JAVA 对应的 AES 加密 与 解密

[jovien]

public static void commonEncryptDecrypt(String pwd) throws UnsupportedEncodingException, NoSuchAlgorithmException, NoSuchPaddingException {
				ivParameterSpec = new IvParameterSpec(SECRET_KEY.getBytes("UTF-8"));
				secretKeySpec = new SecretKeySpec(pwd.getBytes("UTF-8"), "AES");
				cipher = Cipher.getInstance("AES/CBC/PKCS5PADDING");
	}


//加密
public static String encrypt(String toBeEncrypt,String pwd) throws InvalidKeyException, InvalidAlgorithmParameterException, IllegalBlockSizeException, BadPaddingException, UnsupportedEncodingException, NoSuchAlgorithmException, NoSuchPaddingException{
		commonEncryptDecrypt(pwd);
			
				
			cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec, ivParameterSpec);
			byte[] encrypted = cipher.doFinal(toBeEncrypt.getBytes());
	    return Base64.getEncoder().encodeToString(Base64.getEncoder().encode(encrypted));
	}


//解密
public static String decrypt(String encrypted,String pwd) throws InvalidKeyException, InvalidAlgorithmParameterException, IllegalBlockSizeException, BadPaddingException, UnsupportedEncodingException, NoSuchAlgorithmException, NoSuchPaddingException {
			commonEncryptDecrypt(pwd);
			cipher.init(Cipher.DECRYPT_MODE, secretKeySpec, ivParameterSpec);
			byte[] baseStr = Base64.getDecoder().decode(encrypted);
			byte[] decryptedBytes = cipher.doFinal(Base64.getDecoder().decode(baseStr));
		
	    return new String(decryptedBytes);
	}

求大神们写一个对应的C#版本的加密与揭秘方法！！！！！！！！！！！！

希望大神帮助一下。。。

高人都没时间来指导一下吗？

自己对照着修改一下。

JAVA 中 还有一段忘记贴出来了，采用的是CBC模式，增加了向量 private static final String SECRET_KEY = "2cc8325f45829ed1"; private static IvParameterSpec ivParameterSpec; private static SecretKeySpec secretKeySpec; private static Cipher cipher;
