How to access online

I can't answer about the traffic part nor too advanced stuff, but there's one thing I know: you can't replace the certificates on the PS3. I've tried, and esc0rtd3w and kozarovv confirmed that you can't after I asked both. See this: https://www.psdevwiki.com/ps3/Online_Connections#Certificates. At the end of the table, there's this:
In latest firmwares (3.60 and later) Sony have started to hash their certificates with SHA-1 and these hashes are stored inside vsh.elf (/dev_flash/vsh/module/) and libssl.prx (/dev_flash/sys/external/)
Click to expand...
And kozarovv showed something with IDA which is they have the SHA-1 hashes, yes, but they have 2 more known ones. So to replace the certificates, you first need to know what those other 2 things mean and replace them accordingly. esc0rtd3w, I asked him about the certificates replacer for HAN, what was it made for if it seems we can't replace certificates and he said it was in case anyone figured it out or in case it might help on that. But you really can't replace them (I already tried, anyways) - unless you find out what those 2 other things are...

I'll click on Watch Thread, in case anyone gets to somewhere... Would be cool to 3 things I wanted to do and they both need me to replace at least one certificate.

EDIT: The link you have there is about FW 3.55, so what I said is supposing you're not using that old FW and yes a newer one (in this case, at minimum 4.XX).
 
Actually, now that I wrote that up there, I wonder if it wouldn't be possible to patch wherever the check for those values is on both files... Then the values would be unused at all and could even be wrong that the thing would still work. If they need to be signed by Sony for the PS3 to boot, then it would only be possible to do this on CFW, but still it would be really cool.
 
I have a crazy idea,

There is a way to bring my PS3 back to an earlier update, By doing a factory reset < Full format >!

That should restore the original firmware that came with the PS3

Do you think it will work?

no. it doesnt work like that.

if you ps3 is cfw-compatable, you can enable qa flag then install the original firmware version.
 
Hey, Now My Ps3 is cfw-compatable, firmware version is 3.55 !
Until now Charles cannot show this request auth.np.ac.playstation.net/nav/auth

Not sure what might be the problem then. Also, possibly you should create a thread with that in mind, like "How to swap PS3 CA certificates on FW 3.55?", so more people could be interested. Anyways, being you on 3.55, if you still can't replace the certificates, no idea what's the problem then.

Have you tried Google? Search something like "ps3 3.55 replace ca ssl certificates" - that got me some results but, I don't get if any of them work. But you may understand more than me about this, so that may tell you more than it told me.

EDIT: If any of those tell you something useful say here!

Also, what README.txt is that thing talking about? The CA24.cer is mentioned on one of the sites (at least one) that I found, but it has asterisks there and I can't understand the conversation. That Readme might help a bit. If you wish, can you share where you got it?
