Encryption helps with what?
Bayanin Amsa
Encryption helps with safe delivery of messages to their destination without being accessed by a third party. Encryption is a process of converting plain text into coded or scrambled text so that only authorized parties who have the key can access and understand the original message. This means that even if an unauthorized person intercepts the message during transit, they cannot read or understand it because it is encrypted. Encryption is commonly used to protect sensitive data such as passwords, credit card numbers, and personal information when it is transmitted over the internet. It also helps to protect confidential business or government communications from hackers, cybercriminals, and other unauthorized third parties. Therefore, encryption helps to ensure that messages are delivered safely and securely to their intended recipients without being accessed or intercepted by unauthorized parties.
