Roundcube and Enigma crypt and decrypt error

Hello

Have a new problem

I generate the key, with a simple password ( 123456 ).
I test to send a mail :
I insert the password, and .... I re-type my password.. and once again... again... again..
The password does not register ...
Why? Have you had this problem?

The password is work, beacause i test with thunderbird and is work.

Please Help me.

thanks all
