Module cipher 

TLS message encryption/decryption interfaces.

Structs

AeadKey

A key for an AEAD algorithm.

EncryptBuffer

A fixed-size buffer into which a RecordEncrypter writes an encrypted record 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 records on a connection.

Record

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

UnsupportedOperationError

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

Enums

EncodableVersion

A protocol version that can be encoded.

OutboundPlain

A collection of borrowed plaintext slices.

Payload

An externally length’d payload

RecordError

Errors from trying to parse a TLS record.

Constants

NONCE_LEN

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

Traits

RecordDecrypter

Objects with this trait can decrypt TLS records.

RecordEncrypter

Objects with this trait can encrypt TLS records.

Tls12AeadAlgorithm

Factory trait for building RecordEncrypter and RecordDecrypter for a TLS1.2 cipher suite.

Tls13AeadAlgorithm

Factory trait for building RecordEncrypter and RecordDecrypter 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.
