在Openssl中,非对称加密涉及到两个密钥.一个为公开的密钥(公钥),一个为非公开的密钥.而OpenSSL中非对称加密算法有RSA.DSA.ECC,他们的原理不同,因此其密钥结构不同.下面我们列出我们关心的密钥部分. 1)非对称算法密钥结构 OpenSSL中,生产密钥的算法通过以下几个函数 int RSA_generate_key_ex(RSA *rsa, int bits, BIGNUM *e, BN_GENCB *cb); int DSA_generate_key(DSA *dsa); i

下面来自wikipedia: In computer science, a union is a value that may have any of several representations or formats; or it is a data structure that consists of a variable which may hold such a value. Some programming languages support special data types,
Linux C/C++编程时常会遇到“error: expected expression before ‘struct’”错误,此错误一般是由未定义的宏(宏里套宏)或参量引起,导致编译器判断当前语句为非法语句,可能有如下几种情况. 1.缺少ioctl.h头文件 调用ioctl函数,用到参数VIDIOC_QUERYCAP时无法编译通过. 解决办法: #include <sys/ioctl.h> 2.#define错误 比如: #define X =5 int z=X+1; 解决办法: 修正#d
