Changes
|
||||
* Implement multi-part CCM API.
|
||||
The multi-part functions: mbedtls_ccm_starts(), mbedtls_ccm_set_lengths(),
|
||||
mbedtls_ccm_update_ad(), mbedtls_ccm_update(), mbedtls_ccm_finish()
|
||||
were introduced in mbedTLS 3.0 release, however their implementation was
|
||||
postponed until now.
|
||||
Implemented functions support chunked data input for both CCM and CCM*
|
||||
algorithms.

Bugfix
|
||||
* Fix missing constraints on x86_64 assembly code for bignum multiplication
|
||||
that broke some bignum operations with (at least) Clang 12.
|
||||
Fixes #4116, #4786, #4917.
