One of our clients have requested these features for the business process management system he is going to chose:-

1. Not to use open source databases. But currently in joget the processes information, users info , organization information,etc are being stored on the mysql server.
2. Online user registration. But currently Joget only support manually creating new users.
3. specifying user's password format. For example to be minimum of 8 digits and to be a combination of both upper and lower cases, etc.
4. How to implement digital signatures that mimic manual signatures if certain workflow activities are critical. such activities include; financial approvals by the financial managers,  formal, employment approval, etc.

Can anyone help me in figuring out how i can implement such features on my current Joget version3 which will include:-

1. use oracle DB instead of Mysql to store processes, users, organization , etc information

2. implement user registration screen.

3. forcing specific users password format for the online user registration.

4. adding digital signature at certain activities
