Post subject: | Grooveshark Token Problems |
Hey SciLor If have spot your programm just some weeks ago. I coded a similiar one, but due to new tokens my programm doesn't work. How is the token composed now? I looked into the main.swf and tried several attempts but none of them worked. Probably you can give me some hints or solutions ![]() I could help you to put the download-routine into a (multi-)thread and include a progressbar for the downloads. PS: Kannst auch gerne auf deutsch schreiben. Ich dachte mir nur , da hier alles auch englisch ist und so ![]() |

We stay in English ![]() Where you started coding? Got some existing code?! If you have used Grooveshark Mobile Source or you working with the groovefish dll there is a simple solution: The token includes a constant string called "theColorIsRed" (I just remembered, so there may a mistake). In the version before it where "theHumansAreDead" you should replace it in your source ![]() Thank you for your "help", but I want to do it for myself, I just have no time to ^^ I want to reinvent the DLL due to some big bugs in song searching! (Good Night!) |

Do you know at what frequency they change this constant? How did you find the new constant? It appears to have changed again... I am currently working on reverse engineering their protocol for fun... communicationToken = 4ba1249e27b86 I sniffed the following packet: Code: { "header": { "token":"6b017bf5e8744f719f78c60f97dca10eaa45d742e6d502", "client":"widget", "clientRevision":"20100211.2", "session":"8f019bd4f8b4a99a116fb02a6f921637", "uuid":"64830F98-293C-97AC-69E4-6D79A5FEF785" }, "parameters": {"widgetID":20464003}, "method":"getWidgetSongListFromWidgetID" } Thus. method = getWidgetSongListFromWidgetID token = 6b017bf5e8744f719f78c60f97dca10eaa45d742e6d502 so lastRandomizer = 6b017b sha1 = f5e8744f719f78c60f97dca10eaa45d742e6d502 Unfortunately, when I compute the SHA1 myself it does not give the same result.. sha1(getWidgetSongListFromWidgetID:4ba1249e27b86:theColorIsRead:6b017b) = 16b41c5653d5dd43a7085789bca02cad2871f0e7 Any ideas? |

My mistake, theColorIsRead had a typo, it must be "theColorIsRed" The constant was changed once since the last 4 Month, so nearly never |

Wow !!! Quick reply ! :O Weird... sha1(getWidgetSongListFromWidgetID:4ba1249e27b86:theColorIsRed:6b017b) = 640f18001684848deb61ffda3e34e19c9d468eaa When it should be: sha1 = f5e8744f719f78c60f97dca10eaa45d742e6d502 |

Maybe it is because I am sniffing the Widget application and it might have a different constant? |

I create the sha in that way in c# Code: public static string GetSHA1Hash(string str) { SHA1CryptoServiceProvider sha1 = new SHA1CryptoServiceProvider(); byte[] strBytes = Encoding.ASCII.GetBytes(str); byte[] sha1Bytes = sha1.ComputeHash(strBytes); StringBuilder hashStr = new StringBuilder(); foreach (byte b in sha1Bytes) hashStr.Append(b.ToString("x2")); return hashStr.ToString(); } Just the normal creating. The token I create that way: Code: internal string GetRequestToken(string method) { string randomHex = GetRandomHexStr(); string hashStr = method + ":" + this.communicationToken + ":theColorIsRed:" + randomHex; string sha1 = HashHelper.GetSHA1Hash(hashStr); return randomHex + sha1; } As you the the random string is in front of the sha1 hash And yours seems to be different ![]() |

So strange... method = userGetPlaylists randomHexStr = cf2120 communicationToken = 4ba12d2944e1c sha1(userGetPlaylists:4ba12d2944e1c:theColorIsRed:cf2120) = 74047cab9aef19a7410b08f172baab4af6783912 token = cf212074047cab9aef19a7410b08f172baab4af6783912 The token sent by GrooveShark Flash: cf21200614a2d6513ec83aebf353d9fb6c02c398feb4a1 Maybe it's my SHA1 that is not computing properly? What do you get when you input those values in your GetRequestToken? |

Here is what I did: "getSearchResults:4ba134189baf0:theColorIsRed:a4b0e2" will be sha1 to "4d2c109390a5c133faf1df7aad47b6cdd2668a14" and afterwards with the randomHex "a4b0e24d2c109390a5c133faf1df7aad47b6cdd2668a14" |

Wow.. I get the same SHA1... this is so strange... Ok well I will keep trying ![]() Thanks a lot for your help ! |
