So you need to make sure you find out which level of encryption the website you are visiting uses, to make sure they are using at a minimum 2,048, if not 4,096 bits. Unfortunately, many websites today are still using private keys that are only 1,024 bits long which in today's world are no longer enough. A public key is provided to those who want to send an encrypted message and the only one who can decrypt is the one with the private key. When you visit a website using HTTPS, you are encrypting your request using their public key and they are decrypting it using their private key.

You must be made aware however, that HTTPS can also be currently cracked depending on the level of the key used to encrypt it. This is particularly easier when you are sending requests in plain text, but HTTPS reduces this possibility. If somebody were to intercept your request over HTTP Secure, they would see encrypted data and would have to work to decrypt it.Īnother reason you want to use HTTPS whenever possible, is that malicious Tor nodes can damage or alter the contents passing through them in an insecure fashion and inject malware into the connection. This is another form of endtoend encryption. What this does is encrypts your requests so that only the server can decrypt them, and not somebody eavesdropping on your communication such as a compromised Tor exit node. If you see hxxps:// then your website is using HTTP Secure. You can tell if the website you are visiting is using HTTP Secure by the prefix at the beginning of the address. If you are putting a credit card, a bank account, your real name, even your login information, then you are compromising your identity.Īnother step you can take, is to only visit websites that use something called HTTP Secure. So if you are entering your name and address into a field, the exit node has your information. The exit node can see what you are sending in clear text once they decrypt it. Remember, the exit node has the key to decrypt your request. The web server of the hidden service now becomes your exit node, which means the website you are visiting is the one decrypting your message, not some random exit node ran by a potential attacker. What this does is take the power out of the compromised exit nodes and put them back in your hands. These services offer what's called endtoend encryption. You can easily recognize these services by the address. So what can we do to fix this? Well, luckily we are now having more and more servers that are offering something called Hidden services. If any of the nodes in the chain are compromised, and some likely are, and the people in charge of those compromised nodes have the computing power to decrypt your request, then you better hope it wasn't anything sensitive. You should not be entering any sensitive data into any websites, especially when accessing them over TOR. The FBI can set up an exit node, the NSA, or any other foreign government, or any malicious person who may want to steal your information. The problem comes obviously when you are entering plain text into TOR because anybody can set up an exit node. Using this model of 3 nodes it makes it harder, but not impossible to correlate your request to your original IP address. The exit node does not know your computer's IP, only the IP of the relay node. The exit node, is where your request is decrypted and sent to the internet.
The relay node communicates with the entry node and the exit node but does not know your computer's IP address. The entry node then passes your encrypted request onto the relay node. This entry node communicates with your computer, this entry node knows your IP address. This is why, you should never send anything over Tor that you aren't comfortable sharing with the entire world unless you are using some sort of PGP encryption which we will talk about later.Ĭommunication from your computer, to the internet relies on an entry node which basically "enters your computer" into the Tor network.

There has been some debate as to whether or not the NSA can crack this code, and the answer is likely yes. Tor will provide you with a degree of anonymity by using an 128bit AES (Advanced Encryption Standard). If this is the case, then the #1 thing you must be using to even access this form is Tor. I would like to start out by saying, if you are reading like, you are likely a Silk Road user. But if I can help anyone out, then I am grateful for this. The reason I put this together is mainly for the newbies of this forum. Through my research I have put together some security measures that should be considered by everyone.
