java加密的几种方式
基本的单向加密算法:BASE 严格地说,属于编码格式,而非加密算法
MD5(Message Digest algorithm 5,work clock源码信息摘要算法)
SHA(Secure Hash Algorithm,安全散列算法)
HMAC(Hash Message Authentication Code,游戏内部充值源码解锁散列消息鉴别码)
复杂的编程猫推箱子源码对称加密(DES、PBE)、非对称加密算法:
DES(Data Encryption Standard,数据加密算法)
PBE(Password-based encryption,基于密码验证)
RSA(算法的名字以发明者的名字命名:Ron Rivest, AdiShamir 和Leonard Adleman)
DH(Diffie-Hellman算法,密钥一致协议)
DSA(Digital Signature Algorithm,数字签名)
ECC(Elliptic Curves Cryptography,椭圆曲线密码编码学)
代码参考:
/**
* BASE加密
*
* @param key
* @return
* @throws Exception
*/
public static String encryptBASE(byte[] key) throws Exception {
return (new BASEEncoder()).encodeBuffer(key);
}
/**
* MD5加密
*
* @param data
* @return
* @throws Exception
*/
public static byte[] encryptMD5(byte[] data) throws Exception {
MessageDigest md5 = MessageDigest.getInstance(KEY_MD5);
md5.update(data);
return md5.digest();
}
/**
* SHA加密
*
* @param data
* @return
* @throws Exception
*/
public static byte[] encryptSHA(byte[] data) throws Exception {
MessageDigest sha = MessageDigest.getInstance(KEY_SHA);
sha.update(data);
return sha.digest();
}
}
/**
* 初始化HMAC密钥
*
* @return
* @throws Exception
*/
public static String initMacKey() throws Exception {
KeyGenerator keyGenerator = KeyGenerator.getInstance(KEY_MAC);
SecretKey secretKey = keyGenerator.generateKey();
return encryptBASE(secretKey.getEncoded());
}
/**
* HMAC加密
*
* @param data
* @param key
* @return
* @throws Exception
*/
public static byte[] encryptHMAC(byte[] data,源码的十六进制 String key) throws Exception {
SecretKey secretKey = new SecretKeySpec(decryptBASE(key), KEY_MAC);
Mac mac = Mac.getInstance(secretKey.getAlgorithm());
mac.init(secretKey);
return mac.doFinal(data);
}
Java中用Base编程的文件批量加密解密工具程序代码
/** * BASE解密 * * @param key * @return * @throws Exception */
public static byte[] decryptBASE(String key) throws Exception { return (new BASEDecoder()).decodeBuffer(key); } /** * BASE加密 * * @param key * @return * @throws Exception */ public static String encryptBASE(byte[] key) throws Exception { return (new BASEEncoder()).encodeBuffer(key); }
这个(base编码)音频数据怎么用?

import java.io.InputStream;

import sun.misc.BASEDecoder;
import sun.misc.BASEEncoder;
public class base {
public static String getWAVString(){
File fi = new File("click.wav");
if (!fi.exists())
return "";
byte[] data = null;
try{
InputStream is = new FileInputStream(fi);
data = new byte[is.available()];
is.read(data);
is.close();
}catch(Exception ex){
ex.printStackTrace();
}
BASEEncoder encoder = new BASEEncoder();
return encoder.encode(data);
}
public static void getWAV(){
BASEDecoder decoder = new BASEDecoder();
try{
byte[] data = decoder.decodeBuffer(WAVString);
/*for(int i=0 ;i<data.length;i++){
if (data[i] < 0) {
data[i] += ;
}
}*/
OutputStream out = new FileOutputStream("click_BASE.wav");
out.write(data);
out.flush();
out.close();
}catch(Exception ex){
}
}
public static void main(String[] args){
WAVString = getWAVString();
try{
FileWriter out = new FileWriter("Click_BASEString.txt");
out.write(WAVString);
out.flush();
out.close();
}catch(Exception ex){
}
getWAV();
}
private static String WAVString;
}
java base解码 怎么是乱码呢
会乱码的原因是你的编码不一致导致的php中的urlencode的编码是和系统编码一致的(比如windows默认gb,ubuntu默认utf-8)
所以首先需要确定你的系统编码,之后根据得到的系统编码在调用java的decode方法的时候,将这个编码传入(考虑到你的例子中有繁体字,所以,建议你使用utf-8编码),以下是我使用utf-8编码的例子(php环境是ubuntun下)
