+# Suppress deprecated warnings for OpenSSL deprecated APIs
+# 
+# Why suppress instead of fixing:
+# 1. EC Key Management: libspdm_ec_set_pub_key/libspdm_ec_set_priv_key use deprecated EC_KEY APIs
+#    as fallback when modern EVP_PKEY_set* methods fail. This ensures compatibility when keys
+#    are set separately (public first, then private).
+#
+# 2. SM2 Implementation: os_stub/cryptlib_openssl/pk/sm2.c uses deprecated EC_KEY APIs throughout.
+#    Full migration to modern APIs requires significant refactoring.
+#
+# 3. FIPS Mode: libspdm_ecdsa_sign_ex uses deprecated APIs for custom random number injection,
+#    which is required for FIPS testing (only compiled when LIBSPDM_FIPS_MODE is enabled).
+#
+# Cross-platform suppression:
+# - GCC/Clang (Linux/macOS): -Wno-deprecated-declarations
+# - MSVC (Windows): /wd4996
