unsigned char *ivec:初始向量 const int enc:加解密模式(AES_ENCRYPT 代表加密, AES_DECRYPT代表解密) void AES_cfb128_encrypt(const unsigned char *in, unsigned char *out, size_t length, const AES_KEY *key, unsigned char *ivec, int *num, const int enc) 功能:以CFB128位模式加密/解密数据块。
此外,为了确保加密和解密的成功,输入文件和输出文件的路径需要是有效的,并且程序需要有相应的权限才能进行文件的读写操作。 AES(Advanced Encryption Standard)是一种对称加密算法,用于对数据进行加密和解密。Linux操作系统提供了一些命令行工具,可以使用AES算法对文件或数据进行加密和解密。下面是几个常用的Linux命令。 1...
AES(Advanced Encryption Standard)算法是一种常见的对称加密算法,其具体的加密传输流程如图1所示: 图1 AES数据加密流程 对于对称加密算法而言发送端和接收端使用相同的密钥K,而加密函数E(P,K)和解密函数D(C,K)是一组逆运算。 对称加密算法的优势是算法公开、计算量小、加密速度快、加密效率高。其安全性主要由密...
{[keysrc_encryption]kup_key[encryption=aes, aeskeyfile=user_data_kup_key_example.nky, load=0x04000000]data.bin} 上面的data.bin是明文文件; user_data_kup_key_example.nky是AES的密钥。如果不存在AES的密钥, 工具bootgen会自动生成密钥。 生成密钥后,需要更新文件xilsecure_aes_example.c。 在“Xilinx...
