Replaces cleartext passwords in the database with a secure hash
===============================================================
For your existing user base, the removal of the cleartext
passwords occurs immediately when you instal base_crypt.

All passwords will be replaced by a secure, salted, cryptographic
hash, preventing anyone from reading the original password in
the database.

After installing this module it won't be possible to recover a
forgotten password for your users, the only solution is for an
admin to set a new password.

Security Warning
++++++++++++++++
Installing this module does not mean you can ignore other security measures,
as the password is still transmitted unencrypted on the network, unless you
are using a secure protocol such as XML-RPCS or HTTPS.
It also does not protect the rest of the content of the database, which may
contain critical data. Appropriate security measures need to be implemented
by the system administrator in all areas, such as: protection of database
backups, system files, remote shell access, physical server access, etc.

Interation with LDAP authentication
+++++++++++++++++++++++++++++++++++
This module is currently not compatible with the ``user_ldap`` module and
will disable LDAP authentication completely if installed at the same time.
