MBEDTLS_ECP_DP_SECP521R1_ENABLED as well as modified config.
But situation is the same.
I don’t know but openssl works fine on local machine using the same pairs.
My server do not uses time. As well it does not use date_time.
But client uses.
Server hello message send some data in the time field, and this data corresponds the time from future.
Can it be an issue?
What should I do with function
There is only CA cert sends to this function in mbedtls examples.
But from tls1.2 handshake description I see that full chain should be sent.
Which way is correct?
