+How to create CADI Keyfile & Encrypt Password
+---------------------------------------------
+
+Password Encryption
+-------------------
+CADI provides a method to encrypt data so that Passwords and other sensitive data can be stored safely.
+
+Keygen (Generate local Symmetrical Key)
+A Keyfile is created by Cadi Utility.
+
+.. code:: bash
+
+  java -jar cadi-core-<version>.jar keygen <keyfile>
+Given this key file unlocks any passwords created, it should be stored in your configuration directory and protected with appropriate access permissions. For instance, if your container is Tomcat, and runs with a "tomcat" id, then you should:
+
+.. code:: bash
+
+  java -jar cadi-core-<version>.jar keygen keyfile
+  chmod 400 keyfile
+  chown tomcat:tomcat keyfile
+  
+Digest - Encrypt a Password
+---------------------------
+The password is obtained by using the Cadi digest Utility (contained in the cadi-core-<version>.jar).
+
+.. code:: bash
+
+  java -jar cadi-core-<version>.jar digest <your_password> <keyfile>
+   •	"<keyfile>" is created by Cadi Utility, #keygen
+   •	Understand that if you change the keyfile, then you need to rerun "digest" on passwords used in the users/groups definitions.
+   •	Note: You cannot mix versions of cadi; the version used to digest your password must be the same version used at runtime.
+   
+CADI PROPERTIES
+   CADI properties, typically named "cadi.properties", must have passwords encrypted.
+      1.	Take the results of the "Digest" command and prepend "enc:"
+      2.	Use this as the value of your property
+	  
+Example:   aaf_password=enc:fMKMBfKHlRWL68cxD5XSIWNKRNYi5dih2LEHRFMIsut
