/* password checking routines */
/*****************************************************************************
The main idea is that no password are sent between client & server on
connection and that no password are saved in mysql in a decodable form.
On connection a random string is generated and sent to the client.
The client generates a new string with a random generator inited with
the hash values from the password and the sent string.
This 'check' string is sent to the server where it is compared with
a string generated from the stored hash_value of the password and the
random string.
The password is saved (in user.password) by using the PASSWORD() function in
mysql.
Example:
update user set password=PASSWORD("hello") where user="test"
This saves a hashed number as a string in the password field.
