Kyatric found something error on getting sha1
the string is
1509710152jg4g3b0i-7pb0-92y5-mu0a-e997nmb6gg3p{"channelid":"guangzhou1","gameid":"ninedead","roomid":"568bc11c-504c-4be8-9104-0be6b0cc2375","player":{"uid":"1830969817","name":"mr.yipxx","avatarurl":"http://s1.yy.com/guild/header/10001.jpg","opt":""}}FEDCDTCYQDLTFAWJ
the sha1 got by cbhash is c55c6794d4f76d87aaf8139ecda5b875a2e7c30b
but the right sha1 is C7961CC7357F8A991EDF5A93DAF1E69B2D7C30AB by any sha1 verifying site like http://www.convertstring.com/en/Hash/SHA1
is the " in the string made this mistake? or just my bad?
