26 CMS_EncryptedData_encrypt_ex() creates a B<CMS_ContentInfo> structure
27 with a type B<NID_pkcs7_encrypted>. I<in> is a BIO containing the data to
28 encrypt using I<cipher> and the encryption key I<key> of size I<keylen> bytes.
29 The library context I<libctx> and the property query I<propq> are used when
30 retrieving algorithms from providers. I<flags> is a set of optional flags.
32 The I<flags> field supports the options B<CMS_DETACHED>, B<CMS_STREAM> and
33 B<CMS_PARTIAL>. Internally CMS_final() is called unless B<CMS_STREAM> and/or
34 B<CMS_PARTIAL> is specified.
36 The algorithm passed in the I<cipher> parameter must support ASN1 encoding of
39 The B<CMS_ContentInfo> structure can be freed using L<CMS_ContentInfo_free(3)>.
41 CMS_EncryptedData_encrypt() is similar to CMS_EncryptedData_encrypt_ex()
42 but uses default values of NULL for the library context I<libctx> and the
43 property query I<propq>.
47 If the allocation fails, CMS_EncryptedData_encrypt_ex() and
48 CMS_EncryptedData_encrypt() return NULL and set an error code that can be
49 obtained by L<ERR_get_error(3)>. Otherwise they return a pointer to the newly
54 L<ERR_get_error(3)>, L<CMS_final(3)>, L<CMS_EncryptedData_decrypt(3)>
58 The CMS_EncryptedData_encrypt_ex() method was added in OpenSSL 3.0.
