@ -22,6 +22,12 @@ Features
MBEDTLS_CMAC_ALT). Submitted by Steve Cooreman, Silicon Labs.
* Add support for alternative implementations of GCM, selected by the
configuration flag MBEDTLS_GCM_ALT.
* Add support for alternative implementations for ECDSA, controlled by new
configuration flags MBEDTLS_ECDSA_SIGN_ALT, MBEDTLS_ECDSA_VERIFY_ALT and
MBEDTLS_ECDSDA_GENKEY_AT in config.h.
The following functions from the ECDSA module can be replaced
with alternative implementation:
mbedtls_ecdsa_sign(), mbedtls_ecdsa_verify() and mbedtls_ecdsa_genkey().
New deprecations
* Deprecate usage of RSA primitives with non-matching key-type
