 Android Encryption Example
 ========================
 
+This example encrypts the inputted string using AES, encrypts the key via RSA, and does the reverse when
+the decrypt button is clicked.
+
+We start by encrypting the plain text with AES
+
+```java
+byte[] iv = AESEncryptDecrypt.aesEncrypt(plainTextInputStream,
+                "secret key".toCharArray(),
+                "AES/ECB/PKCS5PADDING",
+                encOutputStream);
+```
+We then combine the outputted IV and the key we used:
+
+```java
+byte[] combined = Util.concat("secret key".getBytes(), iv);
+```
+
+Lastly we encryt the IV and key using an RSA public key:
+
+```java
+byte[] encryptedAESKeyIV = RSAEncryptDecrypt.encryptRSA(combined, rsaKey.getPublic());
+```
+

 This is an encryption example of RSA and AES (CBC, ECB, CTR) 256 bit key on android with unit tests. I have
