PSA_ALG_IS_WILDCARD macro
Whether the specified algorithm encoding is a wildcard. Wildcard values may only be used to set the usage algorithm field in a policy, not to perform an operation.
Syntax
#define PSA_ALG_IS_WILDCARD(alg) \
(PSA_ALG_IS_HASH_AND_SIGN(alg) ? \
PSA_ALG_SIGN_GET_HASH(alg) == PSA_ALG_ANY_HASH : \
PSA_ALG_IS_MAC(alg) ? \
(alg & PSA_ALG_MAC_AT_LEAST_THIS_LENGTH_FLAG) != 0 : \
PSA_ALG_IS_AEAD(alg) ? \
(alg & PSA_ALG_AEAD_AT_LEAST_THIS_LENGTH_FLAG) != 0 : \
(alg) == PSA_ALG_ANY_HASH)
Return value
1 if \c alg is a wildcard algorithm encoding. 0 if \c alg is a non-wildcard algorithm encoding (suitable for an operation). This macro may return either 0 or 1 if \c alg is not a supported algorithm identifier.
