* AES-based functions
*
* - AES Key Wrap Algorithm (128-bit KEK) (RFC3394)
* - One-Key CBC MAC (OMAC1) hash with AES-128
* - AES-128 CTR mode encryption
* - AES-128 EAX mode encryption/decryption
* - AES-128 CBC
Add support for using 192-bit and 256-bit keys with AES-GCM This adds 192-bit and 256-bit key support to the internal AES implementation and extends the AES-GCM functions to accept key length to enable longer AES key use. Signed-hostap: Jouni Malinen <j@w1.fi>

* - AES-GCM
Move AES-CCM implementation into src/crypto This is a generic AES CCM implementation that can be used for other purposes than just implementing CCMP, so it fits better in a separate file in src/crypto. Signed-hostap: Jouni Malinen <j@w1.fi>

Add aes_gmac() as a wrapper for AES GMAC operations using GCM This is otherwise identical to aes_gcm_ae() but does not use the plain/crypt pointers since no data is encrypted. Signed-hostap: Jouni Malinen <j@w1.fi>
