使用Apache digest做md5加密的范例

活用Apache commons，使用Apache digest做md5加密的范例。

import java.security.NoSuchAlgorithmException;import org.apache.commons.codec.digest.DigestUtils;/** * @author loveapple * @since 2009-01-15 * @version $Revision$ */public class MD5Test { //加密后的文字串static final String CHANGEME_MD5_STR = "4cb9c8a8048fd02294477fcb1a41191a";//被加密的文字串static final String TARGET = "changeme";public static void main(String[] argvs){try {MessageDigestAdapter adapter = new MessageDigestAdapter("MD5");String md5str = adapter.digest(TARGET);System.out.println(md5str);if(CHANGEME_MD5_STR.equals(md5str)){System.out.println(md5str + "->" + CHANGEME_MD5_STR);System.out.println("same with mysql request. length is [" + md5str.length() + "]");}else{System.out.println("NOT SAME! with mysql requse");}System.out.println("common codec result: " + DigestUtils.md5Hex(TARGET));if(CHANGEME_MD5_STR.equals(DigestUtils.md5Hex(TARGET))){System.out.println("code result same with mysql request too. length is [" + DigestUtils.md5Hex(TARGET) + "]");}}catch (NoSuchAlgorithmException e) {e.printStackTrace();}}}
