title: Oracle XE and DBMS_CRYPTO
body: <p>is there no DBMS_CRYPTO package on Oracle XE databases?
  I searched the SYS user packages and all I could find was a DBMS_CRYPTO_TOOLKIT</p>
  
  <p>When I try to grant execute on DBMS_CRYPTO I get an error that the Table or View was not found. 
  Is it stored anywhere else?</p>
  
  <p>I hope you can help me :) THX</p>
