Always Encrypted option where encrypting the same value gives new ciphertext every time. It is stronger than deterministic encryption, but the column can no longer be searched, grouped, joined or indexed.

Terms in this definition
- Always Encrypted
Client-side encryption of SQL columns using keys never revealed to the database engine, meaning cloud administrators and DBAs only ever see ciphertext.
- WHERE
Limits a SELECT, UPDATE or DELETE to just the rows meeting a condition. Omit it, and the statement hits every row.
- Deterministic encryption
Always Encrypted option where a given value always encrypts to identical ciphertext. That allows equality searches, joins, grouping and indexes, at the cost of exposing patterns in the data.
