• Key Concepts: 
  Public-key cryptosystem is a type of encryption technology used in SAP BC-SEC Security. It uses two different keys, a public key and a private key, to encrypt and decrypt data. The public key is used to encrypt data, while the private key is used to decrypt it. This ensures that only the intended recipient can access the data. 
  
  How to use it: 
  In order to use public-key cryptosystem, users must first generate a pair of keys. The public key is then shared with the intended recipient, while the private key is kept secret. When sending data, the sender will use the recipient's public key to encrypt the data. The recipient will then use their private key to decrypt the data. 
  
  Tips & Tricks: 
  It is important to keep your private key secure and not share it with anyone else. If someone else were to gain access to your private key, they would be able to decrypt any data encrypted with your public key. Additionally, it is important to regularly update your keys in order to ensure that your data remains secure.
