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(3) 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(3)
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.
