### 24-October-2023 ###
+ Align function prototype and implementation :
- ssl_calc_verify_tls
- ssl_calc_verify_tls_sha256
- ssl_calc_verify_tls_sha384
+ Increase padbuf size in ssl_calc_finished_tls_sha384 for sha512 use
### 24-July-2023 ###
+Improve mbedtls_hardware_poll :
- Set return error value to mbedtls error value.
- Replace memset function by loop function to avoid data corruption during memory copy.
+ Use variable ret in mbedtls_pk_parse_key function to avoid IAR warning.
### 25-August-2020 ###
========================
+ Update GCM templates with Additional data not 4 bytes aligned
(default configuration enabled by define : STM32_AAD_ANY_LENGTH_SUPPORT)
### 02-April-2020 ###
========================
+ Add in template directory the files :
- Update aes_alt_template.[c/h]
- gcm_alt_template.[c/h] : mbed TLS GCM Hw crypto using HAL/CRYP API
- ccm_alt_template.[c/h] : mbed TLS CCM Hw crypto using HAL/CRYP API
- cryp_stm32.[c/h] : ST file with commom procedures on crypto processor
- sha1_alt_template.[c/h] : mbed TLS Sha1 Hw crypto using HAL/CRYP API
- sha256_alt_template.[c/h] : mbed TLS Sha256 Hw crypto using HAL/CRYP API
- md5_alt_template.[c/h] : mbed TLS MD5 Hw crypto using HAL/CRYP API
- hash_stm32.[c/h] : ST file with commom procedures on hash processor
+ Fix GCM selftest by skipping tests with IV out of the values supported by HW.
Hw implementation limit IV to a length of 96-bits.
It is the value recommended for situations in which efficiency is critical.
### 17-Jan-2020 ###
========================
+ Add in template directory the files :
- aes_alt_template.[c/h] : mbed TLS AES Hw crypto using HAL/CRYP API
### 10-Dec-2019 ###
========================
+ Upgrade to use mbedTLS V2.16.2
### 21-Dec-2018 ###
========================
+ Upgrade to use mbedTLS V2.14.1
+ Fix Keil compiler warning
+ Update timing_alt_template.c : Protect the mbedtls alternate timing APIs with the flag MBEDTLS_TIMING_ALT
### 06-July-2018 ###
========================
+ Upgrade to use mbedTLS V2.11.0
+ Re-apply the fix for EWARM warnings due to invalid code for 32 bit machines
(still not integrated see https://github.com/ARMmbed/mbedtls/issues/683)
+ add template directory containing the files:
- net_socket_template.c : mbedtls networking routines implemented using LwIP API
- rng_alt_template.c : mbedtls RNG routing using the HAL_RNG API
- threading_alt_template.[c/h] : mbedtls mutex management template implementation
using the CMSIS-RTOS v1/v2 API
- timing_alt.[c/h] : mbedTLS alternate timing API based on
CMSIS-RTOS v1/v2 API
### 10-November-2017 ###
========================
+ Upgrade to use mbedTLS V2.6.1
+ fix missing prototype error,in the library/aes.c file, with EWARM toolchain when MBEDTLS_DEPRECATED_REMOVED is defined.
### 09-October-2017 ###
========================
+ Upgrade to use mbedTLS V2.6.0
+ Update the "net_socket_template.c" file to use LwIP API, this make it directly usable in the applications
+ Fix compiler warnings by including newer patches from the mbedTLS git tree
### 23-December-2016 ###
========================
+ Upgrade to use mbedTLS V2.4.0
+ Rename the "net_sockets.c" to "net_sockets_template.c" to provide the net_sockets.c actual implementation in user projects.
+ Fix warnings due to invalid code for 32 bit machines, see https://github.com/ARMmbed/mbedtls/issues/683
### 27-March-2015 ###
=====================
+ Add support of the hardware Cryptographic and Hash processors embedded in STM32F756xx devices.
This support is activated by defining "USE_STM32F7XX_HW_CRYPTO" macro in PolarSSL config.h file.
+ Fix some compilation warnings
### 13-March-2015 ###
=====================
+ Align to latest version of STM32Cube CRYP HAL driver: add initialization of Crypto handler's Instance field
### 18-February-2014 ###
========================
+ PolarSSL V1.2.8 customized version for STM32Cube solution.
+ Source files modified to support the hardware Cryptographic and Hash processors embedded in
STM32F415xx/417xx/437xx/439xx devices. This support is activated by defining
"USE_STM32F4XX_HW_CRYPTO" macro in PolarSSL config.h file.
