我如何从java创建函数到objective-c
问题描述：
我是一个新鲜的IOS开发人员，面临加密和解密的问题。我如何从java创建函数到objective-c
解密代码（JAVA）
byte[] keyPass = pass.getBytes("ASCII");
byte[] aesIV = new byte[16];
byte[] Decryptdata = Base64.decode(encodedString, Base64.NO_WRAP);
System.arraycopy(Decryptdata, 0, aesIV, 0, 16);
byte[] data = new byte[Decryptdata.length - 16];
System.arraycopy(Decryptdata, 16, data, 0, dataToDecrypt.length - 16);
Key aesKey = new SecretKeySpec(keyPass, "AES");
IvParameterSpec ivSpec = new IvParameterSpec(aesIV);
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS7Padding");
cipher.init(Cipher.DECRYPT_MODE, aesKey, ivSpec);
Text = new String(cipher.doFinal(data), "UTF-8");
加密代码（JAVA）
byte[] keyPass = pass.getBytes("ASCII");
final Key key = new SecretKeySpec(keyPass, "AES");
final Cipher cipher = Cipher.getInstance("AES/CBC/PKCS7Padding");
byte[] byteMessage = text.getBytes("UTF-8");
cipher.init(Cipher.ENCRYPT_MODE, key);
byte[] cipherText = cipher.doFinal(byteMessage);
byte[] ivByte = cipher.getIV();
byte[] bytesTotal = new byte[ivByte.length+cipherText.length];
System.arraycopy(ivByte, 0, bytesTotal, 0, ivByte.length);
System.arraycopy(cipherText, 0, bytesTotal, ivByte.length, cipherText.length);
encyoted = Base64.encodeToString(bytesTotal, Base64.NO_WRAP);
如何创建加密和在Objective-C解密？
1.以十六进制形式提供加密数据，解密数据和IV。 2.使用全长密钥，AES支持128,192和256位密钥。我们会等你做你的工作，提供一个[mcve]。 – zaph
