25 CMS_EncryptedData_encrypt_ex() creates a CMS_ContentInfo structure with
26 a type NID_pkcs7_encrypted. in is a BIO containing the data to encrypt
27 using cipher and the encryption key key of size keylen bytes. The
28 library context libctx and the property query propq are used when
29 retrieving algorithms from providers. flags is a set of optional flags.
30
31 The flags field supports the options CMS_DETACHED, CMS_STREAM and
32 CMS_PARTIAL. Internally CMS_final() is called unless CMS_STREAM and/or
33 CMS_PARTIAL is specified.
34
35 The algorithm passed in the cipher parameter must support ASN1 encoding
36 of its parameters.
37
38 The CMS_ContentInfo structure can be freed using
39 CMS_ContentInfo_free(3).
40
41 CMS_EncryptedData_encrypt() is similar to
42 CMS_EncryptedData_encrypt_ex() but uses default values of NULL for the
43 library context libctx and the property query propq.
44
46 If the allocation fails, CMS_EncryptedData_encrypt_ex() and
47 CMS_EncryptedData_encrypt() return NULL and set an error code that can
48 be obtained by ERR_get_error(3). Otherwise they return a pointer to the
49 newly allocated structure.

55 The CMS_EncryptedData_encrypt_ex() method was added in OpenSSL 3.0.
