13 const EVP_CIPHER *cipher, const unsigned char *key, size_t keylen,
14 unsigned int flags, OPENSSL_CTX *ctx, const char *propq);
16 CMS_ContentInfo *CMS_EncryptedData_encrypt(BIO *in,
17 const EVP_CIPHER *cipher, const unsigned char *key, size_t keylen,
22 CMS_EncryptedData_encrypt_with_libctx() creates a B<CMS_ContentInfo> structure
23 with a type B<NID_pkcs7_encrypted>. I<in> is a BIO containing the data to
24 encrypt using I<cipher> and the encryption key I<key> of size I<keylen> bytes.
25 The library context I<libctx> and the property query I<propq> are used when
26 retrieving algorithms from providers. I<flags> is a set of optional flags.
28 The I<flags> field supports the options B<CMS_DETACHED>, B<CMS_STREAM> and
29 B<CMS_PARTIAL>. Internally CMS_final() is called unless B<CMS_STREAM> and/or
30 B<CMS_PARTIAL> is specified.
32 The algorithm passed in the I<cipher> parameter must support ASN1 encoding of
35 The B<CMS_ContentInfo> structure can be freed using L<CMS_ContentInfo_free(3)>.
37 CMS_EncryptedData_encrypt() is similar to CMS_EncryptedData_encrypt_with_libctx()
38 but uses default values of NULL for the library context I<libctx> and the
39 property query I<propq>.
43 If the allocation fails, CMS_EncryptedData_encrypt_with_libctx() and
44 CMS_EncryptedData_encrypt() return NULL and set an error code that can be
45 obtained by L<ERR_get_error(3)>. Otherwise they return a pointer to the newly
50 L<ERR_get_error(3)>, L<CMS_final(3)>, L<CMS_EncryptedData_decrypt(3)>
54 The CMS_EncryptedData_encrypt_with_libctx() method was added in OpenSSL 3.0.
