Encrypt a JWE with a Password (PBES2)

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.SetPassword, which sets the PBES2 password for a recipient. The example uses PBES2-HS256+A128KW key management with AES-128-GCM content encryption.

Background. PBES2 derives a key-wrapping key from a password using a salt and iteration count, allowing password-based JWE encryption. The password should come from a secure source.
