[网络协议]Java中AES SHA1PRNG加密 C#对应加密

JAVA代码

import org.apache.tomcat.util.codec.binary.Base64;

import javax.crypto.Cipher;
import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;
import javax.crypto.spec.SecretKeySpec;
import java.net.URLEncoder;
import java.security.Key;
import java.security.SecureRandom;

public class EncryptUtil {
	
	public static String encryptAES(String data,String key) throws Exception {
        KeyGenerator kgen = KeyGenerator.getInstance("AES");
        SecureRandom secureRandom = SecureRandom.getInstance("SHA1PRNG");
        secureRandom.setSeed(key.getBytes());
        kgen.init(128, secureRandom);
        SecretKey skey = kgen.generateKey();
        byte[] raw = skey.getEncoded();
  
        SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
        Cipher cipher = Cipher.getInstance("AES");
        cipher.init(Cipher.ENCRYPT_MODE, skeySpec);
        byte[] encryptedData = cipher.doFinal(data.getBytes("UTF-8"));
        String hexStr = Base64.encodeBase64String(encryptedData);  
        return hexStr;
    }

    public static String decryptAES(String data,String key)throws Exception {
        KeyGenerator kgen = KeyGenerator.getInstance("AES");
        //kgen.init(128, new SecureRandom(key.getBytes()));
        SecureRandom secureRandom = SecureRandom.getInstance("SHA1PRNG");
        secureRandom.setSeed(key.getBytes());
        kgen.init(128, secureRandom);
        SecretKey skey = kgen.generateKey();
        byte[] raw = skey.getEncoded();
        SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
        Cipher cipher = Cipher.getInstance("AES");
        cipher.init(Cipher.DECRYPT_MODE, skeySpec);
        byte[] decryptedData = cipher.doFinal(Base64.decodeBase64(data));
        String respStr = new String(decryptedData,"UTF-8");
        return respStr;
    }

    public static void main(String[] args) throws Exception {
        String key="ABCDEFGABCDEFG";
        String username = "0001";
        String password = "0002";
        System.out.println(encryptAES(username, key));
        System.out.println(encryptAES(password, key));
    }
}

?0001 加密后?81Sd1kn/A2y+eshDtPLlqQ==

?0002 加密后?d3zRD2rsYLsXGl3U2LawNw==

需要对JAVA中的Key密钥进行编码生成一个字符串

public static void main(String[] args) throws NoSuchAlgorithmException {
        String encyKey="ABCDEFGABCDEFG";
        KeyGenerator kgen = KeyGenerator.getInstance("AES");
        java.security.SecureRandom random = java.security.SecureRandom.getInstance("SHA1PRNG");
        random.setSeed(encyKey.getBytes());
        kgen.init(128, random); 
        SecretKey secretKey = kgen.generateKey();
        byte[] enCodeFormat = secretKey.getEncoded();     
        System.out.println(Base64.encodeBase64String(enCodeFormat));
	}

拿着生成之后的 这段字符串到C#中进行加密 yfGIl68aDih3DamkzIJeYA==
?C#代码

public static string AESEncode(string encryptString, string encryptKey)
        {
            if (string.IsNullOrEmpty(encryptString)) return null;
            Byte[] toEncryptArray = Encoding.UTF8.GetBytes(encryptString);
            RijndaelManaged rm = new RijndaelManaged
            {
                Key = Convert.FromBase64String(encryptKey),
                Mode = CipherMode.ECB,
                Padding = PaddingMode.PKCS7
            };
            ICryptoTransform cTransform = rm.CreateEncryptor();
            Byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);
            return Convert.ToBase64String(resultArray, 0, resultArray.Length);
        }

调用 AESEncode("0001", "yfGIl68aDih3DamkzIJeYA==");

运行之后得到 81Sd1kn/A2y+eshDtPLlqQ==

这样和Java中的加密的一致
