title: DBMS_CRYPTO package is missing
body: <p>I am using Oracle Database 11g Enterprise Edition Release 11.2.00.40 - 64bit Production. We have a initial admin user which will be created in a database by inserting into a table during the installation. This action requires to encrypt password using SH1 protocol. Acording to Oracle documentation I should be able to use DBMS_CRYPTO package which comes with Enterprise Edition of database. However I am not able to see it. Instead of DBMS_CRYPTO I can see DBMS_CRYPTO_TOOLKIT package. This package is not so well documented but I was able to find that it comes with Oracle 12c and that even confused me more. </p>
  
  <p>Should I install DBMS_CRYPTO package aditionally or to use DBMS_CRYPTO_TOOLKIT package? Is there anybody who can explain how to encrypt pass with DBMS_CRYPTO_TOOLKIT package? I dont have SYS access to database, so I am wondering if there is a way to generate SH1 passwords without using DBMS_CRYPTO that is simple enough? In other words is it worth to install it?</p>
