Module cipher

TLS message encryption/decryption interfaces.

Structs

AeadKey

A key for an AEAD algorithm.

BorrowedPayload

InboundOpaqueMessage

A TLS frame, named TLSPlaintext in the standard.

InboundPlainMessage

A TLS frame, named TLSPlaintext in the standard.

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.

OutboundOpaqueMessage

A TLS frame, named TLSPlaintext in the standard.

OutboundPlainMessage

A TLS frame, named TLSPlaintext in the standard.

PlainMessage

A decrypted TLS frame

PrefixedPayload

UnsupportedOperationError

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

Enums

OutboundChunks

A collection of borrowed plaintext slices.

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

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.
