Habbo Packet Deciphering

[zgillis]

I am coding a Habbo v18 emulator in C#, and have handled the first few packets on connection between the client and the server. First, I have decided to code the registration system. I am to the point of sending this packet to the client:

DARAHIIIKHJIPAIQAdd-MM-yyyy..@H[100,105,110,115,120,125,130,135,140,145,150,155,160,165,170,175,176,177,178,180,185,190,195,200,205,206,207,210,215,220,225,230,235,240,245,250,255,260,265,266,267,270,275,280,281,285,290,295,300,305,500,505,510,515,520,525,530,535,540,545,550,555,565,570,575,580,585,590,595,596,600,605,610,615,620,625,626,627,630,635,640,645,650,655,660,665,667,669,670,675,680,685,690,695,696,700,705,710,715,720,725,730,735,740].

I am wondering how this packet is structured, what is is/does, and how I should generate it/or just send it exactly the way it appears. What meaning does the data in this packet have?
