Before, if an application + passed keys that belonged to different group, the first key's data was + interpreted according to the second group, which could lead to either + an error or a meaningless output from mbedtls_ecdh_get_params. In the + latter case, this could expose at most 5 bits of the private key. + Bugfix * Fix a compilation issue with mbedtls_ecp_restart_ctx not being defined when MBEDTLS_ECP_ALT is defined. Reported by jwhui. Fixes #2242.
