Crate hctr2

HCTR2 implements the HCTR2 length-preserving encryption algorithm.

HCTR2 is designed for situations where the length of the ciphertext must exactly match the length of the plaintext, like disk encryption.

This implementation uses a hardware-accelerated POLYVAL implementation when possible; the block cipher is left to the caller. The recommended block cipher is AES.

Structs

• Cipher
  Cipher is an instance of the HCTR2 cipher.

Constants

• BLOCK_SIZE
  BLOCK_SIZE is the size of the block allowed by this package.
