c653990ed5 cipher: Add wrappers for AES-XTS
AES-XTS does not support multipart use as it can only operate on an entire
sector at a time.

8c0fd1e881 Add cipher abstraction and test cases for OFB block mode
Adds OFB as additional block mode in the cipher abstraction, and additional
test cases for that block mode.

3dc62a0a9b chachapoly: force correct mode for integrated API
Allowing DECRYPT with crypt_and_tag is a risk as people might fail to check
the tag correctly (or at all). So force them to use auth_decrypt() instead.

32902e6eae cipher: handle ChaCha20 as a stream cipher
That's what it is. So we shouldn't set a block size != 1.

While at it, move call to chachapoly_update() closer to the one for GCM, as
they are similar (AEAD).

5ef92d309a chachapoly: adjust parameter order
This module used (len, pointer) while (pointer, len) is more common in the
rest of the library, in particular it's what's used in the GCM API that
very comparable to it, so switch to (pointer, len) for consistency.

Note that the crypt_and_tag() and auth_decrypt() functions were already using
the same convention as GCM, so this also increases intra-module consistency.

fe725defae cipher: use new functions from chachapoly 2018-05-24 13:37:31 +02:00

dca3a5d884 Rename aead_chacha20_poly1305 to chachapoly
While the old name is explicit and aligned with the RFC, it's also very long,
so with the mbedtls_ prefix prepended we get a 31-char prefix to each
identifier, which quickly conflicts with our 80-column policy.

The new name is shorter, it's what a lot of people use when speaking about
that construction anyway, and hopefully should not introduce confusion at
it seems unlikely that variants other than 20/1305 be standardised in the
foreseeable future.

16b04ce641 Fix unused function warning under certain configurations.
I refactored some code into the function mbedtls_constant_time_memcmp
in commit 7aad291 but this function is only used by GCM and
AEAD_ChaCha20_Poly1305 to check the tags. So this function is now
only enabled if either of these two ciphers is enabled.

e32df087fb Remove individual copies of mbedtls_zeroize()
This commit removes all the static occurrencies of the function
mbedtls_zeroize() in each of the individual .c modules. Instead the
function has been moved to utils.h that is included in each of the
modules.

6a54336897 Fix integer overflows in buffer bound checks
Fix potential integer overflows in the following functions:
  * mbedtls_md2_update() to be bypassed and cause
  * mbedtls_cipher_update()
  * mbedtls_ctr_drbg_reseed()
This overflows would mainly be exploitable in 32-bit systems and could
cause buffer bound checks to be bypassed.

327398ad3a Refactor and change CMAC interface
Change the CMAC interface to match the mbedtls_md_hmac_xxxx() interface. This
changes the overall design of the CMAC interface to make it more consistent with
the existing HMAC interface, and will allow incremental updates of input data
rather than requiring all data to be presented at once, which is what the
current interface requires.
