Always Encrypted: Deterministic vs. Randomized

WebThe randomized encryption algorithm always returns a different unique value while the deterministic algorithm always returns the same value. Queries expecting deterministically encrypted data for that field return inconsistent results, as the server cannot match any of the randomly encrypted fields. WebSep 7, 2024 · Deterministic encryption must use a column collation with a binary2 sort order for character columns. Randomized encryption uses a method that encrypts data in a less predictable manner. Randomized encryption is more secure, but prevents searching, grouping, indexing, and joining on encrypted columns." shun traduction
