EncryptionKey class abstract final Database Enterprise Edition
A key used to encrypt a Database.
This feature is only available in the Enterprise Edition.
This is an AES-256 key, which is 32 bytes long.
A key can be created from the raw bytes through key. It is important to use a cryptographically secure source of randomness to generate this key, for example Random.secure.
Alternatively a key can be derived from a password through passwordAsync or passwordAsync. If your UI uses passwords, call one of these method to create the key used to encrypt the database. They are designed for security, and deliberately run slowly to make brute-force attacks impractical.
