用VBS模拟实现PHP的sha1_file函数效果代码,需要的朋友可以参考下。

代码如下:

Function sha1_file(filename, raw_output)

Dim HashedData, Utility, Stream

Set HashedData = CreateObject("CAPICOM.HashedData")

Set Utility = CreateObject("CAPICOM.Utilities")

Set Stream = CreateObject("ADODB.Stream")

HashedData.Algorithm = 0

Stream.Type = 1

Stream.Open

Stream.LoadFromFile filename

Do Until Stream.EOS

HashedData.Hash Stream.Read(1024)

Loop

If raw_output Then

sha1_file = Utility.HexToBinary(HashedData.Value)

Else

sha1_file = HashedData.Value

End If

End Function
