c++ - 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 .. 我在这一行出现错误：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，我应该如何阅读这个私有密钥？？？？

谢谢.....

Answer 1

变量private_key初始化错误。您需要\n在私钥的每一行之后添加。

Answer 2

这个对我有用

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;
