Because CAcert is a certificate authority (CA) people rely on us knowing about the identity of the users of our certificates. So even as we value privacy very much, we need to collect at least some basic information about our members. This is especially the case for everybody who wants to take part in our web of trust.Your private information will be used for internal procedures only and will not be shared with third parties.
A proper password wouldn't match your name or email at all, it contains at least 1 lower case letter, 1 upper case letter, a number, white space and a misc symbol. You get additional security for being over 15 characters and a second additional point for having it over 30. The system starts reducing security if you include any section of your name, or password or email address or if it matches a word from the english dictionary...
Note: White spaces at the beginning and end of a password will be removed.
