Change the behavior when the encryption is not possible

The encryption library use the browser native WebCrypto library to work (or NodeJS Crypto library on a server).

But there is case where the WebCrypto library may not be available, for example on a not secure URL.

By default, this library will raise an exception.

But you can change this with this code:

import { noEncryptionBehavior, NO_ENCRYPTION_BEHAVIOR } from "@macfja/svelte-persistent-store"
noEncryptionBehavior(NO_ENCRYPTION_BEHAVIOR.NO_ENCRYPTION)

Put this function call before calling the persistent storage or in the init/boot script.

List of behavior

Name	Numeric value	Comment
[[NO_ENCRYPTION_BEHAVIOR.EXCEPTION]]	0	(default) Raise an exception
[[NO_ENCRYPTION_BEHAVIOR.NO_ENCRYPTION]]	1	Use the wrapped Storage as-is. Data will be saved not encrypted
[[NO_ENCRYPTION_BEHAVIOR.NO_STORAGE]]	2	Don't use any storage, so no not encrypted data will be persisted
