I want to buy a product on line and the company has
requested from me to send an e-mail message with my
personal details, which include my credit card number and
security code. This is apart from the normal registration
procedures. Now, I am worried about sending my card
detailes on an ordinary e-mail. Can I encrypt it? How do I
do that?

All this is very urgent since all I want to buy is food in
a supermarket in Argentina -from England- for my mother
who is a pensioner, and acually is not being able to buy
thw essentials because of the finanacial crisis in my
country.

I'll appreciate solidary help in this matter, but since I
do not understand IT jargon, it will have to be in plain
English.

Cheers,

Rossana
