In short, it is about encrypting/encoding information transmitted from one user to another.
Encryption is the encoding of information so that it can only be read by the intended parties, i.e. the sender and recipient.
The method by which the message was encrypted is called a cipher.
Only those who know the cipher will be able to decrypt information encoded with that cipher.
Encrypting information is nothing new. In ancient Rome, Julius Caesar used a cipher to communicate. Important information to his generals bolivia phone number data without the risk of. It being read by anyone else. If someone robbed the messenger or the messenger read the message. And passed it on to someone else, battle tactics would be compromised.
Julius Caesar encryption cipher
Caesar’s cipher was quite simple and involved replacing one letter of the alphabet with another a certain number of letters away. For independent contractors example, if the decided distance was 3 letters, then D would be A, E would be B, F would be C, and so on.
Nowadays, communication often takes place over the internet.
If you use a router at home and have a password for it, the router will encrypt the connection between it and the device you are connecting to the internet from. Anyone who knows that password can also know all your online activities.
In a public place, such as a coffee shop, anyone can find out the router password and decode the messages. For this reason, encryption of dz leads information must be done at the web browser level. Any unsecured connection can be intercepted by an intermediary.
The problem with encrypting information is the decryption key. Both parties must know this key in order to communicate.
