Family Group

AES Family

The Advanced Encryption Standard (AES) family of symmetric block ciphers and modes of operation. Standardized by NIST and widely used globally.

Key Features & Capabilities

  • Confidentiality using block ciphers
  • Authenticated encryption options (GCM, CCM)
  • Disk encryption capability (XTS)
  • Standardized key sizes (128, 192, 256 bits)

Algorithms in this Collection

AES

symmetric

Recommended

Advanced Encryption Standard. A highly secure, standard block cipher supporting key sizes of 128, 192, or 256 bits.

AES-CCM

symmetric

Secure

Counter with CBC-MAC (NIST SP 800-38C) — an authenticated mode composed from AES, contrasted with AES-GCM: authentication here is literal CBC-MAC re-running the block cipher, not GHASH polynomial evaluation.

AES-XTS

symmetric

Secure

A tweakable mode (IEEE P1619) for disk-sector encryption, composed from the existing AES module — the sector number IS the tweak, so no IV needs to be stored per sector. Confidentiality-only, no authentication tag (unlike AES-GCM).
