CONFIG_MBEDTLS_CUSTOM_CERTIFICATE_BUNDLE
Add custom certificates to the default bundle
Found in: Component config > mbedTLS > Certificate Bundle > CON-
FIG_MBEDTLS_CERTIFICATE_BUNDLE
Default value:
• No (disabled)
CONFIG_MBEDTLS_CUSTOM_CERTIFICATE_BUNDLE_PATH
Custom certificate bundle path
Found in: Component config > mbedTLS > Certificate Bundle > CON-
FIG_MBEDTLS_CERTIFICATE_BUNDLE > CONFIG_MBEDTLS_CUSTOM_CERTIFICATE_BUNDLE
Name of the custom certificate directory or file. This path is evaluated relative to the project root direc-
tory.
CONFIG_MBEDTLS_ECP_RESTARTABLE
Enable mbedTLS ecp restartable
Found in: Component config > mbedTLS
Enable “non-blocking”ECC operations that can return early and be resumed.
Default value:
• No (disabled)
CONFIG_MBEDTLS_CMAC_C
Enable CMAC mode for block ciphers
Found in: Component config > mbedTLS
Enable the CMAC (Cipher-based Message Authentication Code) mode for block ciphers.
Default value:
• No (disabled)
CONFIG_MBEDTLS_HARDWARE_AES
Enable hardware AES acceleration
Found in: Component config > mbedTLS
Enable hardware accelerated AES encryption & decryption.
Note that if the ESP32 CPU is running at 240MHz, hardware AES does not offer any speed boost over
software AES.
Default value:
• Yes (enabled) if SPIRAM_CACHE_WORKAROUND_STRATEGY_DUPLDST
CONFIG_MBEDTLS_AES_USE_INTERRUPT
Use interrupt for long AES operations
Found in: Component config > mbedTLS > CONFIG_MBEDTLS_HARDWARE_AES
Use an interrupt to coordinate long AES operations.
This allows other code to run on the CPU while an AES operation is pending. Otherwise the CPU
busy-waits.
