根据我的阅读,DNN 默认使用“SHA1”哈希。@barnyr发布的线程显示它只是对连接的盐和密码进行哈希处理,但有一些曲折。
鉴于 CF9 的Hash
函数不接受二进制(在 CF11 中支持),我认为仅使用原生 CF 函数无法复制结果。相反,我建议将字符串解码为二进制,然后直接使用 java:
代码:
<cfscript>
thePassword = "DT!@12";
base64Salt = "+muo6gAmjvvyy5doTdjyaA==";
// extract bytes of the salt and password
saltBytes = binaryDecode(base64Salt, "base64");
passBytes = charsetDecode(thePassword, "UTF-16LE" );
// next combine the bytes. note, the returned arrays are immutable,
// so we cannot use the standard CF tricks to merge them
ArrayUtils = createObject("java", "org.apache.commons.lang.ArrayUtils");
dataBytes = ArrayUtils.addAll( saltBytes, passBytes );
// hash binary using java
MessageDigest = createObject("java", "java.security.MessageDigest").getInstance("SHA-1");
MessageDigest.update(dataBytes);
theBase64Hash = binaryEncode(MessageDigest.digest(), "base64");
WriteOutput("theBase64Hash= "& theBase64Hash &"<br/>");
</cfscript>
差异演示:
<cfscript>
theEncoding = "UTF-16LE";
thePassword = "DT!@12";
base64Salt = "+muo6gAmjvvyy5doTdjyaA==";
// extract the bytes SEPARATELY
saltBytes = binaryDecode(base64Salt, "base64");
passBytes = charsetDecode(thePassword, theEncoding );
ArrayUtils = createObject("java", "org.apache.commons.lang.ArrayUtils");
separateBytes = ArrayUtils.addAll( saltBytes, passBytes );
// concatenate first, THEN extract the bytes
theSalt = charsetEncode( binaryDecode(base64Salt, "base64"), theEncoding );
concatenatedBytes = charsetDecode( theSalt & thePassword, theEncoding );
// these are the raw bytes BEFORE hashing
WriteOutput("separateBytes= "& arrayToList(separateBytes, "|") &"<br>");
WriteOutput("concatenatedBytes"& arrayToList(concatenatedBytes, "|") );
</cfscript>
结果:
separateBytes = -6|107|-88|-22|0|38|-114|-5|-14|-53|-105|104|77|-40|-14|104|68|0|84|0|33|0|64|0|49|0|50|0
concatenatedBytes = -6|107|-88|-22|0|38|-114|-5|-14|-53|-105|104|-3|-1|68|0|84|0|33|0|64|0|49|0|50|0
