Changes
- * Changed the default MBEDTLS_ECP_WINDOW_SIZE from 2 to 3.
- The correlation between this define and RSA decryption performance has
- changed lately due to security hardening.
- To fix the performance degradation when using default values the
- window was increased from 2 to 3.
+ * mbedtls_mpi_exp_mod and code that uses it, notably RSA and DHM operations,
+ have changed their speed/memory compromise as part of a proactive security
+ improvement. The new default value of MBEDTLS_MPI_WINDOW_SIZE roughly
+ preserves the current speed, at the expense of increasing memory
+ consumption.
