我找到了从Java JNI调用的C ++ API。 libcma.so包含方法Java_com_smule_android_network_core_NetworkUtils_makeDigest，该方法将创建摘要-我认为它是MD5。
以下是相反的来源：
https://raw.githubusercontent.com/Bizarrus/Sing/master/cma.cpp
这是JNI的定义：
谁能告诉我将使用哪个Algorithm？

在POST请求中，Query-Argument **摘要is the哈希of the request. These摘要will be created by Java_com_smule_android_network_network_core_NetworkUtils_makeDigest (i think). I don't know, which data will be used for the哈希算法{{1 }}摘要具有以下参数：
- I've tried to reproduce the（按字母顺序排列）不包括Query-Parameters-参数（这些方法将在JavaScript的网站上使用。我尝试了一些数据组合来重现digest，但是我没有找到解决方案，这些数据都代表了原始摘要。
从digest头上的Response将被X-Smule-Digest散列，这是我上周复制的。这里（在MD5中）是一个用于计算PHP的工作示例：
X-Smule-Digest答案 0 :(得分：1)
1。您指定的摘要长度为40个字符，包含从0到9的数字和从a到f的字母。因此它是40个十六进制值。因此，很可能是使用SHA-1摘要函数创建的。
2。您指定的C ++函数具有以下签名：
int32_t Java_com_smule_android_network_core_NetworkUtils_makeDigest(int32_t * a1, int32_t a2, int32_t a3)
Java源代码中的相应签名为：
private static native String makeDigest(String str, byte[] bArr);
第一个参数a1可以是JNI环境保留的指针。因此，预留a1输入，该函数接受两个参数：一个字符串和一个字节数组，并返回一个字符串：摘要。对于我来说，C ++代码本身太复杂了。
3。您指定的Java文件中两次使用了此JNI函数。在函数m18107a和m18106a中。让我们在源代码中添加一些注释：
// Function that takes three arguments :
// - a list of pairs of string we will call the "json pairs"
// - a string we will call the "secret"
// - an other string we will call the "optional token"
// and return the returned string of makeDigest which may be the digest.
public static String m18107a(List<Pair<String, String>> list, String str, String str2)
{
// Sort the json pairs alphabetically according to the first string of each pairs.
// (Check the source code of C35442 to verify my statement, I may be wrong )
Collections.sort(list, new C35442());
// Create a single string, that concatenate all the json pairs.
// ( I guess { age : 21, name : "bob" } becomes "age21namebob" )
// We will call that the "digest input"
StringBuilder stringBuilder = new StringBuilder();
for (Pair pair : list) {
stringBuilder.append((String) pair.first).append((String) pair.second);
}
// Append the "digest input" just created with the "optional token" if it exists.
if (str2 != null) {
stringBuilder.append(str2);
}
// Send the "secret" string, and the "digest input" as BYTES (may be important)
// Return the digest computed as returned string of the function.
return makeDigest(str, stringBuilder.toString().getBytes());
}
// Function that takes four arguments :
// - a string str
// - a number j
// - a string str2
// - a string str3 (can be null, as seen later)
// and return the returned string of makeDigest which may be the digest.
public static String m18106a(String str, long j, String str2, String str3)
{
// Create a single string, that concatenate j and str2.
// We will call that the "digest input"
StringBuilder append = new StringBuilder().append("").append(j).append(str2);
// If str3 is null, make it empty.
if (str3 == null) {
str3 = "";
}
// Send the "secret" string, and the "digest input" concatenated with str3, as BYTES (may be important).
// Return the digest computed as returned string of the function.
return makeDigest(str, append.append(str3).toString().getBytes());
}
很难走得更远。尝试挖掘一些东西：
m18107a和m18106a在哪里叫？您至少可以找到这些输入的内容吗？这样您就可以发挥出色的输入效果。
