问题描述

请帮助！我已经把我的头发拉过这一个。：）

Please help! I have been pulling out my hair over this one. :)

我有一个网站，我需要HMAC SHA1进行身份验证。它目前使用另一种语言，但现在我需要移动到ColdFusion。对我的生活我不能得到的字符串匹配。。任何援助将非常感激。

I have a site that I need to HMAC SHA1 for authentication. It currently works with another language but now I need to move it to ColdFusion. For the life of me I cannot get the strings to match. Any assistance would be much appreciated.

两者都是Base64编码，然后URL编码。

Both are Base64 encoded and then URL encoded.

推荐答案

做一个HMAC-SHA1的事情我自己。最好的我可以说是，我发现这个旧的功能。为我迄今为止做的工作伟大。忘记了，我发现它虽然所以我不能贷的作者。

Doing an HMAC-SHA1 thing myself. Best I can say is that I found this old function. Has worked great for what I am doing thus far. Forgot where I found it though so I can't credit the author.

有关您的基地64的东西...运行在您的加密这个功能，那么就做一个CFSET newString =上返回什么toBase64（oldString）

For your Base 64 stuff... run this function on your encryption, then just do a cfset newString = toBase64(oldString) on what is returned.

<cffunction name="hmacEncrypt" returntype="binary" access="public" output="false">
   <cfargument name="signKey" type="string" required="true" />
   <cfargument name="signMessage" type="string" required="true" />
   <cfargument name="algorithm" type="string" default="HmacSHA1" />
   <cfargument name="charset" type="string" default="UTF-8" />

   <cfset var msgBytes = charsetDecode(arguments.signMessage, arguments.charset) />
   <cfset var keyBytes = charsetDecode(arguments.signKey, arguments.charset) />
   <cfset var keySpec = createObject("java","javax.crypto.spec.SecretKeySpec")  />
   <cfset var mac = createObject("java","javax.crypto.Mac") />

   <cfset key = keySpec.init(keyBytes, arguments.algorithm) />
   <cfset mac = mac.getInstance(arguments.algorithm) />
   <cfset mac.init(key) />
   <cfset mac.update(msgBytes) />

   <cfreturn mac.doFinal() />
</cffunction>
