’介绍说明:只针对alpha2
TYIIIIIIIIIIIIIIII这样加密来解密
没有做更多容错处理只是解出下载urlexe地址
般情况下该url加密
串是RHptd4的后(去掉最后4个) Dim enTmp,enstr,a,bb
enstr=Str2Hex("RHptd4RPFZVOdoVQTrvWTnTp4n6PVN6QTop1tnau1hsU")
For i = 1 To Len(enStr) step 6
enTmp =Array(Mid(enStr,i,6)&"00")
sz =Split(enTmp(0), ",", -1, 1)
a= right(sz(0), 1) Xor left(sz(1), 1)
bb=bb& a&right(sz(1), 1)
Next
Function Str2Hex(ByVal strHex)
Dim sHex
For i = 1 To Len(strHex) step 1
sHex = sHex & Hex(Asc(Mid(strHex,i,1)))&","
Next
Str2Hex = sHex
End Function
Function Hex2Str(hexStr)
Dim sstr,hextmp
For i = 1 To Len(hexStr) step 2
hexTmp = Mid(hexStr,i,2)
If hexTmp <> "00" Then
sstr = sstr & ChrW("&h" & hexTmp)
End If
Next
Hex2Str = sstr
End Function
wscript.echo Hex2Str(bb)
