      • encrypt

        @Deprecated
        public JWECryptoParts encrypt​(JWEHeader header,
                                      byte[] clearText)
                               throws JOSEException
        Deprecated.
        Encrypts the specified clear text of a JWE object.
        Parameters:
        header - The JSON Web Encryption (JWE) header. Must specify a supported JWE algorithm and method. Must not be null.
        clearText - The clear text to encrypt. Must not be null.
        Returns:
        The resulting JWE crypto parts.
        Throws:
        JOSEException - If the JWE algorithm or method is not supported or if encryption failed for some other internal reason.
