If a signature is attached to a file, `fcrypt` automatically verifies its content whenever the file is being read.
+Note that the signed file is stored in the internal format of GPG.
+So you only see binary data when opening the signed configuration file directly.
+However, you can simply display the plain text content of the file by using GPG:
+
+ gpg2 -d signed.ecf

### GPG Configuration
The GPG Configuration is described in [crypto](../crypto/).
