    <p>For iPhone I used <a href="https://github.com/Gurpartap/AESCrypt-ObjC" rel="nofollow">AESCrypt-ObjC</a>, and for Android use this code:</p> <pre><code>public class AESCrypt { private final Cipher cipher; private final SecretKeySpec key; private AlgorithmParameterSpec spec; public AESCrypt(String password) throws Exception { // hash password with SHA-256 and crop the output to 128-bit for key MessageDigest digest = MessageDigest.getInstance("SHA-256"); digest.update(password.getBytes("UTF-8")); byte[] keyBytes = new byte[32]; System.arraycopy(digest.digest(), 0, keyBytes, 0, keyBytes.length); cipher = Cipher.getInstance("AES/CBC/PKCS7Padding"); key = new SecretKeySpec(keyBytes, "AES"); spec = getIV(); } public AlgorithmParameterSpec getIV() { byte[] iv = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, }; IvParameterSpec ivParameterSpec; ivParameterSpec = new IvParameterSpec(iv); return ivParameterSpec; } public String encrypt(String plainText) throws Exception { cipher.init(Cipher.ENCRYPT_MODE, key, spec); byte[] encrypted = cipher.doFinal(plainText.getBytes("UTF-8")); String encryptedText = new String(Base64.encode(encrypted, Base64.DEFAULT), "UTF-8"); return encryptedText; } public String decrypt(String cryptedText) throws Exception { cipher.init(Cipher.DECRYPT_MODE, key, spec); byte[] bytes = Base64.decode(cryptedText, Base64.DEFAULT); byte[] decrypted = cipher.doFinal(bytes); String decryptedText = new String(decrypted, "UTF-8"); return decryptedText; } </code></pre> <p>}</p>
