Re: Oracle Application Express / Password hashes

Passwords are stored as salted MD5 values according to 
programming4.us/database/8126.aspx

What you need after extracting the hash values is to use a password 
cracker that handles Oracle specific salted MD5. Both John the Ripper & 
Hashcat can do that:

www.hashcat.net
www.openwall.com/john/

Both have forums where you can ask for help. There are also commercial 
services on top of these freeeware tools to help you out, eventually to 
speed up the process.

Best regards,
