CMS_DIGEST_CREATE(3ossl)	    OpenSSL	      CMS_DIGEST_CREATE(3ossl)

NAME
       CMS_digest_create_ex, CMS_digest_create - Create	CMS DigestedData
       object

SYNOPSIS
	#include <openssl/cms.h>

	CMS_ContentInfo	*CMS_digest_create_ex(BIO *in, const EVP_MD *md,
					      unsigned int flags, OSSL_LIB_CTX *ctx,
					      const char *propq);

	CMS_ContentInfo	*CMS_digest_create(BIO *in, const EVP_MD *md,
					   unsigned int	flags);

DESCRIPTION
       CMS_digest_create_ex() creates a	CMS_ContentInfo	structure with a type
       NID_pkcs7_digest. The data supplied via the in BIO is digested using
       md. The library context libctx and the property query propq are used
       when retrieving algorithms from providers.  The flags field supports
       the CMS_DETACHED	and CMS_STREAM flags, Internally CMS_final() is	called
       unless CMS_STREAM is specified.

       The CMS_ContentInfo structure can be freed using
       CMS_ContentInfo_free(3).

       CMS_digest_create() is similar to CMS_digest_create_ex()	but uses
       default values of NULL for the library context libctx and the property
       query propq.

RETURN VALUES
       If the allocation fails,	CMS_digest_create_ex() and CMS_digest_create()
       return NULL and set an error code that can be obtained by
       ERR_get_error(3).  Otherwise they return	a pointer to the newly
       allocated structure.

SEE ALSO
       ERR_get_error(3), CMS_final(3)>

       The CMS_digest_create_ex() method was added in OpenSSL 3.0.
