WebMay 21, 2024 · There are even modes, such as Counter (CTR), that can turn a block cipher into a stream cipher. In contrast to symmetric ciphers, there are asymmetric ciphers (also called public-key cryptography). These ciphers use two keys: a public key and a private key. The keys are mathematically related but still distinct. WebApr 11, 2024 · At the most basic level, the data on disk is encrypted with an Azure internal key referred to as the Data Encryption Key (DEK). For a given cluster, a customer-managed key, called the Key Encryption Key (KEK), is used to encrypt the service’s DEK.
