Many of the new types introduced by OpenSSL 3.0 have an OSSL_ prefix, e.g., OSSL_CALLBACK, OSSL_PARAM, OSSL_ALGORITHM, OSSL_SERIALIZER. The OPENSSL_CTX type stands out a little by using a different prefix. For consistency reasons, this type is renamed to OSSL_LIB_CTX.

=head1 NAME
|
|
|
|
SMIME_write_ASN1_ex, SMIME_write_ASN1
|
|
- convert structure to S/MIME format
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/asn1.h>
|
|
|
|
int SMIME_write_ASN1_ex(BIO *out, ASN1_VALUE *val, BIO *data, int flags,
|
|
int ctype_nid, int econt_nid,
|
|
STACK_OF(X509_ALGOR) *mdalgs, const ASN1_ITEM *it,
|
|
OSSL_LIB_CTX *libctx, const char *propq);
|
|
|
|
int SMIME_write_ASN1(BIO *out,
|
|
ASN1_VALUE *val, BIO *data, int flags, int ctype_nid, int econt_nid,
|
|
STACK_OF(X509_ALGOR) *mdalgs, const ASN1_ITEM *it);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
SMIME_write_ASN1_ex() adds the appropriate MIME headers to an object
|
|
structure to produce an S/MIME message.
|
|
|
|
I<out> is the BIO to write the data to. I<value> is the appropriate ASN1_VALUE
|
|
structure (either CMS_ContentInfo or PKCS7). If streaming is enabled then the
|
|
content must be supplied via I<data>.
|
|
I<flags> is an optional set of flags. I<ctype_nid> is the NID of the content
|
|
type, I<econt_nid> is the NID of the embedded content type and I<mdalgs> is a
|
|
list of signed data digestAlgorithms. Valid values that can be used by the
|
|
ASN.1 structure I<it> are ASN1_ITEM_rptr(PKCS7) or ASN1_ITEM_rptr(CMS_ContentInfo).
|
|
The library context I<libctx> and the property query I<propq> are used when
|
|
retrieving algorithms from providers.
|
|
|
|
=head1 NOTES
|
|
|
|
The higher level functions L<SMIME_write_CMS(3)> and
|
|
L<SMIME_write_PKCS7(3)> should be used instead of SMIME_write_ASN1().
|
|
|
|
The following flags can be passed in the B<flags> parameter.
|
|
|
|
If B<CMS_DETACHED> is set then cleartext signing will be used, this option only
|
|
makes sense for SignedData where B<CMS_DETACHED> is also set when the sign()
|
|
method is called.
|
|
|
|
If the B<CMS_TEXT> flag is set MIME headers for type B<text/plain> are added to
|
|
the content, this only makes sense if B<CMS_DETACHED> is also set.
|
|
|
|
If the B<CMS_STREAM> flag is set streaming is performed. This flag should only
|
|
be set if B<CMS_STREAM> was also set in the previous call to a CMS_ContentInfo
|
|
or PKCS7 creation function.
|
|
|
|
If cleartext signing is being used and B<CMS_STREAM> not set then the data must
|
|
be read twice: once to compute the signature in sign method and once to output
|
|
the S/MIME message.
|
|
|
|
If streaming is performed the content is output in BER format using indefinite
|
|
length constructed encoding except in the case of signed data with detached
|
|
content where the content is absent and DER format is used.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
SMIME_write_ASN1_ex() and SMIME_write_ASN1() return 1 for success or
|
|
0 for failure.
