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));
