我使用openssl庫編寫了簡單的RSA密鑰函數。以下是我的代碼,我無法找到第二個PEM_read_RSAPrivateKey函數無效的原因。 有人可以幫助我嗎?PEM_read_RSAPrivateKey函數返回NULL
{
RSA* pRSA;
RSA* pRET;
pRSA = RSA_generate_key(1024, 65535, NULL, NULL);
if (RSA_check_key(pRSA) != 1) return (FALSE);
FILE* f;
char* pPIN = RAS_PINKEY;
f = fopen("testPRI.cap", "w");
PEM_write_RSAPrivateKey(f, pRSA, NULL, NULL, 0, NULL, NULL);
fclose(f);
f = fopen("testPRI.cap", "r");
pRET = PEM_read_RSAPrivateKey(f, &pRSAPRI, NULL, NULL);
fclose(f);
// pRET is valid (OK)
//-----
f = fopen("testPRI2.cap", "w");
PEM_write_RSAPrivateKey(f, pRSA, EVP_aes_128_cbc(), NULL, 0, NULL, "mypassword");
fclose(f);
f = fopen("testPRI2.cap", "r");
pRET = PEM_read_RSAPrivateKey(f, &pRSAPRI, NULL, "mypassword");
fclose(f);
// pRET is NULL (Why?)
}
testPRI.cap是

'pRSAPRI'聲明在哪?它是如何初始化的? – jww
pRSAPRI是全局變量,聲明爲RSA * pRSAPRI = RSA_new(); – user727062
即使第二個參數爲NULL,我也得到了相同的錯誤,例如PEM_read_RSAPrivateKey(f,NULL,NULL,「mypassword」); – user727062
