Before changing any certificate
settings, you must make sure that
you really trust the owner of the
certificate and that the certificate
really belongs to the listed owner.

Digital signature

You can make digital signatures with
your phone. This feature requires
support from your SIM card. The
signature can be traced back to you
via the private key on the security
module and the user certificate that
was used to perform the signature.
Using the digital signature can be
the same as signing your name to a
paper bill, contract or other
document.
To make a digital signature, select a
link on a page, for example, the title
of the book you want to buy and its
price. The text to sign (possibly
including amount, date, etc.) will be
shown.
Check that the header text is
and that the digital signature icon
is shown.
Note: If the digital signature
icon does not appear, there
is a security breach, and you
should not enter any
personal data such as your
signing PIN.
To sign the text, read all of the text
first and then you can select Sign.
