MD5加密示例

Java 加密方法

import java.io.UnsupportedEncodingException;
import java.security.MessageDigest;
public class MD5Utils  {
    /***
     * MD5加码 生成32位md5码
     */
    public static String string2MD5(String inStr) {
        MessageDigest md5 = null;
        try{
            md5 = MessageDigest.getInstance("MD5");
        }catch (Exception e){
            System.out.println(e.toString());
            e.printStackTrace();
            return "";
        }
        byte[] byteArray = new byte[0];
        try {
            byteArray = inStr.getBytes("UTF-8");
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        byte[] md5Bytes = 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();
    }
}

C#加密方法

public string CreateSign(string sign)
{
    var md5 = MD5.Create();
    var bytes = md5.ComputeHash(Encoding.UTF8.GetBytes(sign));
    var result = new StringBuilder();
    foreach (var b in bytes)
    {
        var hex = b.ToString("x2");
        result.Append(hex);
    }
    return result.ToString();
}
