Module cipher 

TLS message encryption/decryption interfaces.

Structs

AeadKey

A key for an AEAD algorithm.

EncodedMessage

A TLS message with encoded (but not necessarily encrypted) payload.

InboundOpaque

A borrowed payload buffer.

Iv

A write or read IV.

KeyBlockShape

How a TLS1.2 key_block is partitioned.

Nonce

A nonce. This is unique for all messages on a connection.

OutboundOpaque

A payload buffer with space reserved at the front for a TLS message header.

UnsupportedOperationError

An error indicating that the AEAD algorithm does not support the requested operation.

Enums

MessageError

Errors from trying to parse a TLS message.

OutboundPlain

A collection of borrowed plaintext slices.

Payload

An externally length’d payload

Constants

NONCE_LEN

Size of TLS nonces (incorrectly termed “IV” in standard) for all supported ciphersuites (AES-GCM, Chacha20Poly1305)

Traits

MessageDecrypter

Objects with this trait can decrypt TLS messages.

MessageEncrypter

Objects with this trait can encrypt TLS messages.

Tls12AeadAlgorithm

Factory trait for building MessageEncrypter and MessageDecrypter for a TLS1.2 cipher suite.

Tls13AeadAlgorithm

Factory trait for building MessageEncrypter and MessageDecrypter for a TLS1.3 cipher suite.

Functions

make_tls12_aad

Returns a TLS1.2 additional_data encoding.

make_tls13_aad

Returns a TLS1.3 additional_data encoding.
