[TYPO3] Encrypted FE User Password

[Justin]

Hi,

I want to encrypt the FE website users passwords.
Now If I look into the BE to the users I see the passwords, but I want to 
have encrypted password for all FE users.

I was trying to install the MD5 EXT from the TER.
But my specs are to high ( that's what the installation says.. )

I use Typo3 4.2.1.

Anybody can help me with this?
I really need this feature..

Thanks..

Justin
