Privacy is one of the key issues of the information age. Especially in the post-Snowden era this fact has become clear to most individuals around the globe. Especially journalists seek for an opportunity to keep the sensitive result of their work hidden. This fact was recently underlined by an open letter from 150 journalists to camera manufacturers, demanding built-in encryption for DSLR-cameras. In the course of our research we found that an universal approach using SD-cards for direct encryption satisfies the journalist's requirements manufacturer-independent. We used libsodium on a modified WiFi-capable SD-card.
