Forgive me for this being slightly off topic.  We've checked Oracle's

missing something? ... Or should something this obvious be available on
Oracle's site? Can anyone provide links to such information?

Hash: SHA1

I've put together a tool that can be used to build a table of Oracle
password hashes from a dictionary file for a designated username.
Hashes are calculated by creating a user account similar to the target
account to be audited and repeatedly changing the password with "ALTER
USER" for each dictionary word, storing the hash for each password in a
table.

Once the table of hashes is built, a simple SELECT can be issued to
determine if the password hash for a target user is a simple dictionary
word:

SQL> select h.username, h.password, h.hash
 2  from hashattack h, dba_users d
 3  where d.password = h.hash and h.username = 'SYS';

USERNAME   PASSWORD             HASH
- ---------- -------------------- --------------------
SYS        KILTPLEAT            2BBDC477FFB28563
