You have several options here.
You can just use the encrypted data type with a key directly.
You can use the enveloped data type with a symmetric wrapping key.
You can use the enveloped data type with a password based recipient info.
Which you use depends on the application you have in mind.
In the first case you just call CMS_EncryptData_encrypt() followed by
