Any data transmitted online remains vulnerable to unauthorized interception or even download. This can include personal or sensitive data like passwords, credit card numbers, and bank account details. So, finding an effective way to protect this information is essential.
In addition, a hacker may retrieve your past conversations upon getting hold of your private keys. Perfect forward secrecy (PFS) is one of the best ways to prevent this from happening and keep you safe online.
What is Perfect forward secrecy?
Perfect forward secrecy (PFS) is an encryption type that regularly changes the encryption key to protect your online activities. So, only a tiny bit of your data will be compromised in case of a security breach.
It is designed to switch keys after every call, message, and web page load. As a result, the intruder will only manage to get one message or operation because the rest of the data is encrypted with different keys.
The system will also safeguard the data of networks using the SSL/TLS protocols if their assigned keys are compromised.
