WebSep 18, 2015 · A hierarchical key model is the cornerstone of Snowflake’s encryption key management. A key hierarchy has several layers of keys where each layer of keys (the parent keys) encrypts the layer below (the child keys). When a key encrypts another key, security experts refer to it as “wrapping”. WebJun 9, 2024 · A cryptographic key is a piece of data that must be managed by secure administration. It involves managing the key life cycle which is as follows: Public key management further requires: Keeping the private key secret: Only the owner of a private key is authorized to use a private key. It should thus remain out of reach of any other person.
