#define PSA_ALG_IS_RSA_PSS(alg) \ (PSA_ALG_IS_RSA_PSS_STANDARD_SALT(alg) || \ PSA_ALG_IS_RSA_PSS_ANY_SALT(alg))

Arguments

Argument

Description

alg

An algorithm value or an algorithm policy wildcard.

Return value

1 if \p alg is of the form #PSA_ALG_RSA_PSS(\c hash_alg) or #PSA_ALG_RSA_PSS_ANY_SALT_BASE(\c hash_alg), where \c hash_alg is a hash algorithm or #PSA_ALG_ANY_HASH. 0 otherwise. This macro may return either 0 or 1 if \p alg is not a supported algorithm identifier or policy.
