SYNOPSIS

9       #include <gnutls/pkcs7.h>
10
11       int  gnutls_pkcs7_sign(gnutls_pkcs7_t  pkcs7, gnutls_x509_crt_t signer,
12       gnutls_privkey_t   signer_key,    const    gnutls_datum_t    *    data,
13       gnutls_pkcs7_attrs_t signed_attrs, gnutls_pkcs7_attrs_t unsigned_attrs,
14       gnutls_digest_algorithm_t dig, unsigned flags);
15

ARGUMENTS

17       gnutls_pkcs7_t pkcs7
18                   should contain a gnutls_pkcs7_t type
19
20       gnutls_x509_crt_t signer
21                   the certificate to sign the structure
22
23       gnutls_privkey_t signer_key
24                   the key to sign the structure
25
26       const gnutls_datum_t * data
27                   The data to be signed or  NULL  if  the  data  are  already
28                   embedded
29
30       gnutls_pkcs7_attrs_t signed_attrs
31                   Any additional attributes to be included in the signed ones
32                   (or NULL)
33
34       gnutls_pkcs7_attrs_t unsigned_attrs
35                   Any additional attributes to be included  in  the  unsigned
36                   ones (or NULL)
37
38       gnutls_digest_algorithm_t dig
39                   The digest algorithm to use for signing
40
41       unsigned flags
42                   Should be zero or one of GNUTLS_PKCS7 flags
43

DESCRIPTION

45       This function will add a signature in the provided PKCS 7 structure for
46       the provided data. Multiple signatures can be made with different sign‐
47       ers.
48
49       The       available       flags      are:      GNUTLS_PKCS7_EMBED_DATA,
50       GNUTLS_PKCS7_INCLUDE_TIME,        GNUTLS_PKCS7_INCLUDE_CERT,        and
51       GNUTLS_PKCS7_WRITE_SPKI.      They     are     explained     in     the
52       gnutls_pkcs7_sign_flags definition.
53

RETURNS

55       On success, GNUTLS_E_SUCCESS (0)  is  returned,  otherwise  a  negative
56       error value.
