Options
| Option | Default | Meaning |
|---|---|---|
keyProvider | — | Returns the symmetric key or RSA key pair. Sync or async. |
customHandlers | — | Your own encrypt/decrypt for method: "Custom". |
failClosed | true | Throw when encryption fails rather than sending plaintext. |
failClosed defaults to true on purpose: a middleware that silently falls back
to plaintext when a key is missing is a middleware that will one day ship an SSN
in the clear.
