JweDirectSerializer

public JweDirectSerializer(Serdes serdes,
                           java.util.Base64.Encoder encoder,

Method Detail

JWEToCompact

public java.io.ByteArrayOutputStream JWEToCompact(JWE jwe)
                                           throws JsonToJwtException,
                                                  CipherException,
                                                  EncryptException

Generates a compact JWE. Ignores the value for the jwe iv and generates a new one. The variable symmetricCipher is a propagating dependency. It cannot be reused per encryption attempt because it requires a new iv and aad per attempt.

Specified by:

JWEToCompact in interface JweSerializer

Parameters:

jwe - must have values for header, cek, payload. Ignores the value for iv and generates a new one.

Returns:

a ByteArrayOutputStream that is a compact JWE

Throws:

JsonToJwtException - if the header cannot be serialized.

CipherException - if the cipher for encryption could not be instantiated

EncryptException - if the payload could not be encrypted
