java..C#使用AES加密互解采用AES-128-ECB加密模式

原作者: [db:作者] 来自: [db:来源] 收藏 邀请
java需要下载外部包, commons codec.jar 1.6  較新的JAVA版本把Base64的方法改成靜態方法,可能會寫成
Base64.encodeToString(encrypted, 0);
import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
 
import org.apache.commons.codec.binary.Base64;
/**

public class AES {
 
    // 加密
    public static String Encrypt(String sSrc, String sKey) throws Exception {
        if (sKey == null) {
            System.out.print("Key为空null");
            return null;
        }
        // 判断Key是否为16位
        if (sKey.length() != 16) {
            System.out.print("Key长度不是16位");
            return null;
        }
        byte[] raw = sKey.getBytes("utf-8");
        SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
        Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");//"算法/模式/补码方式"
        cipher.init(Cipher.ENCRYPT_MODE, skeySpec);
        byte[] encrypted = cipher.doFinal(sSrc.getBytes("utf-8"));
 
        return new Base64().encodeToString(encrypted);//此处使用BASE64做转码功能,同时能起到2次加密的作用。
    }
 
    // 解密

        try {
            // 判断Key是否正确
