AES加密简化版本 - AESEncrypt ​

函数简介 ​

AES加密简化版本，使用默认参数（CBC模式和PKCS7填充，默认IV为0）。

接口名称 ​

AESEncrypt

DLL调用 ​

c
long AESEncrypt(long instance, string source, string key);

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。
source字符串源数据。
key字符串密钥，字符串长度应为16/24/32个字符，对应AES-128/192/256。

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
std::string cipher = ola.AESEncrypt("hello ola", "1234567890123456");
std::string plain = ola.AESDecrypt(cipher, "1234567890123456");
csharp
using OLAPlug;

var ola = new OLAPlugServer();
string cipher = ola.AESEncrypt("hello ola", "1234567890123456");
string plain = ola.AESDecrypt(cipher, "1234567890123456");
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
cipher = ola.AESEncrypt("hello ola", "1234567890123456")
plain = ola.AESDecrypt(cipher, "1234567890123456")
java

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
long ptr = AESEncrypt(instance, "hello ola", "1234567890123456");
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)]

long instance = CreateCOLAPlugInterFace();
long ptr = AESEncrypt(instance, "hello ola", "1234567890123456");
if (ptr != 0) {
    StringBuilder sb = new StringBuilder(GetStringSize(ptr) + 1);
    GetStringFromPtr(ptr, sb, sb.Capacity);
    FreeStringPtr(ptr);
    string cipher = 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.AESEncrypt(instance, b"hello ola", b"1234567890123456")

返回值 ​

返回值说明
非 0成功，返回 加密后的数据的字符串指针。
0失败。

注意事项 ​

项目说明
此接口使用CBC模式和PKCS7填充此接口使用CBC模式和PKCS7填充，默认IV为0。如需自定义参数请使用 AESEncryptEx。
