4/19/2024 0 Comments Ps2 roadblock game![]() ![]() I'll admit this is a pretty unlikely case since releasing the key is a stupid move after someone has stolen it. Usually, this key won't be publicly released and I can't think of any time they have been if it ever happens that one is publicly released that belongs to a CA the PS2 trusts, and the PS2 doesn't do revocation checking then you could use that key to generate an acceptable certificate for DNAS. Occasionally some random CA will have their key stolen. I don't remember if the PS2 does revocation checking but while writing I had the thought of using a stolen CA key. If someone wants to take up this challenge there are a few possibilities: Why waste time building a DNAS clone when it can't be used unless you already skip DNAS? The three classic methods of dealing with this are to either add your own CA to the trusted list of CAs, or to change the domain it tries to contact to one you can get a certificate for, or disable certificate verification.Īll of those are applicable on the PS2, however if you have access to do any of these on your console, you'd also have access to simply disable DNAS altogether by patching it out. Preventing someone from masquerading as another server is one of the primary purposes of using SSL/TLS in the first place, so it is not surprising that this is a major roadblock. You can create your own CA and sign a certificate (called self-signing) but that CA won't be trusted by the PS2.Īll this to say when the PS2 attempts to connect to the DNAS server If the signature doesn't match the content, or if the CA's signature is not from a trusted source, or a number of other reasons the certificate is rejected and the connection won't go forward. Part of the verification of a certificate the PS2 receives when connecting to DNAS is to check for this CA's signature and that the CA is one that the PS2 trusts. Once they are satisfied they sign your certificate. When you request a CA sign your certificate they will verify certain aspects of the certificate, at the cheapest level they just verify you control the domain name the certificate is for and more expensive ones will verify the company and personal information also. Not only does the private key sign it but you need to get this certificate signed by a 'Certificate Authority' (CA for short). So one question someone might then ask is: What is stopping me from creating a certificate with my own keys and just saying it's from Sony, this is prevented by a sort of 'chain' of signatures. If you change any details in the certificate(like the domain name) then verification will fail unless you update the signature using the private key.so basically this prevents tampering of the certificate. This signature can be verified using the public key but can only be generated using the private key. This certificate is then 'signed' using the private key. ![]() There is a certificate that is provided when you connect to the server and try to establish a secure connection, this certificate includes stuff like who you're connecting to (the domain name, company name, etc) and it includes the key you can use to encrypt a message to the server(there is a separate key for decryption only the server knows). SSL/TLS (the protocol that provides encryption for TCP connections, DNAS is over TCP) is based on public key cryptography. I figured I'd add an explanation of the problem for anyone who wants to try and pick up where I left off: It cannot be reverse engineered and even with modern computing it is still not feasible to generate the private key from the public key. Using that would be illegal unless we reverse engineered it which is pretty much cracking it.įor what its worth, using the key wouldn't actually be illegal, the illegal thing would (likely) be getting access to that key since SSL/TLS is built on public key cryptography, the private key never leaves the server. ![]() On the following page, explain why the content you’re reporting is inappropriate for Roblox.The main issue is that sony own the key to their SSL connection. Step 5 – From the main page on Roblox, hover over the game or experience you want to report. Step 4 – On the friend’s profile, select Report Abuse and then fill in information about why you’re reporting the user. ![]() Step 3 – From the main page on Roblox, click on the friend’s profile image and select View Profile. Fill in the information for why the user needs to be reported. Step 2 – Find the user that you want to report and click the flag next to their name. This will show a list of all users in the current game or lobby under People. Step 1 – While playing, select the Roblox icon in the top left corner. Show children how and when to use these functions on the platform. To keep Roblox safe for all users, it’s important that your child knows the importance of reporting and blocking users or content that is inappropriate.
