 - Ability to specifiy conditions: offline mode, motion region, time table, continuous recording, etc.

+## Encryption
+
+You can encrypt your recordings and outgoing MQTT messages with your own AES and RSA keys by enabling the encryption settings. Once enabled all your recordings will be encrypted using AES-256-CBC and your symmetric key. You can either use the default `openssl` toolchain to decrypt the recordings with your AES key, as following:
+
+    openssl aes-256-cbc -d -md md5 -in encrypted.mp4 -out decrypted.mp4 -k your-key-96ab185xxxxxxxcxxxxxxxx6a59c62e8
+
+, and additionally you can decrypt a folder of recordings, using the Kerberos Agent binary as following:
+
+    go run main.go -action decrypt ./data/recordings your-key-96ab185xxxxxxxcxxxxxxxx6a59c62e8
+
+or for a single file:
+
+    go run main.go -action decrypt ./data/recordings/video.mp4 your-key-96ab185xxxxxxxcxxxxxxxx6a59c62e8
