Ext.Direct form submit password encoding

Hello,

I am using Ext.Direct form Submit for my "change password" formPanel and I noticed my variables were passed in the POST as they were typed in the form. I would like to encrypt the formValues with MD5 but I can't seem to find the way to do so.

Here is the post content :

Code:

---

current_password        a12345
extAction        WS_User
extMethod        changeUserPassword
extTID        3
extType        rpc
extUpload        false
new_password        a123456
repeat_password        a123456

---

Anybody could help? Thanks!
