common-secure

提供一些加密算法java代码封装 包括 RSA/AES/DES/3DES/MD5/SHA

代码封装了各类算法的加密解密。

1、SecureTest 测试了所有算法封装的代码

src\main\java\com\chenerzhu\common\example\SecureTest.java

2、SecureExample 列举了加密和解密的SecureUtils 使用

src\main\java\com\chenerzhu\common\util\SecureUtils.java
src\main\java\com\chenerzhu\common\example\SecureExample.java

3、SignatureExample 列举了SignatureUtils RSA签名的生成和验证

src\main\java\com\chenerzhu\common\util\SignatureUtils.java
src\main\java\com\chenerzhu\common\example\SignatureExample.java

MD5：

   String strMD5=SecureUtils.getMD5(INPUT_STR);  

SHA：

   String strSHA=SecureUtils.getSHA(INPUT_STR); 

DES：

 加密 String strDES=SecureUtils.encryptDES(INPUT_STR, key);
 解密 SecureUtils.decryptDES(strDES, key);

RSA：

 加密-解密：
 String strRSAPrivate = SecureUtils.encryptRSAPrivate(INPUT_STR, privateKeyString);//私钥加密
 String strRSAPublic = SecureUtils.encryptRSAPublic(INPUT_STR, publicKeyString);//公钥加密
 System.out.println("RSA 公钥解密:" + SecureUtils.decryptRSAPublic(strRSAPrivate, publicKeyString));
 System.out.println("RSA 私钥解密:" + SecureUtils.decryptRSAPrivate(strRSAPublic, privateKeyString));  
   
 签名-验证：
 String sign= SignatureUtils.getSignRSA(INPUT_STR,privateKeyString);
 System.out.println("签名："+sign+"\n length:"+sign.length());
 System.out.println("验证："+ SignatureUtils.verify(INPUT_STR,publicKeyString,sign));
