+Extra notes
+-----------
+
+For AES Counter mode (AES-CTR), the library supports two different sizes for Initialization
+Vector (IV):
+
+* 12 bytes: used mainly for IPSec, as it requires 12 bytes from the user, which internally
+  are appended the counter block (4 bytes), which is set to 1 for the first block
+  (no padding required from the user)
+
+* 16 bytes: when passing 16 bytes, the library will take them and use the last 4 bytes
+  as the initial counter block for the first block.
