openssl.net rsa加密工作示例需要
有没有人使用OpenSSL.NET进行RSA加密的任何工作示例？ 我想使用以PEM格式存储的私钥来加密一些数据。
我创建一个OpenSSL.Crypto.RSA对象并希望使用PrivateEncrypt方法，但它抛出OpenSSLException而没有其他数据（空Errors数组，没有内部exception）。 在使用PrivateEncrypt方法之前，我使用从命令openssl rsa -in private_key.pem -text -noout读取的数据填充所有属性（如PublicModulus，PrivateExponent等）
有谁知道如何将PEM文件读入OpenSSL.Crypto.RSA对象或有任何其他工作加密示例？
这是Linux上的C / C ++，但是直到我痛苦地开始工作才发现这样的简单例子
生成关键命令行
openssl genrsa -out privkey.pem 2048
HelloWord.cpp
#include #include #include int main() { char *message = "Hello World"; unsigned char* encrypted = (unsigned char *) malloc(500); unsigned char* decrypted = (unsigned char *) malloc(500); int bufSize; FILE *keyfile = fopen("privkey.pem", "r"); RSA *rsa = PEM_read_RSAPrivateKey(keyfile, NULL, NULL, NULL); printf("\n\nStarting Message = %s\n", message); if (rsa == NULL) { printf("Badness has occured! Did not read key file\n"); return 0; } else { printf("Opened the key file OK!\n"); } bufSize = RSA_public_encrypt(strlen(message), (unsigned char *) message, encrypted, rsa, RSA_PKCS1_PADDING); if (bufSize == -1) { printf("Badness has occured! encryption failed\n"); RSA_free(rsa); return 0; } else { printf("Encrypted the message OK! = \n%s\n", encrypted ); } if (RSA_private_decrypt(bufSize, encrypted, decrypted, rsa, RSA_PKCS1_PADDING) != -1) { printf("\nMessage decrypted to : %s\n", decrypted); } else { printf("Badness has occured! decryption failed\n"); RSA_free(rsa); return 0; } RSA_free(rsa); return 1; } Makefile文件
