+A pure-Python implementation of the AES block cipher algorithm and the common modes of operation (CBC, CFB, CTR, ECB and OFB).
 
 
 Features
 --------
 
 * Supports all AES key sizes
 * Supports all AES common modes
-* Pure-Python (no external dependancies)
+* Pure-Python (no external dependencies)
 * BlockFeeder API allows streams to easily be encrypted and decrypted
 * Python 2.x and 3.x support (make sure you pass in bytes(), not strings for Python 3)

 ### Common Modes of Operation
 
-There are many modes of operations, each with various pros and cons. In general though, the **CBC** and **CTR** modes are recommended. The **ECB is NOT recommended.**, and is included primarilty for completeness.
