Crockford Base32编码的经典实现

Question

从the first part of my problem开始，我现在正在尝试编写一个经典的Douglas Crockford's Base32 Encoding实现。

这个项目的时间很紧，所以当我自己解决这个问题时，我希望有人手头上有现成的东西(或者至少可以比我更快地完成一个)。

第一次运行...这看起来是对的吗？

'Base32 encoding functions for shorter, less confusing verification numbers'
Const kBase32Digits = "0123456789abcdefghjkmnpqrstvwxyz"
'To Base32'
Function ToBase32(ByVal lInput)
    Dim lModulo, sTemp
    Do Until lInput = 0
        lModulo = lInput Mod 32
        sTemp = Mid(kBase32Digits, lModulo + 1, 1) & sTemp
        lInput = lInput \ 32
    Loop
    ToBase32 = sTemp
End Function
'From Base32'
Function FromBase32(ByVal sInput)
    Dim sTemp, sR, i,iY,lLen, zMultiplier
    sTemp = LCase(sInput)
    sTemp = Replace(sTemp,"o","0")
    sTemp = Replace(sTemp,"i","1")
    sTemp = Replace(sTemp,"l","1")
    sTemp = Replace(sTemp,"u","v")
    zMultiplier = 1
    lLen = Len(sTemp)
    For i = lLen To 1 Step -1
        sR = Mid(sTemp, i, 1)
        iY = InStr(1, kBase32Digits, sR, vbTextCompare) - 1
        FromBase32 = FromBase32 + iY * zMultiplier
        zMultiplier = zMultiplier * 32
    Next
End Function

编辑:到目前为止，似乎工作得很好...除非有人贴出更好的东西，否则我会用这个的。
