使用RSA公钥验证签名 - VerifySignWithRsa ​

函数简介 ​

使用RSA公钥验证数据的签名。

接口名称 ​

VerifySignWithRsa

DLL调用 ​

c
int VerifySignWithRsa(long instance, string message, string signature, int shaType, int paddingType, string publicCer);

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。
message字符串要验证的明文。
signature字符串签名数据。
shaType整数型哈希类型：0-MD5；1-SHA1；2-SHA256；3-SHA384；4-SHA512；5-SHA3-256；6-SHA3-384；7-SHA3-512。
paddingType整数型填充类型：0-Pkcs1；1-Pss。
publicCer字符串RSA公钥。

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
std::string signature = ola.SignWithRsa("hello ola", privateKey, 2, 0);
int ok = ola.VerifySignWithRsa("hello ola", signature, 2, 0, publicKey);
csharp
using OLAPlug;

var ola = new OLAPlugServer();
string signature = ola.SignWithRsa("hello ola", privateKey, 2, 0);
int ok = ola.VerifySignWithRsa("hello ola", signature, 2, 0, publicKey);
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
signature = ola.SignWithRsa("hello ola", private_key, 2, 0)
ok = ola.VerifySignWithRsa("hello ola", signature, 2, 0, public_key)
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
ola.VerifySignWithRsa("hello ola", signature, 2, 0, publicKey);
cpp
var ola = com("OlaPlug.OlaSoft")
ola.VerifySignWithRsa("hello ola", signature, 2, 0, publicKey);
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
ola.VerifySignWithRsa("hello ola", signature, 2, 0, publicKey);

ola.VerifySignWithRsa("hello ola", signature, 2, 0, publicKey);
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
ola.VerifySignWithRsa("hello ola", signature, 2, 0, publicKey);
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
ola.VerifySignWithRsa("hello ola", signature, 2, 0, publicKey);
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
ola.VerifySignWithRsa("hello ola", signature, 2, 0, publicKey);

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
VerifySignWithRsa(instance, "hello ola", signature, 2, 0, publicKey);
csharp
using System.Runtime.InteropServices;

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long CreateCOLAPlugInterFace();
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int VerifySignWithRsa(long ola, string message, string signature, int shaType, int paddingType, string publicCer);

long instance = CreateCOLAPlugInterFace();
int ok = VerifySignWithRsa(instance, "hello ola", signature, 2, 0, publicKey);
python
long instance = CreateCOLAPlugInterFace();
VerifySignWithRsa(instance, "hello ola", signature, 2, 0, publicKey);
