DVFieldEncryption class

How generated models reach the field cipher.

The keyring is read from the server process environment through DVSecrets and never from anything the generator writes. That is the whole point of the split: generated model code is compiled into the application bundle as well as the server, so a key that lived in generated code would ship to every visitor. Only PUBLIC_-prefixed values reach the generated environment, and a browser has no environment to read at all, so on the web this resolves to nothing and an encrypted field raises rather than storing plaintext.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Static Properties

isAvailable → bool

Whether an encrypted field can be read or written in this process.

no setter

Static Methods

configure(DVFieldCipher? cipher) → void

Supplies the cipher directly, for a host that loads keys from a manager rather than the environment, and for tests.

decrypt(String model, String field, String? value) → String?

Opens a stored value.

encrypt(String model, String field, String? value) → String?

Seals value for storage. Null passes through, so an optional column stays empty rather than holding a ciphertext of the empty string that every IS NULL query would then miss.

reset() → void

Drops a configured cipher and the parsed keyring.

Constants

secretName → const String

The environment variable holding the keyring, newest key first.
