Module tink_aead::subtle

Provides subtle implementations of the tink_core::Aead primitive.

Structs

• AesCtr
  AesCtr is an implementation of AEAD interface.
• AesGcm
  AesGcm is an implementation of the tink_core::Aead trait.
• AesGcmSiv
  AesGcmSiv is an implementation of the tink_core::Aead trait.
• ChaCha20Poly1305
  ChaCha20Poly1305 is an implementation of the tink_core::Aead trait.
• EncryptThenAuthenticate
  EncryptThenAuthenticate performs an encrypt-then-MAC operation on plaintext and additional authenticated data (aad). The MAC is computed over (aad || ciphertext || size of aad). This implementation is based on http://tools.ietf.org/html/draft-mcgrew-aead-aes-cbc-hmac-sha2-05.
• XChaCha20Poly1305
  XChaCha20Poly1305 is an implementation of the tink_core::Aead trait.

• AES_BLOCK_SIZE_IN_BYTES
• AES_CTR_MIN_IV_SIZE
  The minimum IV size that this implementation supports.
• AES_GCM_IV_SIZE
  The only IV size that this implementation supports.
• AES_GCM_SIV_NONCE_SIZE
  The only IV size that this implementation supports.
• AES_GCM_SIV_TAG_SIZE
  The only tag size that this implementation supports.
• AES_GCM_TAG_SIZE
  The only tag size that this implementation supports.
• CHA_CHA20_KEY_SIZE
  Size of a ChaCh20 key in bytes.
• CHA_CHA20_NONCE_SIZE
  Size of a ChaCh20 nonce in bytes.
• X_CHA_CHA20_KEY_SIZE
  Size of an XChaCh20 key in bytes.
• X_CHA_CHA20_NONCE_SIZE
  Size of an XChaCh20 nonce in bytes.

Traits

• IndCpaCipher
• IndCpaCipherBoxClone
  Trait bound to indicate that primitive trait objects should support cloning themselves as trait objects.

Functions

• validate_aes_key_size
  Check if the given key size is a valid AES key size.
