What is Encryption?
Encryption prevents unauthorised access to your data, by keeping communication secure between the parties involved.
Data sent from one person to another is scrambled into a code meaning it’s unreadable for anyone except the sender and recipient to read. Only the users involved have access to modify the data to make it readable and then readable again.
What this means is that data received or intercepted by the wrong person will make no sense as they do not have the key to decrypt it.
If implemented properly end to end encrypted data could takes years and years for Cybercriminals to hack into as it uses complex mathematical algorithms and numerical sequences.
A recent article in The Telegraph talks more about why encryption is controversial. http://bit.ly/2okyONT
