- Resulted in a crash in the handshake stage when
used alongside TLS 1.3 (MBEDTLS_SSL_PROTO_TLS1_3)
- Fix build error when MBEDTLS_HARDWARE_SHA=n &&
MBEDTLS_DYNAMIC_BUFFER=y
- Fix build error when TLS 1.3 is enabled with
MBEDTLS_SSL_KEEP_PEER_CERTIFICATE=n
- Kconfig: Enabled MBEDTLS_HKDF_C by default when TLS 1.3 support is enabled
- esp-tls (mbedtls): Forced client to use TLS 1.3 when TLS 1.3 support is enabled
*MBEDTLS_ECDH_LEGACY_CONTEXT is now disabled by default.
*Fixed MBEDTLS_ECDH_LEGACY_CONTEXT issue for protocomm component.
*Removed all code under MBEDTLS_DEPRECATED_REMOVED
1) Fix build issue in mbedtls
2) skip the public headers check in IDF
3)Update Kconfig Macros
4)Remove deprecated config options
5) Update the sha API according to new nomenclature
6) Update mbedtls_rsa_init usage
7) Include mbedtls/build_info.h instead of mbedtls/config.h
8) Dont include check_config.h
9) Add additional error message in esp_blufi_api.h
- Removed code regarding MBEDTLS_DYNAMIC_FREE_PEER_CERT
(config was kept for backward compatibility)
- Combined mbedTLS v2.28.x related options under a separate Kconfig menu
Using these ciphers can constitute a security risk if the server
uses a weak prime for the key exchange.
Footprint impact:
Roughly 3K saved in text+rodata in default https_request example
This commit add following crypto changes
1. Update current crypto code with upstream supplicant code
2. Add a proper porting layer to use mbedtls APIs for all the crypto
operations used by supplicant.
Internal crypto will be used when USE_MBEDLTS flag is disabled
in supplicant's menuconfig.
This commit also removes the clutter in crypto files due to partial
porting of some APIs to mbedtls, all the code from those files have
been removed and rewritten in a generic way, this is inspired from
current upstream code.
This also reduces the lib size significantly, supplicant's lib
size reduces around ~567kb after this change(NB: lib size doesn't
indicate reduction in final bin size).
Add configuration option to fallback to software implementation
for exponential mod incase of hardware is not supporting it
for larger MPI value.
Usecase:
ESP32C3 only supports till RSA3072 in hardware. This config option
will help to support 4k certificates for WPA enterprise connection.
* Replaced crypotoauthlib with esp-cryptoauthlib
* Added menuconfig option for esp-tls about using HSM
* Added error codes for HSM in esp-tls,
* Added support to select different type of ATECC608A chips
* Added README, updated docs
* tcp_transport: Added option to enable secure_element for ssl
Closes https://github.com/espressif/esp-idf/issues/4432
* Add options to mbedtls for hardware acceleration
* Disable mbedtls EC curves if hardware acceleration is selected
since the hardware will have to define the curves supported
* Add a hardware ecdsa example
The GCM hardware accelerated algorithm for S2 would sometimes output
the wrong tag.
Added additional tests for AES and GCM
Re-enable HW GCM as default option
Adds the ESP certificate bundle feature that enables users to bundle a
root certificate bundle together with their application.
Default bundle includes all Mozilla root certificates
Closes IDF-296
Configurable option to use IRAM as byte accessible memory (in single core mode) using
load-store (non-word aligned and non-word size IRAM access specific) exception handlers.
This allows to use IRAM for use-cases where certain performance penalty
(upto 170 cpu cycles per load or store operation) is acceptable. Additional configuration
option has been provided to redirect mbedTLS specific in-out content length buffers to
IRAM (in single core mode), allows to save 20KB per TLS connection.
