| Re: [Vonage] SIP credentials, RTP300, GPP_K? Excellent explination. Thanks.
Any ideas how it is encrypted and how to decrypt it? As shown above, I do have the passphrase. Everything rcilink I have been able to duplicate just as described. Now the decrypting of the XML file is all that is left. | |

| Re: [Vonage] SIP credentials, RTP300, GPP_K? Perhaps the file is encrypted using a different encryption scheme. When you execute the command:
quote:
openssl aes-256-cbc -d -in ti00xxxxxxxxxx.xml -out cleartext.xml -k AB82DD541xxxxxxxxxxAA622E9FC6F43EAE48FDF93D1F4E789DFA93005C2D8AA
"aes-256-cbc" is the encryption scheme you're instructing openssl to use. openssl supports numerous encryption schemes (google the openssl docs), so perhaps try some other schemes. Try writing a script / batch file to go through all possible schemes offered by openssl.

| Re: [Vonage] SIP credentials, RTP300, GPP_K? said by rizzo2dial  :Try writing a script / batch file to go through all possible schemes offered by openssl. Rizzo That is what I did in the post about 4 messages up. I got the same error. I'll try to attach the file.
One thing I did last night was to use the same hack from rcilink, look at my values, make changes in the screen and click save. It worked! After reloading my page, even unplugging the router and relogging back in, my chages were there. I then went to all the screens that are in the voice folder and used the same delay/esc trick to get copies of all the files in there so I can change the routers settings. The user screen, provisioning and everything can be changed. Just one screen voiceAuthenticate.html is a problem. This screen is where you can change the "Admin" (big admin). It will let me change but when I save it an error about being outside the html path occurs.
The good thing is I can make changes. I'm going to print the screens of all the voice pages and fill in what I need from my working PAP2 so I can insert all the correct info. We'll see if this will work.
One other thing I tried is in the Provision.html, I removed my encryption key, which worked, but then I tried to give it an unencrypted file. For some reason my tftp server would send but time out sending it. It seems the rtp300 will ask but not transfer it.
I also found this:
»www.profiber.dk/media/router_opdatering.pdf
This talks about an rtp300 with firmware 3.1.10 including screen shots of the voice screens. Anyone seen this? I tried to get the .bin file but no luck. The IP in the example and the IP of the host of the file come from the same place. That is as far as I got. Anyone have a rtp300-na? What is the firmware version for that model? | |

@rr.com | Re: [Vonage] SIP credentials, RTP300, GPP_K? I'm quite sure the algorithm is rc4 and it is a raw key. I'm not sure if the whole string is the key or if there is an initialization vector. | |

@rr.com | Re: [Vonage] SIP credentials, RTP300, GPP_K? Oh, I can't test it, but rc4 is a stream cypher so you can use the same program to reencrypt it with the same key, then you should be able to feed it to the router. | |

|  RC4.zip 22,381 bytes
rc4 Windows Executable + Source Code |
Attached is a zip file containing the modified source code as well as a Windows (DOS/Command Prompt) executable. Since it's compiled under VS.NET 2003 (which is a development environment for the .NET 1.1 framework), the Microsoft .NET 1.1 framework will likely need to be installed for the program to run. (Microsoft provides it for free).
The syntax for this version is of rc4 is:
rc4 key inFile outFile

| Re: [Vonage] SIP credentials, RTP300, GPP_K? The: rc4 key inFile outFile, and question is what is the "infile" and what is the "outfile" is supposed to be called?
I just want to unlock my rtp300 so I can firmware upgrade, cause these bastards locked it all up.
So can you explain a bit more?

I hope you will, or someone will reply.
Uuummm... My friend just told me you guys might not answer cause vonage put you all in jail?
If you want me to slap my friend sebastian again, I will be glad too... No offense, I am curious.
