GUIDE
AES vs ChaCha20 for VPNs
This guide explains AES and ChaCha20 in plain language. It is written to help you make an informed connection choice rather than to promise a one-size-fits-all result.
Key points
- Both are widely used modern ciphers.
- Hardware and device type can affect performance.
- Protocol implementation matters as much as a cipher label.
What to do next
Choose the option that matches your device and network, then verify the connection with the What is my IP? tool. For available connection methods, see Pow VPN downloads and setup options. You can compare plans and locations on the pricing page.
Keep the basics in mind
A VPN protects the route between your device and a VPN server. It does not replace software updates, strong passwords, careful account use or the rules that apply where you are. Test a connection on the network where you will actually use it.
