要求在.Net端生成公钥私钥对。
然后在.Net端使用RSA公钥加密;在Linux端使用RSA私钥解密。
最初的尝试是:.Net端使用RSACryptoServiceProvider; linux端使用OpenSSL
搞了整整5个小时,有木有啊,有木有啊! .Net的RSA和OpenSSL对不上,有木有啊,有木有啊!
人都搞晕了就是对不上。最后解决方式换成了,.Net端使用 OpenSSL.NET.
.Net端代码
- string publicKeyFile = context.Server.MapPath("~/App_Data/public.pem");
- using( RSA rsa = RSA.FromPublicKey(BIO.File(publicKeyFile, "r")) )
- {
- buffer = rsa.PublicEncrypt( buffer, RSA.Padding.OAEP);
- encryptedKey = Convert.ToBase64String(buffer);
- }
Linux端代码
- BIO *b64, *bmem;
- // Base64解码
- unsigned char *buffer = (unsigned char *)malloc(length);
- memset(buffer, 0, length);
- b64 = BIO_new(BIO_f_base64());
- BIO_set_flags(b64, BIO_FLAGS_BASE64_NO_NL);
- bmem = BIO_new_mem_buf(szKey, length);
- bmem = BIO_push(b64, bmem);
- int len = BIO_read(bmem, buffer, length);
- BIO_free_all(bmem);
- // 加载私钥
- BIO * key = NULL;
- RSA * r = NULL;
- key = BIO_new(BIO_s_file());
- BIO_read_filename(key, "/val/XXX/private.pem" );
- r = PEM_read_bio_RSAPrivateKey(key, NULL, NULL, NULL);
- BIO_free_all(key);
- unsigned char * plainText = (unsigned char *)malloc(len);
- memset( plainText, 0, len);
- // 解密
- int ret = RSA_private_decrypt( RSA_size(r), buffer, plainText, r, RSA_PKCS1_OAEP_PADDING);
- RSA_free(r);
- free(plainText);
- free(buffer);
