CSFLE Cryptographic Primitives

MongoDB encrypts all fields in CSFLE with the AEAD AES-256-CBC encryption algorithm.

  • If you specify deterministic encryption for a field, your application passes a deterministic initialization vector to AEAD.

  • If you specify random encryption for a field, your application passes a random initialization vector to AEAD.

Note

Authenticated Encryption

MongoDB CSFLE uses the encrypt-then-MAC approach to perform authenticated encryption. MongoDB CSFLE uses the HMAC-SHA-512 algorithm to generate your MAC.
