vbs获取md5值最简单的方法是直接调用capicom组件，但是由于capicom组件系统并不是默认安装，所以使用起来不方便

下面这个代码不需要组件一样可以获取md5值。

代码如下:

option explicit

dim wi

dim file

dim file_size

dim file_attributes

dim file_version

dim file_hash

set wi = createobject(windowsinstaller.installer)

file = 111.exe

file_size = wi.filesize(file)

file_attributes = wi.fileattributes(file)

file_version = wi.fileversion(file)

file_hash = getfilehash(file)

set wi = nothing

msgbox file: & file & vbcrlf & _

size: & file_size & vbcrlf & _

attributes: & file_attributes & vbcrlf & _

version: & file_version & vbcrlf & _

md5: & file_hash

function getfilehash(file_name)

dim file_hash

dim hash_value

dim i

set file_hash = wi.filehash(file_name, 0)

hash_value =

for i = 1 to file_hash.fieldcount

hash_value = hash_value & bigendianhex(file_hash.integerdata(i))

next

getfilehash = hash_value

set file_hash = nothing

end function

function bigendianhex(int)

dim result

dim b1, b2, b3, b4

result = hex(int)

b1 = mid(result, 7, 2)

b2 = mid(result, 5, 2)

b3 = mid(result, 3, 2)

b4 = mid(result, 1, 2)

bigendianhex = b1 & b2 & b3 & b4

end function
