B.
Add encryptionKey on /atg/userprofiling/ProfileTools.

C.
Ensure property securityStatus of user is SECURE-SIGNin.

D.

Explanation:
To change the secret key that the Personalization module uses to hash the user ID
cookie, edit the following property of/atg/userprofiling/CookieManager:
Note: cookieHashKeySets the hash key to use for hashing user ID cookies. If this property is set,
its value is used for the hash key rather than a value generated by the HashInitializer component.
Sets a secret key that the Personalization module uses to hash the user ID cookie. This behavior

makes user cookies more secure and prevents users from using another user’s profile by
changing their cookie. Invalid profile cookies are ignored. You may want to change this from the
default value, so that your site’s cookies will be hashed with a different key from that used by other
sites that run ATG products.
