我在使用cf9加密和解密功能时遇到问题。具体来说,我使用的代码需要能够使用AES / ECB / PKCS5Padding 256加密。我正在尝试使用以下代码将数据发布到第三方银行:
<cfparam name="theKey" default="someStaticKey">
<cfset strName = leaddetail.leadlast&','&leaddetail.leadfirst />
<cfset stFields = {requesttype = "eftaddonetimecompletetransaction"
,clientid = "XXXXXX"
,urltoredirect = "#RedirectURl#"
,customerid = "#leaddetail.leadid#"
,isdebitcardonly = "No"
,customername = "#strName#"
,customeraddress1 = "#form.billingaddress#"
,customercity = "#form.billingcity#"
,customerstate = "#form.billingstate#"
,customerzip = "#form.billingzip#"
,cardbillingaddr1 = "#form.billingaddress#"
,cardbillingcity = "#form.billingcity#"
,cardbillingstate = "#form.billingstate#"
,cardbillingzip = "#form.billingzip#"
,accounttype = "CC"
,name_on_card = "#form.leadname#"
,accountnumber = "#form.ccacctnum#"
,expmonth = "#Left(form.ccexpdate,2)#"
,expyear = "#Right(form.ccexpdate,2)#"
,cvvcode = "#form.ccv2#"
,amount = "#NumberFormat(esigninfo.esignpayamt,'9999.99')#"
,startdate = "#DateFormat(Now(),'YYYY-MM-DD')#"
,transactiontypecode = "WEB"}/>
<cfset theEncryptedStr = ToBase64(encrypt(serializeJson(stFields),theKey))>

由于某种原因我可以加密,但无法解密响应。是否有人有更多的经验,可以走上成功的道路?

我使用以下脚本解密我的cfhttp响应字符串:
<cfset content = httpResponse.filecontent>
<cfset authdata = structNew()>
<cfloop index="line" list="#content#">
<cfset dtype = listFirst(line, "=")/>
<cfset EncodedString = listRest(line, "=")/>
<cfset authdata[dtype] = EncodedString />
</cfloop>
<cfscript>
keyInBase64 = "Some64baseKey;
// Now decrypt the base64 encoded encryption string
decryptedValue = decrypt(EncodedString , keyInBase64 , "AES/ECB/PKCS5Padding" , "base64" );
WriteDump(variables);
</cfscript>
我尝试解密的字符串类似于以下内容:
nvpvar = fKsJGJ-Fe系2zoqUROAeE8N8a87USuQpE7dVd5IvRa67cHsVkPwx9taKLuXKwsCKFC_-NW3j6IOQAvCnRNc4cRNfq2fqyRHBUrFbFDCCmwpk =
答案 0 :(得分:6)
encrypt(serializeJson(stFields),theKey)
首先,这是非 AES加密。您省略了algorithm
参数,因此encrypt()默认为遗留CFMX_COMPAT算法(最弱)。 CFMX_COMPAT它不是真正的&#34;加密算法,所以不要使用它 - 任何事情!
其次,使用AES,您limited to 128 bit keys out of the box。要使用256位密钥,必须先安装(JCE) Unlimited Strength Jurisdiction Policy Files。
将它们复制到
/lib/security/
目录中。然后重新启动CF服务器以应用更改。注意:如果安装了多个JVM, 一定要更新正确的。即列出的那个 CF管理员)。
重新启动后,您将能够使用256位密钥进行加密。使用ECB模式时,语法为:encrypt(string, key, algorithm, encoding)
string
- 要加密的纯文本key
- 256位密钥,必须是base64编码的algorithm
- 表示所需的单个字符串:算法,模式和填充方案。注意:&#34; AES&#34;实际上是更长时间的简写&#34; AES / ECB / PKCS5Padding&#34; encoding
- &#34;将数据表示为字符串的二进制编码&#34; 全部放在一起:
<cfscript>
// some sample data to encrypt
stFields = { clientid = "AA-BB-CC-123"
, customername = "ABC Incorporated"
};
// some 256 bit key, must be base64 encoded
// hard coded for demo purposes only
keyInBase64 = "9NJU2L3FZ8Rr0WKZUFC3lyE/yRrQ7sIZmQRk3kx9MLE=";
// AES encrypt the value, and base64 encode the result
encryptedValue = encrypt( serializeJson(stFields)
, keyInBase64
, "AES/ECB/PKCS5Padding"
, "base64"
);
// Now decrypt the base64 encoded encryption string
decryptedValue = decrypt( encryptedValue
, keyInBase64
, "AES/ECB/PKCS5Padding"
, "base64"
);
// display results
WriteDump( variables );
</cfscript>
根据评论进行更新:
我注意到你正在操纵原始的http响应字符串。没有看到API,我猜想要么a)你需要先解密整个字符串,然后提取部分 - 或 - b)代码没有正确提取值,这就是为什么你不能解密它。 cfloop将响应视为逗号分隔列表。根据变量名称,我猜它实际上是由新行分隔,即:
param1=xxxxx -- new line
param2=yyyyy -- new line
param3=zzzzz
但这些只是猜测。检查您的API。返回的响应的实际格式是什么?另外,您能否{@ 3}}包含完整错误消息?
