Differences Between Probabilistic and Deterministic Encryption

In Shield Platform Encryption, probabilistic encryption randomizes the ciphertext output each time the same plaintext is encrypted. This enhancing security by making patterns harder to discern but it also prevents filtering or exact-match searches on encrypted data. Conversely, deterministic encryption always produces the same ciphertext for a given plaintext. This allows for filtering, sorting, and equality comparisons on encrypted fields, but with a slight reduction in randomness compared to probabilistic encryption.
