• Key Concepts: 
  Attribute Value Hash (AVH) is a feature of SAP Identity Management (IDM) that allows for the secure storage of user attributes. It is a cryptographic hash function that takes an attribute value as input and produces a unique, fixed-length output. This output is used to store the attribute value in a secure manner, making it difficult for attackers to access the original value. 
  
  How to use it: 
  In order to use AVH, an administrator must first configure the IDM system to use AVH. This involves setting up the cryptographic hash function and specifying which attributes should be hashed. Once this is done, the administrator can then enable AVH for each user in the system. This will cause the specified attributes to be hashed when they are stored in the IDM database. 
  
  Tips & Tricks: 
  When configuring AVH, it is important to ensure that only those attributes that need to be secured are hashed. Hashing too many attributes can lead to performance issues and can also make it difficult for users to access their own data. Additionally, it is important to ensure that the cryptographic hash function used is secure and up-to-date.
