VPN encryption

VPN Encryption: Keeping Your Online Activity Safe and Secure



If you want to protect your online data from prying eyes, using a virtual private network (VPN) is a great place to start. VPNs offer an added layer of security by encrypting your internet connection and routing your traffic through remote servers. This means that even if someone manages to intercept your data, they won't be able to make heads or tails of it without the encryption key.
But not all VPNs are created equal when it comes to encryption. Here are the two most common encryption protocols used by VPNs today:
1. AES-256: This is the gold standard of encryption protocols. AES stands for Advanced Encryption Standard, and 256 refers to the number of bits used in the encryption key. AES-256 is virtually unbreakable with current technology, making it the go-to choice for most VPNs.
2. OpenVPN: OpenVPN is an open-source encryption protocol that uses OpenSSL and UDP/TCP protocols to secure your connection. It also allows for more advanced configurations, such as the ability to specify the encryption cipher and key size.
It's worth noting that not all VPNs use these encryption protocols exclusively. Some may use weaker encryption protocols, such as PPTP or L2TP/IPsec, which are more vulnerable to attacks. Always do your research before choosing a VPN provider to ensure that they use the highest level of encryption available.
The bottom line is that VPN encryption is essential for keeping your online activity safe and secure. By using a VPN with strong encryption protocols, you can rest assured that your data is protected from hackers, spies, and other prying eyes.

Router NAT traversal

Router NAT traversal


Do you ever feel like your router is out to get you? NAT traversal is one of those things that might make you want to pull your hair out if you're not familiar with it. But fear not, we're here to break it down for you.
NAT stands for Network Address Translation, and it's a feature on your router that allows multiple devices on your local network to share a single public IP address. This is great for conserving IP addresses, but it can create problems when you're trying to connect to devices from outside your local network.
That's where NAT traversal comes in. It's a technique for getting around the NAT barrier and establishing connections with devices on the other side. There are a few different methods for NAT traversal, including:
1. Port forwarding: This involves manually specifying which ports on your router should be opened up and forwarded to specific devices on your local network.
2. UPnP: Universal Plug and Play is a protocol that allows devices to automatically configure port forwarding rules on your router.
3. NAT-PMP: A similar protocol to UPnP that's used by Macs and other Apple devices.
4. VPN: A Virtual Private Network can be used to establish a secure connection between devices on different networks, bypassing the need for NAT traversal.
NAT traversal can be a bit complicated, but it's an important concept to understand if you want to be able to connect to devices on your local network from outside. So take some time to learn about the different methods of NAT traversal and figure out which one works best for your setup. Your future self will thank you!
