Tools to store account (password..) in encrypted format ?

[KLEIN Stéphane <stephane@is-webdesign.com>]

Hello,



On my box, I use plain text to store my passwords but it isn't secure. 

What cli and/or web software can I use to store my password (account) in 

encrypted format ? What do you use ? 



If it's possible I would like collaborate system.



Thanks for your help.
