跪求md5算法的可执行程序，最好带上流程图和源代码，谢了～

1 Java版MD5
MD5Utiljava
[java] view plain copy
package comcncounterutilcommon;

import javasecurityMessageDigest;
import javasecurityNoSuchAlgorithmException;

/
Java消息摘要算法 MD5 工具类,其实其他摘要算法的实现也类似
/
public class MD5Util {
/
对文本执行 md5 摘要加密, 此算法与 mysql,JavaScript生成的md5摘要进行过一致性对比
@param plainText
@return 返回值中的字母为小写
/
public static String md5(String plainText) {
if (null == plainText) {
plainText = "";
}
String MD5Str = "";
try {
// JDK 6 支持以下6种消息摘要算法，不区分大小写
// md5,sha(sha-1),md2,sha-256,sha-384,sha-512
MessageDigest md = MessageDigestgetInstance("MD5");
mdupdate(plainTextgetBytes());
byte b[] = mddigest();

int i;

StringBuilder builder = new StringBuilder(32);
for (int offset = 0; offset < blength; offset++) {
i = b[offset];
if (i < 0)
i += 256;
if (i < 16)
builderappend("0");
builderappend(IntegertoHexString(i));
}
MD5Str = buildertoString();
// LogUtilprintln("result: " + buftoString());// 32位的加密
} catch (NoSuchAlgorithmException e) {
eprintStackTrace();
}
return MD5Str;
}
// 一个简版测试
public static void main(String[] args) {
String m1 = md5("1");
String m2 = md5(m1);
/ 输出为
m1=c4ca4238a0b923820dcc509a6f75849b
m2=28c8edde3d61a0411511d3b1866f0636
/
Systemoutprintln("m1="+m1);
Systemoutprintln("m2="+m2);
}
}
2 MySQL版MD5
MySQL直接支持 md5函数调用
[sql] view plain copy
select md5('1') as m1, md5(md5('1')) as m2;
执行结果为:
[plain] view plain copy
MariaDB [(none)]> select md5('1') as m1, md5(md5('1')) as m2;
+----------------------------------+----------------------------------+
| m1 | m2 |
+----------------------------------+----------------------------------+
| c4ca4238a0b923820dcc509a6f75849b | 28c8edde3d61a0411511d3b1866f0636 |
+----------------------------------+----------------------------------+
1 row in set (000 sec)
3 JavaScript 版MD5函数
md5js 代码如下:
[javascript] view plain copy
/! JavaScript 的 MD5 实现 /

// 括号表达式, (xxxxx) 是用来将内部的语句、表达式的结果作为一个结果
// 常见的是将json字符串用 eval 解析时,需要 eval("(" +jsonstr+ ")");
// () 内部定义了一个空间, 里面定义的变量不会污染到全局空间,很适合做lib
// (function UMD(对象/函数名name, 上下文this, 函数/对象的定义)) 返回一个匿名函数
// 因为第一个括号内 的结果是一个函数,而函数可以这样调用: (function(形参){})(实参);
// 这种匿名函数被浏览器解析后会自动执行一次
(function UMD(name, context, definition) {
if ( typeof module !== "undefined" && moduleexports) {
// 如果 module 存在,并且moduleexports存在,则将赋值结果赋给 它
// 可以不用管
moduleexports = definition();
} else if ( typeof define === "function" && defineamd) {
// 如果 define 这个函数存在,应该是另一个基础类库，则使用define
// 可以不用管
define(definition);
} else {
// 简单一点,可以看成: 调用传入的definition函数，将返回的对象绑定到全局空间
// 当然,根据传入的上下文不同,也可以绑定到其他对象下面,成为一个属性方法
context[name] = definition(name, context);
}
}
)("md5", this, function DEF(name, context) {"use strict";
// 上面的 use strict 表示严格语法模式,有错误就拒绝执行
// 而普通的JS,是解释执行,不执行的地方,有些错误也不影响其他代码的执行
// 作为类库,使用严格模式是很有必要的严格模式声明必须放到一个namespace空间的最起始处

//
var old_public_api = (context || {})[name];
// 最后要返回的对象/函数
function md5_func(text) {
return hex_md5(text);
};
// 下面一堆是具体的算法 可以先不用管
