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.

Constants

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
