PKCS7_SET_CONTENT(3) | Library Functions Manual | PKCS7_SET_CONTENT(3) |
PKCS7_set_content
,
PKCS7_content_new
— set the
nested contentInfo in a PKCS#7 structure
#include
<openssl/pkcs7.h>
int
PKCS7_set_content
(PKCS7 *outer,
PKCS7 *inner);
int
PKCS7_content_new
(PKCS7 *outer,
int inner_type);
If the contentType of the
outer PKCS7 structure is
SignedData or DigestedData,
PKCS7_set_content
()
sets the contentInfo field of the
content field of outer to
inner, without copying inner. If
there was previous contentInfo, it is freed rather
than overwritten. The rest of the internal state of
outer and of its content remains
unchanged.
PKCS7_content_new
()
is similar except that it first allocates and initializes a new, empty
inner object of the given
inner_type using
PKCS7_new(3) and
PKCS7_set_type(3). The
inner_type can be any of the NIDs listed in the
PKCS7_set_type(3) manual.
These functions return 1 on success or 0 on failure. They fail if
the contentType of outer is
unsupported. PKCS7_content_new
() can also fail when
memory is exhausted. In case of failure, outer remains
unchanged.
PKCS7_dataInit(3), PKCS7_new(3), PKCS7_set_type(3), PKCS7_sign(3)
RFC 2315: PKCS #7: Cryptographic Message Syntax Version 1.5
These functions first appeared in SSLeay 0.8.1 and have been available since OpenBSD 2.4.
Despite the function names, these functions do not set the content field of outer, but only the contentInfo field inside it. The rest of the content remains unchanged.
