Poco 密码泄露
Poco Cipher leak
我快要疯了，在我用谷歌搜索没有答案之后，我将尝试写在这里。
我有 Ubuntu 16.04、GCC 5.4.0、Poco 1.7.8-all 和 OpenSSL 1.1.0e。
以及这几行代码：
int main()
{
const std::string AES_NAME = "aes-128-cbc";
Cipher::Ptr uptrCipher = CipherFactory::defaultFactory().createCipher(CipherKey(AES_NAME, "abcdef", "123456"));
std::string plainText = "This is my secret information";
std::string encrypted = uptrCipher->encryptString(plainText, Cipher::ENC_BASE64);
return 0;
}
如果我 运行 Valgrind 我得到这个错误（我为长度道歉）：

根据底部的最后陈述，我在第 100 行进入 Cipher.cpp 和 CipherImp.cpp 我发现：
#if OPENSSL_VERSION_NUMBER >= 0x10100000L
_pContext = EVP_CIPHER_CTX_new();
好像没删。。。不知道。但我确定我犯了一些错误。
有人遇到过这个错误吗？
我的代码哪里错了？
谢谢
克里斯塔诺
我找到了答案。
似乎使用 OpenSSL 1.1.0 释放资源的方法是 EVP_CIPHER_CTX_free(ctx)。
我在我的项目中包含了 CipherImpl 并在 distructor 中更改了以下行：
CryptoTransformImpl::~CryptoTransformImpl()
{
#if OPENSSL_VERSION_NUMBER >= 0x10100000L
//IT WAS: EVP_CIPHER_CTX_cleanup(_pContext);
EVP_CIPHER_CTX_free(_pContext);
#else
EVP_CIPHER_CTX_cleanup(&_context);
#endif
}
我再次运行 Valgrind:

我快要疯了，在我用谷歌搜索没有答案之后，我将尝试写在这里。 我有 Ubuntu 16.04、GCC 5.4.0、Poco 1.7.8-all 和 OpenSSL 1.1.0e。
以及这几行代码：
int main()
{
const std::string AES_NAME = "aes-128-cbc";
Cipher::Ptr uptrCipher = CipherFactory::defaultFactory().createCipher(CipherKey(AES_NAME, "abcdef", "123456"));
std::string plainText = "This is my secret information";
std::string encrypted = uptrCipher->encryptString(plainText, Cipher::ENC_BASE64);
return 0;
}
如果我 运行 Valgrind 我得到这个错误（我为长度道歉）：

根据底部的最后陈述，我在第 100 行进入 Cipher.cpp 和 CipherImp.cpp 我发现：
#if OPENSSL_VERSION_NUMBER >= 0x10100000L
_pContext = EVP_CIPHER_CTX_new();
好像没删。。。不知道。但我确定我犯了一些错误。
有人遇到过这个错误吗？ 我的代码哪里错了？
谢谢
克里斯塔诺
我找到了答案。
似乎使用 OpenSSL 1.1.0 释放资源的方法是 EVP_CIPHER_CTX_free(ctx)。
我在我的项目中包含了 CipherImpl 并在 distructor 中更改了以下行：
CryptoTransformImpl::~CryptoTransformImpl()
{
#if OPENSSL_VERSION_NUMBER >= 0x10100000L
//IT WAS: EVP_CIPHER_CTX_cleanup(_pContext);
EVP_CIPHER_CTX_free(_pContext);
#else
EVP_CIPHER_CTX_cleanup(&_context);
#endif
}
我再次运行 Valgrind:
