Functions
esp_err_t esp_crt_bundle_attach(void *conf)
Attach and enable use of a bundle for certificate verification.
Attach and enable use of a bundle for certificate verification through a verification callback. If no specific bundle
has been set through esp_crt_bundle_set() it will default to the bundle defined in menuconfig and embedded in
the binary.
Return
• ESP_OK if adding certificates was successful.
• Other if an error occured or an action must be taken by the calling process.
Parameters
• [in] conf: The config struct for the SSL connection.
void esp_crt_bundle_detach(mbedtls_ssl_config *conf)
Disable and dealloc the certification bundle.
Removes the certificate verification callback and deallocates used resources
Parameters
• [in] conf: The config struct for the SSL connection.
void esp_crt_bundle_set(const uint8_t *x509_bundle)
Set the default certificate bundle used for verification.
Overrides the default certificate bundle. In most use cases the bundle should be set through menuconfig. The
bundle needs to be sorted by subject name since binary search is used to find certificates.
Parameters
• [in] x509_bundle: A pointer to the certificate bundle.

provisioning (or non-provisioning) use cases.
Following features are available for provisioning :
• Communication security at application level -
– protocomm_security0 (no security)
– protocomm_security1 (curve25519 key exchange + AES-CTR encryption)
• Proof-of-possession (support with protocomm_security1 only)
