1、安裝openssl
wget https://www.openssl.org/source/openssl-1.1.1b.tar.gz
./config --prefix=/usr/local/openssl --shared
--shared為添加動態庫，生成libssl.so，默認只有libssl.a靜態庫
make
make install
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
cp /usr/local/openssl/lib/openssl/libssl.so.1.1 /lib/x86_64-linux-gnu/
cp /usr/local/openssl/lib/openssl/libcrypto.so.1.1 /lib/x86_64-linux-gnu/
2、新建jni工程（eclipse為例）
新建java工程PemCheck
src下新建class com.jni.OpenSSLUtils.java
package com.jni;
public class OpenSSLUtils {
public native static int checkPem(String pem,String key);
}
cd ${workspace}/PemCheck
javah -classpath . -d . com.jni.OpenSSLUtils
javah -jni com.jni.OpenSSLUtils
此時src下生成com_jni_OpenSSLUtils.h頭檔案
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class com_jni_OpenSSLUtils */
#ifndef _Included_com_jni_OpenSSLUtils
#define _Included_com_jni_OpenSSLUtils
#ifdef __cplusplus
extern "C" {
#endif
/*
* Class: com_jni_OpenSSLUtils
* Method: checkPem
* Signature: (Ljava/lang/String;Ljava/lang/String;)I
*/
JNIEXPORT jint JNICALL Java_com_jni_OpenSSLUtils_checkPem
(JNIEnv *, jclass, jstring, jstring);
#ifdef __cplusplus
}
#endif
#endif
3、新建C++工程（eclipse為例）
new project >> C++ Project >> ShardLibrary
設定編譯環境
include jdk的頭檔案path
include jdk的頭檔案 linux path
include openssl 頭檔案path
編譯引數加上-fPIC
鏈接庫加上ssl,crypto
可以配置個命令將編譯后的so庫cp到測驗或使用的工程路徑下
4、撰寫openssl檢測代碼
新建src檔案夾，將com_jni_OpenSSLUtils.h復制到該目錄下，
同時新建com_jni_OpenSSLUtils.cpp
#include "com_jni_OpenSSLUtils.h"
#include "openssl/pem.h"
#include "openssl/bio.h"
#include "openssl/ssl.h"
#include <iostream>
using namespace std; // @suppress("Symbol is not resolved")
/*
* Class: com_jni_OpenSSLUtils
* Method: checkPem
* Signature: (Ljava/lang/String;Ljava/lang/String;)I
*/
JNIEXPORT jint JNICALL Java_com_jni_OpenSSLUtils_checkPem
(JNIEnv *env, jclass jc, jstring pem, jstring key){
BIO* keyBIO;
EVP_PKEY* pkey;
BIO* pemBIO = BIO_new_mem_buf(env->GetStringUTFChars(pem,0),-1);
X509* cert = PEM_read_bio_X509(pemBIO,NULL,NULL,NULL);
if (cert == NULL) {
cout << "PEM_read_bio_X509_AUX() failed" << endl;
if(NULL != pemBIO)
BIO_free(pemBIO);
return -1;
}
keyBIO = BIO_new_mem_buf(env->GetStringUTFChars(key,0),-1);
pkey = PEM_read_bio_PrivateKey(keyBIO,NULL,NULL,NULL);
if (pkey == NULL) {
cout << "PEM_read_bio_PrivateKey() failed" << endl;
if(NULL != cert)
X509_free(cert);
if(NULL != pemBIO)
BIO_free(pemBIO);
if(NULL != keyBIO)
BIO_free(keyBIO);
return -1;
}
SSL_library_init();
OpenSSL_add_all_algorithms();
SSL_load_error_strings();
SSL_CTX* ctx = SSL_CTX_new(SSLv23_client_method());
if (ctx == NULL) {
cout << "ctx create failed" << endl;
goto bad;
}
if(SSL_CTX_use_certificate(ctx,cert)<=0){
cout << "user certificate fail" << endl;
goto bad;
}
if(SSL_CTX_use_PrivateKey(ctx,pkey) <=0){
cout << "user key fail" << endl;
goto bad;
}
if(!SSL_CTX_check_private_key(ctx)){
cout << "key does not match the certificate" << endl;
goto bad;
}
if(NULL != pemBIO)
BIO_free(pemBIO);
if(NULL != keyBIO)
BIO_free(keyBIO);
if(NULL != pkey)
EVP_PKEY_free(pkey);
if(NULL != cert)
X509_free(cert);
if(NULL != ctx)
SSL_CTX_free(ctx);
return 0;
bad:
if(NULL != cert)
X509_free(cert);
if(NULL != pemBIO)
BIO_free(pemBIO);
if(NULL != keyBIO)
BIO_free(keyBIO);
if(NULL != pkey)
EVP_PKEY_free(pkey);
if(NULL != ctx)
SSL_CTX_free(ctx);
return -1;
}
Build All.
5、測驗
在java工程下新建Test 類
package com.jni;
public class Test {
static {
System.load("${solibpath}/libPemCheck.so");
}
public static void main(String[] args) {
System.out.println(
OpenSSLUtils.checkPem("-----BEGIN CERTIFICATE-----\n"
