Configuration

Kconfig library configuration

LIBEDHOC_ENABLE

Enable building libedhoc for Zephyr target.

LIBEDHOC_KEY_ID_LEN

Key identifier length in bytes.

LIBEDHOC_MAX_NR_OF_CIPHER_SUITES

Maximum number of cipher suites in chain for negotiation.

Values greater than 3 require regeneration of the CBOR backend.

LIBEDHOC_MAX_LEN_OF_CONN_ID

Maximum length of connection identifier in bytes.

LIBEDHOC_MAX_LEN_OF_ECC_KEY

Maximum length of ECC (Elliptic Curve Cryptography) key in bytes.

LIBEDHOC_MAX_LEN_OF_MAC

Maximum length of hash in bytes.

LIBEDHOC_MAX_NR_OF_EAD_TOKENS

Maximum number of EAD (External Authorization Data) tokens.

Values greater than 3 require regeneration of the CBOR backend.

LIBEDHOC_MAX_NR_OF_CERTS_IN_X509_CHAIN

Maximum number of certificates in X.509 chain.

Values greater than 3 require regeneration of the CBOR backend.

LIBEDHOC_MAX_LEN_OF_CRED_KEY_ID

Maximum length of authentication credentials key identifier in bytes.

LIBEDHOC_MAX_LEN_OF_HASH_ALG

Maximum length of authentication credentials hash algorithm in bytes.

Linux target

All configuration parameters listed above must be passed as compiler defines during the build.

Each must be prefixed with CONFIG_.

Zephyr target

The library can be used as a Zephyr module. A west manifest is provided for easy integration.

Initialize workspace:

west init -l libedhoc
west update

Build sample application:

west build -b native_sim libedhoc/sample/benchmark

All Kconfig options are automatically prefixed with CONFIG_ by the Zephyr build system.

Dependencies (zcbor, mbedtls) are automatically pulled via the west manifest.
