15 CMS_ContentInfo *CMS_EnvelopedData_create(const EVP_CIPHER *cipher);
19 CMS_EnvelopedData_create_with_libctx() creates a B<CMS_ContentInfo> structure with
20 a type B<NID_pkcs7_enveloped>. I<cipher> is the symmetric cipher to use. The
21 library context I<libctx> and the property query I<propq> are used when
22 retrieving algorithms from providers.
24 The algorithm passed in the I<cipher> parameter must support ASN1 encoding of
27 The recipients can be added later using L<CMS_add1_recipient_cert(3)> or
28 L<CMS_add0_recipient_key(3)>.
30 The B<CMS_ContentInfo> structure needs to be finalized using L<CMS_final(3)>
31 and then freed using L<CMS_ContentInfo_free(3)>.
33 CMS_EnvelopedData_create() is similar to CMS_EnvelopedData_create_with_libctx()
34 but uses default values of NULL for the library context I<libctx> and the
35 property query I<propq>.
39 Although CMS_EnvelopedData_create() allocates a new B<CMS_ContentInfo>
40 structure it is usually not used in applications. The wrappers
41 L<CMS_encrypt(3)> and L<CMS_decrypt(3)> are often used instead.
45 If the allocation fails, CMS_EnvelopedData_create() returns NULL and sets
46 an error code that can be obtained by L<ERR_get_error(3)>.
47 Otherwise it returns a pointer to the newly allocated structure.
