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.

    header.UpdateString("alg","PBES2-HS256+A128KW");
    header.UpdateString("enc","A128GCM");

        std::cout << jwe.lastErrorText() << "\r\n";

    //  Set the PBES2 password for recipient 0.  The password should come from a secure source rather than
    //  being hard-coded.
