Enum ContentFormat

pub(crate) enum ContentFormat {
    Utf8,
    Pkcs8PrivateKey,
    SPKIPublicKeyDer,
    CoseKey,
    CoseSign1,
    BitwardenLegacyKey,
    OctetStream,
}

The content format describes the format of the contained bytes. Message encryption always happens on the byte level, and this allows determining what format the contained data has. For instance, an EncString in most cases contains UTF-8 encoded text. In some cases it may contain a Pkcs8 private key, or a COSE key. Specifically, for COSE keys, this allows distinguishing between the old symmetric key format, represented as ContentFormat::OctetStream, and the new COSE key format, represented as ContentFormat::CoseKey.

Variants

Utf8

UTF-8 encoded text

Pkcs8PrivateKey

Pkcs8 private key DER

SPKIPublicKeyDer

SPKI public key DER

CoseKey

COSE serialized CoseKey

CoseSign1

CoseSign1 message

BitwardenLegacyKey

Bitwarden Legacy Key There are three permissible byte values here:

• [u8; 32] - AES-CBC (no hmac) key. This is to be removed and banned.
• [u8; 64] - AES-CBC with HMAC key. This is the v1 userkey key type
• [u8; >64] - COSE key. Padded to be larger than 64 bytes.

OctetStream

Stream of bytes

Trait Implementations

impl Clone for ContentFormat

fn clone(&self) -> ContentFormat

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ContentFormat

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<ContentFormat> for HeaderBuilder

fn from(format: ContentFormat) -> Self

Converts to this type from the input type.

impl PartialEq for ContentFormat

fn eq(&self, other: &ContentFormat) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&Header> for ContentFormat

type Error = CryptoError

The type returned in the event of a conversion error.

fn try_from(header: &Header) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for ContentFormat

impl StructuralPartialEq for ContentFormat
