SYNOPSIS

10        #include <openssl/evp.h>
11        int EVP_PKEY_digestsign_supports_digest(EVP_PKEY *pkey, OSSL_LIB_CTX *libctx,
12                                                const char *name, const char *propq);

DESCRIPTION

15       The EVP_PKEY_digestsign_supports_digest() function queries whether the
16       message digest name is supported for public key signature operations
17       associated with key pkey. The query is done within an optional library
18       context libctx and with an optional property query propq.
19

RETURN VALUES

21       The EVP_PKEY_digestsign_supports_digest() function returns 1 if the
22       message digest algorithm identified by name can be used for public key
23       signature operations associated with key pkey and 0 if it cannot be
24       used. It returns a negative value for failure.
