``const u8 *nonce`` The nonce. All (key, nonce) pairs used for encryption MUST be distinct. ``size_t nonce_len`` Length of the nonce in bytes: between 7 and 13 inclusive ``const struct aes_ccm_key *key`` The key, already prepared using aes_ccm_preparekey(). Note that a pointer to the key is saved in the context, so the key must live at least as long as the context. **Description** Unlike AES-GCM, AES-CCM requires the total lengths of the associated data and the en/decrypted data to be known during initialization. Callers MUST ensure that these lengths are correct. If this function returns success, the context should be zeroized at the end of its lifetime. Normally that happens in aes_ccm_encrypt_final() or aes_ccm_decrypt_final(), but callers that abandon a context without finalizing it should explicitly zeroize it. IMPORTANT: Callers that are decrypting MUST NOT assume that any decrypted or associated data is authentic until the authentication tag has been verified. This incremental API is provided solely to support callers that can't efficiently use the one-shot functions due to using a nonlinear data layout. For incremental AES-CCM encryption, use: 1. aes_ccm_init() 2. aes_ccm_auth_update() (any number of times) 3. aes_ccm_encrypt_update() (any number of times) 4. aes_ccm_encrypt_final() For incremental AES-CCM decryption, use: 1. aes_ccm_init() 2. aes_ccm_auth_update() (any number of times) 3. aes_ccm_decrypt_update() (any number of times) 4. aes_ccm_decrypt_final() **Context** Any context.
