+### Encrypted Files
+
+To examine an encrypted rfile the necessary encryption properties must be
provided to the utility. To do this
+the `accumulo.properties` file can be copied, the necessary encryption
parameters added, and then the properties file can
+be passed to the utility with the `-p` argument.
+
+For example, if using `PerTableCryptoFactory` and the `AESCryptoService`, you
would need the following properties in
+your accumulo.properties file:
+
+ general.custom.crypto.key.uri=<path-to-key>/data-encryption.key
+
instance.crypto.opts.factory=org.apache.accumulo.core.spi.crypto.PerTableCryptoServiceFactory
+
table.crypto.opts.service=org.apache.accumulo.core.spi.crypto.AESCryptoService
+
+Example output:
+
+ $ accumulo rfile-info /accumulo/tables/1/default_tablet/A0000004.rf -p
<path-to-properties>/accumulo.properties

Review Comment:
Good point, I will get rid of that as it is too verbose and there's also
already a full example of output earlier.
