OpenSSL私钥读取错误（PEM_read_bio_RSAPrivateKey）

Question

我正在尝试通过openSSL和VC ++读取PrivateKey，我收到此错误“OpenSSL error: error:0906D064:lib(9):func(109):reason(100)”..

我的私钥：

我正在使用WinXP-SP2和MS-Visual Studio 2008 .. 我在这一行收到错误：rsa_private = PEM_read_bio_RSAPrivateKey(mem, NULL, NULL, NULL); 错误：（OpenSSL error: error:0906D064:lib(9):func(109):reason(100)）

任何人都可以帮助我，我该怎么读这个女贞钥匙????

感谢.....

Answer 1

变量private_key被错误地初始化。您需要在私钥中的每一行后添加\n。

Answer 2

对我有用

unsigned char *rsaPrivateKeyChar = (unsigned char *)key.c_str();
// write char array to BIO
BIO *rsaPrivateBIO = BIO_new_mem_buf(rsaPrivateKeyChar, -1);
// create a RSA object from private key char array
RSA *rsaPrivateKey = NULL;
PEM_read_bio_RSAPrivateKey(rsaPrivateBIO, &rsaPrivateKey, NULL, NULL);
return rsaPrivateKey;
