Struct KeyUsage 

pub struct KeyUsage<'a> { /* private fields */ }

The purposes a key may be used for, as the bits the certificate set.

Implementations

impl<'a> KeyUsage<'a>

pub fn digital_signature(self) -> bool

Signing data.

pub fn content_commitment(self) -> bool

Signing in a way the signer is not meant to be able to deny later, which is the bit a signature under the Regulation rests on.

pub fn key_encipherment(self) -> bool

Enciphering a key.

pub fn data_encipherment(self) -> bool

Enciphering data directly.

pub fn key_agreement(self) -> bool

Agreeing a key.

pub fn key_cert_sign(self) -> bool

Signing certificates, which is what makes a certification authority one.

pub fn crl_sign(self) -> bool

Signing revocation lists.

pub fn encipher_only(self) -> bool

Enciphering only, which means something only alongside key agreement.

pub fn decipher_only(self) -> bool

Deciphering only, on the same terms.

pub fn bits(self) -> BitString<'a>

The bits as they were written, for a report that has to say what a certificate carries rather than what it means.

pub fn read<W: Work>(extension: &Extension<'a>, execution: &W) -> Result<Self>

Reads the value of a key usage extension.

Trait Implementations

impl<'a> Clone for KeyUsage<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for KeyUsage<'a>

impl<'a> Debug for KeyUsage<'a>

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

Formats the value using the given formatter.
