RSASSA_PKCS1v15_SHA_Signer和PK_SignatureScheme :: KeyTooShort异常 [英] RSASSA_PKCS1v15_SHA_Signer and PK_SignatureScheme::KeyTooShort exception
本文介绍了RSASSA_PKCS1v15_SHA_Signer和PK_SignatureScheme :: KeyTooShort异常的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我第一次使用Crypto ++，我有一些麻烦。为什么这在C＃（使用相同的键），但不是与Crypto ++工作？我将在下面显示我的C＃和C ++代码。
C＃代码（this works！）：

感谢任何帮助，Hetelek。
解决方案我不能回答为什么这在C＃，但对于Crypto ++，有几个问题。
首先，您可能调用了 Integer 。我想你希望这个从大端字节数组转换的数据：
整数（const byte * encodedInteger，size_t byteCount，Signedness s = UNSIGNED）
，但使用 this one 从基础2,8,10或16（在您的情况下是10）中的字符串转换。
因此，使用 ExponentCON 为例，您应该这样做：
const int ExponentSize（0x4）;
const byte ExponentCON [ExponentSize] = {0x00，0x01，0x00，0x01};
Integer integ1（ExponentCON，ExponentSize）;
或可能更好：
std :: string ExponentCON（101h）; // < - 注意尾随'h'表示十六进制编码
整数integ1（ExponentCON.c_str（））;
InvertibleRSAFunction 的成员必须满足特定条件才能成为有效的键。您可以通过 InvertibleRSAFunction :: Validate 函数，我假设检查描述的条件
params.Validate（rng，3）; //为您的输入数据返回false
有一些帮助函数被设计为避免必须明确地设置一切。我不知道这些是否适合您，但我指的是 InvertibleRSAFunction :: GenerateRandomWithKeySize 和重载的 InvertibleRSAFunction :: Initialize 。
Crypto ++ Wiki 介绍了使用这些函数与示例代码。
I am using Crypto++ for the first time, and I am having some trouble. Why does this work in C# (with the same keys), but not with Crypto++? I will show my C# and C++ code below.

Based on what I know, Crypto++'s 'RSASSA_PKCS1v15_SHA_Signer' is what I want equivalent to C#'s 'RSAPKCS1SignatureFormatter' and setting the hash algorithm to SHA1.
The error it throws is:
Unhandled exception at at 0x7646B9BC in proj.exe: Microsoft C++ exception: > CryptoPP::PK_SignatureScheme::KeyTooShort at memory location 0x0040EF18.
Thanks for any help, Hetelek.
解决方案 I can't answer as to why this works in C#, but as for Crypto++, there are a couple of issues.
Firstly, you're probably invoking the wrong constructor of Integer. I guess you want this one which converts from big-endian byte array:
Integer (const byte *encodedInteger, size_t byteCount, Signedness s=UNSIGNED)
but are using this one which convert from a string in base 2, 8, 10, or 16 (in your case base 10).
So, using ExponentCON as an example, you should do:
const int ExponentSize(0x4);
const byte ExponentCON[ExponentSize] = { 0x00, 0x01, 0x00, 0x01 };
Integer integ1(ExponentCON, ExponentSize);
or possibly better still:
std::string ExponentCON("101h"); // <-- Note trailing 'h' indicating hex encoding
Integer integ1(ExponentCON.c_str());
Next, the members of InvertibleRSAFunction must satisfy certain conditions in order to qualify as a valid key. These can be seen by stepping through the InvertibleRSAFunction::Validate function and I assume check for the conditions described here.
params.Validate(rng, 3); // Returns false for your input data
There are some helper functions which are designed to avoid having to set everything explicitly as you're doing. I don't know if these are suitable for you, but I'm referring to InvertibleRSAFunction::GenerateRandomWithKeySize and the overloaded InvertibleRSAFunction::Initialize.
The Crypto++ Wiki describes the use of these functions with example code.
