Answer 1

Try with below code it`s working for me.

AES Encryption

public static String getEncryptedString(String value) {
        try {
          byte[] key = your Key in byte array;
          byte[] input = sault in byte array

            return Base64.encodeToString(encrypt(value.getBytes("UTF-8"), key, input), Base64.DEFAULT);
        } catch (UnsupportedEncodingException e) {
            return "";
        }
    }


 public static byte[] encrypt(byte[] data, byte[] key, byte[] ivs) {
        try {
            Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
            SecretKeySpec secretKeySpec = new SecretKeySpec(key, "AES");
            byte[] finalIvs = new byte[16];
            int len = ivs.length > 16 ? 16 : ivs.length;
            System.arraycopy(ivs, 0, finalIvs, 0, len);
            IvParameterSpec ivps = new IvParameterSpec(finalIvs);
            cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec, ivps);
            return cipher.doFinal(data);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
