转换RSA私钥 - ConvertRSAPrivateKey ​

函数简介 ​

将RSA私钥从一种格式转换为另一种格式。

接口名称 ​

ConvertRSAPrivateKey

DLL调用 ​

c
long ConvertRSAPrivateKey(long instance, string privateKey, int inputType, int outputType);

参数说明 ​

参数名类型说明
instance长整数型OLAPlug对象的指针，由 CreateCOLAPlugInterFace 接口生成。
privateKey字符串要转换的私钥。
inputType整数型输入类型：0-pem格式；1-xml格式；2-PKCS1格式。
outputType整数型输出类型：0-pem格式；1-xml格式；2-PKCS1格式。

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
// privateKey 为 PEM/XML/PKCS1 格式私钥字符串
std::string converted = ola.ConvertRSAPrivateKey(privateKey, 0, 0);
csharp
using OLAPlug;

var ola = new OLAPlugServer();
string converted = ola.ConvertRSAPrivateKey(privateKey, 0, 0);
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
converted = ola.ConvertRSAPrivateKey(private_key, 0, 0)
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
ola.ConvertRSAPrivateKey(privateKey, 0, 0);
cpp
var ola = com("OlaPlug.OlaSoft")
ola.ConvertRSAPrivateKey(privateKey, 0, 0);
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
ola.ConvertRSAPrivateKey(privateKey, 0, 0);
text
.局部变量 ola, OLAPlug
ola.创建 ()
ola.ConvertRSAPrivateKey(privateKey, 0, 0);
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
ola.ConvertRSAPrivateKey(privateKey, 0, 0);
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
ola.ConvertRSAPrivateKey(privateKey, 0, 0);
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
ola.ConvertRSAPrivateKey(privateKey, 0, 0);

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
long ptr = ConvertRSAPrivateKey(instance, privateKey, 0, 0);
if (ptr != 0) {
    char buffer[4096] = {0};
    GetStringFromPtr(ptr, buffer, sizeof(buffer));
    FreeStringPtr(ptr);
}
csharp
using System.Runtime.InteropServices;
using System.Text;

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int GetStringFromPtr(long ptr, StringBuilder lpString, int size);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int FreeStringPtr(long ptr);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long CreateCOLAPlugInterFace();
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long ConvertRSAPrivateKey(long ola, string privateKey, int inputType, int outputType);

long instance = CreateCOLAPlugInterFace();
long ptr = ConvertRSAPrivateKey(instance, privateKey, 0, 0);
if (ptr != 0) {
    StringBuilder sb = new StringBuilder(GetStringSize(ptr) + 1);
    GetStringFromPtr(ptr, sb, sb.Capacity);
    FreeStringPtr(ptr);
    string converted = sb.ToString();
}
python
from ctypes import CDLL, c_int, c_int64

ola = CDLL("OLAPlug_x64.dll")
ola.CreateCOLAPlugInterFace.restype = c_int64
instance = ola.CreateCOLAPlugInterFace()
ptr = ola.ConvertRSAPrivateKey(instance, private_key, 0, 0)
