脚本宝典收集整理的这篇文章主要介绍了UE4 CryptoPP 5.6.5 加解密矩阵验证结果，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
Crypto++ 5.6.5
密码与偏移量：
static SecByteBlock GetKey(std::string KeyStr)
{
SecByteBlock key(AES::MAX_KEYLENGTH);
memset(key, 0x30, key.size());
KeyStr.size() <= AES::MAX_KEYLENGTH ? memcpy(key, KeyStr.c_str(), KeyStr.size()) : memcpy(key, KeyStr.c_str(), AES::MAX_KEYLENGTH);
return key;
}
//convert string to byte
static SecByteBlock GetIV(std::string KeyStr, const std::string IVStr)
{
SecByteBlock IV(AES::BLOCKSIZE);
memset(IV, 0x30, IV.size());
KeyStr.size() <= AES::BLOCKSIZE ? memcpy(IV, IVStr.c_str(), IVStr.size()) : memcpy(IV, IVStr.c_str(), AES::BLOCKSIZE);
return IV;
}
