There are two types of Shield Encryption: Deterministic & Probabilistic. Deterministic encryption is for the field which you need in the where clause in a query but the Probabilistic type ensures extra security than the Deterministic type.
Don’t get confused between Classic encryption and Shield platform encryption, Classic encryption is also provided on top of platform with no cost but it doesn’t support Standard field, File, also it provides 128 bit AES and user access to encryption filed is managed by permission set
