 However, since Rails 4, the default store is EncryptedCookieStore. With EncryptedCookieStore the session is encrypted before being stored in a cookie. This prevents the user access to the content of the cookie and prevents him from tampering its content as well. Thus the session becomes a more secure place to store data. The encryption is done using a server-side secret key `secrets.secret_key_base` stored in `config/secrets.yml`.
 
-That means the security of this storage depends on this secret (and on the digest algorithm, which defaults to SHA1, for compatibility). So _don't use a trivial secret, i.e. a word from a dictionary, or one which is shorter than 30 characters, use `rake secrets` instead_.

 `secrets.secret_key_base` is used for specifying a key which allows sessions for the application to be verified against a known secure key to prevent tampering. Applications get `secrets.secret_key_base` initialized to a random key present in `config/secrets.yml`, e.g.:
