When the OpenSSL library is used, standard OpenSSL usage +constants instead of magic numbers. When calling OpenSSL APIs (in test utilities), standard OpenSSL convention is followed by testing return values against the value 1 which represents success. clang-tidy is a linting tool used to diagnose and fixing typical programming errors. diff --git a/reference/src/util/CMakeLists.txt b/reference/src/util/CMakeLists.txt index 2112a5ee..3d094d2a 100644 --- a/reference/src/util/CMakeLists.txt +++ b/reference/src/util/CMakeLists.txt @@ -48,6 +48,7 @@ add_library(util STATIC src/digest_util.c src/log.c + src/root_keystore.c src/sa_rights.c ) diff --git a/reference/src/util/include/common.h b/reference/src/util/include/common.h index 18f52822..0edd4211 100644 --- a/reference/src/util/include/common.h +++ b/reference/src/util/include/common.h @@ -60,7 +60,4 @@ #define MAX_PROPQUERY_SIZE 256 #define MAX_CMAC_SIZE 64 -#define DEFAULT_ROOT_KEYSTORE_PASSWORD "password01234567" -#define COMMON_ROOT_NAME "commonroot" - #endif // UTIL_COMMON_H diff --git a/reference/src/util/include/root_keystore.h b/reference/src/util/include/root_keystore.h index 1f4e836b..81a35e51 100644 --- a/reference/src/util/include/root_keystore.h +++ b/reference/src/util/include/root_keystore.h @@ -1,5 +1,5 @@ /* - * Copyright 2025 Comcast Cable Communications Management, LLC + * Copyright 2025-2026 Comcast Cable Communications Management, LLC * * Licensed under the Apache License, Version 2.0 (the "License");
