Encrypt a JWE with a Symmetric Wrapping Key
See more JSON Web Encryption (JWE) Examples
Demonstrates Jwe.SetWrappingKey, which sets the symmetric key-wrapping key for a recipient. The key bytes are supplied in a named encoding such as hex or base64.
Background. AES key wrapping protects the content-encryption key with a shared symmetric key. Both parties must possess the same wrapping key.
