// The below is currenlty not used, CA validation takes too much memory and compute time.
// Please use fingerprint validation instead
// However, the CA are available below for future use if it appears to be useful
//
// Certificates are stored in flash (PROGMEM) to avoid consuming valuable RAM.
//
// To save space in flash, the Let's Encrypt and Amazon AWS certificates may be
// individually omitted if TLS is enabled, but the certificates are not used.
// This is typically the case when a locally generated root certificate is used
// for TLS authentication.
//
// To omit these certificates, define one or both of the
// OMIT_LETS_ENCRYPT_CERT and/or OMIT_AWS_CERT macros in user_config_override.h.
//
// To include a locally generated root certificate, define the
// INCLUDE_LOCAL_CERT macro in user_config_override.h.
//
// See the files tasmota/local_ca_data_sample.h and tasmota/local_ca_descriptor_sample.h
// in the Tasmota source for instructions for generating them from a local root
// certificate in .crt format.
//
// Note: Using full certificate verification increases the amount of time
// required to create a TLS connection, compared to fingerprint validation.
