将C＃加密代码转换为java [英] Convert C# encryption code to java

问题描述

我一直在尝试在java中进行解密，完全相同的解密在 C＃AES 256位带盐的加密库 [ ^ ]这是C＃。但我无法得到相同的输出，可以有人协助。



我尝试过：

I have been trying to do decryption in java for exact same decryption descibed in C# AES 256 bits Encryption Library with Salt[^] which is C# . But i am not able to get the same output , Could anybody assist.

What I have tried:

byte[] salt = new byte[] { 1, 2, 3, 4, 5, 6, 7, 8 };

			SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
			
			MessageDigest md = MessageDigest.getInstance("SHA-256" );
			
			md.update(KEY_IV.getBytes( StandardCharsets.UTF_8 ) );
			byte[] hashDigest = md.digest();
			
		
			String encryptedHashDigest = Base64.encodeBase64String(hashDigest);
			
			PBEKeySpec pbeKeySpec = new PBEKeySpec(encryptedHashDigest.toCharArray(),
					salt, 1000, 384);

			Key generatedKey = factory.generateSecret(pbeKeySpec);

			byte[] extractedKey = new byte[32];
			byte[] iv = new byte[16];


			System.arraycopy(generatedKey.getEncoded(), 0, extractedKey, 0, 32);
			System.arraycopy(generatedKey.getEncoded(), 32, iv, 0, 16);

			
			byte[] base64Decoded = Base64.decodeBase64(toBeDecrypted);

			Cipher c = Cipher.getInstance("AES/CBC/PKCS5Padding");

			c.init(2, new SecretKeySpec(extractedKey, "AES"), new IvParameterSpec(iv));

			byte[] decryptedBytes = c.doFinal(base64Decoded);

			System.out.println("Decrypted " + new String(Base64.encodeBase64(decryptedBytes), StandardCharsets.UTF_8));
