@brief Initialize new cipher state

@param cipher cipher struct to init (already allocated memory) @param cipher_id cipher algorithm id @param key encryption key to use @param key_size length of the encryption key

@return CIPHER_INIT_SUCCESS if the initialization was successful. @return CIPHER_ERR_BAD_CONTEXT_SIZE if CIPHER_MAX_CONTEXT_SIZE has not been defined (which means that the cipher has not been included in the build) @return The command may return CIPHER_ERR_INVALID_KEY_SIZE if the key size is not valid.
