When using encryption, the expected value (once encrypted) would never be the same as the encrypted value in the storage layer. As a result, it would never be possible to putC or delC a KV item. Now the mysql package first gets the key from the storage layer, and then checks it’s decrypted value, before attempting to overwirte the value in the storage layer.
