javaMD5加密类

大家好，又见面了，我是你们的朋友全栈君。

import java.security.MessageDigest;

public class MyMD5 { private String inStr; private MessageDigest md5;

public MyMD5 (String inStr) { this.inStr = inStr; try { this.md5 = MessageDigest.getInstance(“MD5”); } catch (Exception e){ System.out.println(e.toString()); e.printStackTrace(); } }

public String compute() { char[] charArray = this.inStr.toCharArray(); byte[] byteArray = new byte[charArray.length];

for (int i=0; i<charArray.length; i++) { byteArray[i] = (byte) charArray[i]; }

byte[] md5Bytes = this.md5.digest(byteArray); StringBuffer hexValue = new StringBuffer();

for (int i = 0; i < md5Bytes.length; i++) { int val = ((int) md5Bytes[i]) & 0xff; if (val < 16) { hexValue.append(“0”); } hexValue.append(Integer.toHexString(val)); } return hexValue.toString(); }

public static void main(String[] args) { MyMD5 md5s=new MyMD5(“abc”); String postString = md5s.compute(); System.out.println(postString); if(postString.equals(“900150983cd24fb0d6963f7d28e17f72”)){ System.out.println(“true”); } else { System.out.println(“false”); } }

}
