I'm in doubt for using dbms_crypto on my apex application.
On premise i use
grant execute on sys.dbms_crypto to myuser;
to enable dbms_crypto.
On cloud service like https://apex.oracle.com or other oracle services dbms_crypto is enabled by default? Can i execute grant manually?
AFAIK is not possible to use dbms_crypto on apex.oracle.com. However, there is a post in oracle forums that suggests you can ask for the grant: https://community.oracle.com/message/10967002
Good luck.
