MD5加密(JAVA FUNCTION &ORACLE DB FUNCTION)

JAVA:

	public static String encodeMD5(String s) {
		if (s == null) {
			return null;
		}
		return DigestUtils.md5Hex(s);
	}

oracle:

create or replace function MD5_Digest (
vin_string IN VARCHAR2
) RETURN VARCHAR2 IS
--
-- Return an MD5 hash of the input string.
--
BEGIN
RETURN Lower(Dbms_Obfuscation_Toolkit.Md5 ( input => utl_raw.cast_to_raw(vin_string)));
END MD5_Digest;

提供一个可以直接使用的java class:

package com;

import org.apache.commons.codec.digest.DigestUtils;

public final class MD5Encrypt {

	private static final ThreadLocal<MD5Encrypt> local = new ThreadLocal<MD5Encrypt>();

	private MD5Encrypt() {
		super();
	}

	public static MD5Encrypt getEncrypt() {
		MD5Encrypt encrypt = local.get();
		if (encrypt == null) {
			encrypt = new MD5Encrypt();
			local.set(encrypt);
		}
		return encrypt;
	}

	public static String encodeMD5(String s) {
		if (s == null) {
			return null;
		}
		return DigestUtils.md5Hex(s);
	}
	
	public static String encodeSHA(String s) {
		if (s == null) {
			return null;
		}
		return DigestUtils.shaHex(s);
	}
	
	public static void main(String arg[]){
		System.out.println("MD5: " + MD5Encrypt.getEncrypt().encodeMD5("11111"));
	}
}
