Allocation strategy for mbedTLS, essentially provides ability to
|
|
allocate all required dynamic allocations from,
|
|
|
|
- Internal DRAM memory only
|
|
- External SPIRAM memory only
|
|
- Either internal or external memory based on default malloc()
|
|
behavior in ESP-IDF
|
|
- Custom allocation mode, by overwriting calloc()/free() using
|
|
mbedtls_platform_set_calloc_free() function
|
|
|
|
Recommended mode here is always internal, since that is most preferred
|
|
from security perspective. But if application requirement does not
|
|
allow sufficient free internal memory then alternate mode can be
|
|
selected.

Maximum TLS message length (in bytes) supported by mbedTLS.
|
|
|
|
16384 is the default and this value is required to comply
|
|
fully with TLS standards.
|
|
|
|
However you can set a lower value in order to save RAM. This
|
|
is safe if the other end of the connection supports Maximum
|
|
Fragment Length Negotiation Extension (max_fragment_length,
|
|
see RFC6066) or you know for certain that it will never send a
|
|
message longer than a certain number of bytes.
|
|
|
|
If the value is set too low, symptoms are a failed TLS

handshake or a return value of MBEDTLS_ERR_SSL_INVALID_RECORD

Due to a hardware limitation, hardware acceleration is only

guaranteed if SHA digests are calculated one at a time. If more

than one SHA digest is calculated at the same time, one will

be calculated fully in hardware and the rest will be calculated

slower in others. You should benchmark to find the best setting for you.
