"DESCRIPTION"
Header "DESCRIPTION" \fBCMS_EncryptedData_encrypt_ex() creates a CMS_ContentInfo structure
with a type NID_pkcs7_encrypted. in is a \s-1BIO\s0 containing the data to
encrypt using cipher and the encryption key key of size keylen bytes.
The library context libctx and the property query propq are used when
retrieving algorithms from providers. flags is a set of optional flags.
The flags field supports the options \s-1CMS_DETACHED\s0, \s-1CMS_STREAM\s0 and \fB\s-1CMS_PARTIAL\s0. Internally CMS_final() is called unless \s-1CMS_STREAM\s0 and/or \fB\s-1CMS_PARTIAL\s0 is specified.
The algorithm passed in the cipher parameter must support \s-1ASN1\s0 encoding of its parameters.
The CMS_ContentInfo structure can be freed using CMS_ContentInfo_free\|(3).
\fBCMS_EncryptedData_encrypt() is similar to CMS_EncryptedData_encrypt_ex() but uses default values of \s-1NULL\s0 for the library context libctx and the property query propq.
"RETURN VALUES"
Header "RETURN VALUES" If the allocation fails, CMS_EncryptedData_encrypt_ex() and
\fBCMS_EncryptedData_encrypt() return \s-1NULL\s0 and set an error code that can be
obtained by ERR_get_error\|(3). Otherwise they return a pointer to the newly
allocated structure.

Header "HISTORY" The CMS_EncryptedData_encrypt_ex() method was added in OpenSSL 3.0.
