我需要在我的应用程序中生成MD5。
我试过谷歌但只找到MD5的PHP代码。我需要连接到使用MD5哈希验证的客户端系统,但是他们的代码是PHP,我的是使用VBScript的Classic ASP。
我的服务器支持.Net,因此无法使用PHP脚本。在Classic ASP中是否有任何这样的VBScript MD5代码?

更新2017-02-21 - 现在为JWT添加了HMACSHA256
更新2016-07-05 - 现在添加了SHA1和SHA256
是的,对于那些一直在努力解决这个问题的人(比如我自己)而且想知道,这是有可能的!
以下代码分为几个函数,以便您可以将MD5 / sha1 / sha256作为字符串或文件。
我从另一个stackexchange借用了函数GetBytes和BytesToBase64,stringToUTFBytes中的代码基于另一个stackexchange。
function md5hashBytes(aBytes)
Dim MD5
set MD5 = CreateObject("System.Security.Cryptography.MD5CryptoServiceProvider")
MD5.Initialize()
'Note you MUST use computehash_2 to get the correct version of this method, and the bytes MUST be double wrapped in brackets to ensure they get passed in correctly.
md5hashBytes = MD5.ComputeHash_2( (aBytes) )
end function
function sha1hashBytes(aBytes)
Dim sha1
set sha1 = CreateObject("System.Security.Cryptography.SHA1Managed")
sha1.Initialize()
'Note you MUST use computehash_2 to get the correct version of this method, and the bytes MUST be double wrapped in brackets to ensure they get passed in correctly.
sha1hashBytes = sha1.ComputeHash_2( (aBytes) )
end function
function sha256hashBytes(aBytes)
Dim sha256
set sha256 = CreateObject("System.Security.Cryptography.SHA256Managed")
sha256.Initialize()
'Note you MUST use computehash_2 to get the correct version of this method, and the bytes MUST be double wrapped in brackets to ensure they get passed in correctly.
sha256hashBytes = sha256.ComputeHash_2( (aBytes) )
end function
function sha256HMACBytes(aBytes, aKey)
Dim sha256
set sha256 = CreateObject("System.Security.Cryptography.HMACSHA256")
sha256.Initialize()
sha256.key=aKey
'Note you MUST use computehash_2 to get the correct version of this method, and the bytes MUST be double wrapped in brackets to ensure they get passed in correctly.
sha256HMACBytes = sha256.ComputeHash_2( (aBytes) )
end function
function stringToUTFBytes(aString)
Dim UTF8
Set UTF8 = CreateObject("System.Text.UTF8Encoding")
stringToUTFBytes = UTF8.GetBytes_4(aString)
end function
function bytesToHex(aBytes)
dim hexStr, x
for x=1 to lenb(aBytes)
hexStr= hex(ascb(midb( (aBytes),x,1)))
if len(hexStr)=1 then hexStr="0" & hexStr
bytesToHex=bytesToHex & hexStr
next
end function
Function BytesToBase64(varBytes)
With CreateObject("MSXML2.DomDocument").CreateElement("b64")
.dataType = "bin.base64"
.nodeTypedValue = varBytes
BytesToBase64 = .Text
End With
End Function
'Special version that produces the URLEncoded variant of Base64 used in JWTs.
Function BytesToBase64UrlEncode(varBytes)
With CreateObject("MSXML2.DomDocument").CreateElement("b64")
.dataType = "bin.base64"
.nodeTypedValue = varBytes
BytesToBase64UrlEncode = replace(replace(replace(replace(replace(.Text,chr(13),""),chr(10),""),"+", "-"),"/", "_"),"=", "")
End With
End Function
Function GetBytes(sPath)
With CreateObject("Adodb.Stream")
.Type = 1 ' adTypeBinary
.Open
.LoadFromFile sPath
.Position = 0
GetBytes = .Read
.Close
End With
End Function
这些可以使用如下:
BytesToBase64(md5hashBytes(stringToUTFBytes("Hello World")))
制作:sQqNsWTgdUEFt6mb5y4 / 5Q ==
bytesToHex(md5hashBytes(stringToUTFBytes("Hello World")))
产品:B10A8DB164E0754105B7A99BE72E3FE5
对于SHA1:
bytesToHex(sha1hashBytes(stringToUTFBytes("Hello World")))
产品:0A4D55A8D778E5022FAB701977C5D840BBC486D0
对于SHA256:
bytesToHex(sha256hashBytes(stringToUTFBytes("Hello World")))
产品:A591A6D40BF420404A011733CFB7B190D62C65BF0BCDA32B57B277D9AD9F146E
获取文件的MD5(对Amazon S3 MD5检查很有用):
BytesToBase64(md5hashBytes(GetBytes(sPath)))
其中sPath是本地文件的路径。
最后,创建一个JWT:
'define the JWT header, needs to be converted to UTF bytes:
aHead=stringToUTFBytes("{""alg"":""HS256"",""typ"":""JWT""}")
'define the JWT payload, again needs to be converted to UTF Bytes.
aPayload=stringToUTFBytes("{""sub"":""1234567890"",""name"":""John Doe"",""admin"":true}")
'Your shared key.
theKey="mySuperSecret"
aSigSource=stringToUTFBytes(BytesToBase64UrlEncode(aHead) & "." & BytesToBase64UrlEncode(aPayload))
'The full JWT correctly Base 64 URL encoded.
aJWT=BytesToBase64UrlEncode(aHead) & "." & BytesToBase64UrlEncode(aPayload) & "." & BytesToBase64UrlEncode(sha256HMACBytes(aSigSource,stringToUTFBytes(theKey)))
哪个会产生以下有效的JWT: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiYWRtaW4iOnRydWV9.7ofvtkn0z_pTl6WcqRTxw-4eSE3NqcEq9_3ax0YcuIQ

首先,谢谢SgtWilko! :)
根据您收集的信息,我为所有人完成了一项功能(不适用于base64 / Files)。
你的代码对我来说非常有用,但我正在寻找一个更像PHP的(简单)函数来处理纯文本和更明确的代码。
编辑:
根据问题How to hash a UTF-8 string in Classic ASP,我提出了ADODB.Stream解决方案。您现在可以使用非英文字符。
编辑:
参数 PlainText 已更改为目标。
您现在可以使用 HMAC 版本
只需将Target参数用作数组。
Target(0) = PlainText
Target(1) = SharedKey
再次感谢SgtWilko;)
Announcing the first SHA1 collision(Google安全博客)2017年2月23日。
使用此功能,您可以将纯文本哈希到:
MD5,RIPEMD160,SHA1,SHA256,SHA384,SHA512,HMACMD5,HMACRIPEMD160,HMACSHA1,HMACSHA256,HMACSHA384和HMACSHA512
如果您需要更多信息,可以在System.Security.Cryptography Namespace

On Error Resume Next
Dim PlainText
If IsArray(Target) = True Then PlainText = Target(0) Else PlainText = Target End If
With CreateObject("ADODB.Stream")

End With
Set UTF8Encoding = CreateObject("System.Text.UTF8Encoding")
Dim PlainTextToBytes, BytesToHashedBytes, HashedBytesToHex
PlainTextToBytes = UTF8Encoding.GetBytes_4(PlainText)

有Javascript代码可以生成MD5校验和。其中一个源自Google闭包库的是available here。
从Javascript生成Windows脚本组件非常容易,然后从任何支持COM的语言(包括VB)调用该组件。
