- Avoid downgrading TLS ciphersuites when client RSA keys are larger than RSA-2048 bit.
- Note that when using bigger certificates on low-power chips without crypto
hardware acceleration, it is recommended to adjust the task watchdog timer (TWDT)
if it is enabled. For precise information on timing requirements, you can check
performance numbers at https://github.com/espressif/mbedtls/wiki/Performance-Numbers.
