Concepts: 
  Holder-of-key is a security concept in SAP BC-SEC Security that allows for secure communication between two parties. It is based on the principle of mutual authentication, where each party must prove its identity to the other before any data can be exchanged. The holder-of-key is the party that holds the key to the secure communication channel and is responsible for verifying the identity of the other party.
  
  How to use it: 
  In order to use holder-of-key, both parties must first agree on a shared secret key. This key is then used to encrypt and decrypt messages sent between the two parties. The holder-of-key is responsible for verifying the identity of the other party by using the shared secret key. Once both parties have been authenticated, they can securely exchange data over the secure communication channel.
  
  Tips & Tricks: 
  When using holder-of-key, it is important to ensure that the shared secret key is kept secure and not shared with anyone else. Additionally, it is important to regularly update the shared secret key in order to maintain a secure communication channel.
  
  Related Information: 
  Holder-of-key is similar to other security concepts such as public key infrastructure (PKI) and symmetric key cryptography. It can also be used in conjunction with other security measures such as digital signatures and encryption algorithms.
