* AES-based functions

AES: Extend key wrap design to support longer AES keys This adds kek_len argument to aes_wrap() and aes_unwrap() functions and allows AES to be initialized with 192 and 256 bit KEK in addition to the previously supported 128 bit KEK. The test vectors in test-aes.c are extended to cover all the test vectors from RFC 3394. Signed-off-by: Jouni Malinen <j@w1.fi>
2014-10-07 06:48:45 -04:00
* - AES Key Wrap Algorithm (RFC3394)
Extend AES-CMAC routines to support 256-bit keys omac1_aes_256() and omac1_aes_vector() can now be used to perform 256-bit CMAC operations similarly to the previously supported 128-bit cases. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
2015-01-23 09:59:33 -05:00
* - One-Key CBC MAC (OMAC1) hash with AES-128 and AES-256
Extend AES-SIV implementation to support different key lengths The previous implementation was hardcoded to use 128-bit AES key (AEAD_AES_SIV_CMAC_256). Extend this by allowing AEAD_AES_SIV_CMAC_384 and AEAD_AES_SIV_CMAC_512 with 192-bit and 256-bit AES keys. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>

2008-02-27 20:34:43 -05:00
* - 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>

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>
