f20b5daf39 Use XMEM_NEQ instead of mem_neq 
mem_neq is no more used directly. XMEM_NEQ is used instead,
in the same way XMEMCMP, XMEMCPY,... are.

46c038f7d4 adapt rsa_test() to modified pkcs#1 decoding routines 2014-11-13 22:30:07 +01:00
Steffen Jaeckel
1e9e98aa0d make pkcs#1 decode functions constant-time 
as proposed in RFC 3447 only one error return code is used when there are
errors while decoding the pkcs#1 format.
also, all steps are executed and only the "output" is skipped if something
went wrong.

Sorry this could break backwards compatibility, since there's no more
BUFFER_OVERFLOW messaging.
Former error-handling code could also be affected because now there's only
OK as return code in cases where "res" is also set to '1'.

992506cb49 Add incremental CCM authentication processing 
CCM is only meant for packet mode where the length of the input is known in
advance. Since it is a packet mode function, CCM only had one function that
performs the protocol.

However, incremental authentication is usefull in some usecases. It also
ensure some kind of coherencies when processing with a given authentication
mode or another. To achieve this aim, this commit adds the following functions:
    ccm_init()
    ccm_add_aad()
    cm_add_nonce()
    ccm_process()
    ccm_done()
    ccm_reset()
as well as the data structure
    ccm_state

you can define "LTC_DER_TESTS_PRINT_FLEXI" at compile time to print
the decoded cert whenn running the test executable...
well not all of it, since some parts of the cert are marked as
"context-specific" so we would need to do some further digging
...these are the parts that are output as "EOL"...

Pascal Brand
adc54d08d0 Enable multiple XTS encryption or decryption 
multiple xts_encrypt() cannot be performed because the
tweak is not updated. That means that
  xts_encrypt(buffer1, tweak)
  xts_encrypt(buffer2, tweak)
is not the same as
  xts_encrypt(concat(buffer1, buffer2), tweak)

Current patch enables such functionalities by
updating the tweak as output of the encryption.
Note that the tweak is no more constant.

The very same modification is performed
on xts_decrypt()
