The moment unwrapped, the message would only make sense if the receiver had the right span of rod. Modern cryptography draws on mathematical designs that scramble data therefore it can only be decrypted by the intended receiver using the right key.
There are many types of encryption, nevertheless the most common is symmetric cryptography, which uses precisely the same key to the two encrypt and decrypt info. For example , you can use a electronic private network (VPN) that encrypts the details you publish on your computer to patrol your privateness online. You can also encrypt board computer protection software emails and phone calls to make certain no one can intercept your discussions.
