+/**
+ * \file psa/crypto_legacy.h
+ *
+ * \brief Add temporary suppport for deprecated symbols before they are
+ *        removed from the library.
+ *
+ * PSA_WANT_KEY_TYPE_xxx_KEY_PAIR_LEGACY and
+ * MBEDTLS_PSA_ACCEL_KEY_TYPE_ECC_KEY_PAIR_LEGACY symbols are deprecated.
+ * New symols add a suffix to that base name in order to clearly state what is
+ * the expected use for the key (use, import, export, generate, derive).
+ * Here we define some backward compatibility support for uses stil using
+ * the legacy symbols.
