问题描述
SHA1(data, length, hash);
unsigned char *labelPtr;
labelPtr = hash;
mpz_set_str (encrypted, labelPtr, 16);
gmp_printf("hashed= %Zd\n", encrypted);
encrypted 等于 0?我需要从这个散列中获取一个整数，以便我可以执行 RSA 加密.我在调试时看到散列，但似乎无法将其转换为 int.它是 SHA-512 所以 512 位?奇怪的字符来自 printf("%s",hash);atoi 也给出 0，我是否必须按字符分解散列?我认为那会奏效.
encrypted equals 0?I need to get an integer from this hash so that I can perform RSA encryption. I see the hash when I debug, but cannot seem to turn this into an int. It is SHA-512 so 512 bits?Weird characters come out of printf("%s",hash);atoi gives 0 too, do I have to break up the hash by character? That would work I think.
推荐答案
mpz_set_str 第二个参数必须是字符串.
mpz_set_str second parameter must be a string.
您传递给 SHA1 函数的 hash 参数可能不是字符串.将其转换为字符串格式，然后再将其传递给 mpz_set_str 函数.
The hash argument you pass to SHA1 function is probably not a string. Convert it to a string format before passing it to the mpz_set_str function.
