Struct webpki::KeyUsage

source · 
pub struct KeyUsage { /* private fields */ }
Expand description

The expected key usage of a certificate.

This type represents the expected key usage of an end entity certificate. Although for most kinds of certificates the extended key usage extension is optional (and so certificates not carrying a particular value in the EKU extension are acceptable). If the extension is present, the certificate MUST only be used for one of the purposes indicated.

Implementations§

source§

impl KeyUsage

source

pub const fn server_auth() -> Self

Construct a new KeyUsage as appropriate for server certificate authentication.

As specified in https://www.rfc-editor.org/rfc/rfc5280#section-4.2.1.12, this does not require the certificate to specify the eKU extension.

source

pub const fn client_auth() -> Self

Construct a new KeyUsage as appropriate for client certificate authentication.

As specified in <>, this does not require the certificate to specify the eKU extension.

source

pub const fn required(oid: &'static [u8]) -> Self

Construct a new KeyUsage requiring a certificate to support the specified OID.

source

pub const fn required_if_present(oid: &'static [u8]) -> Self

Construct a new KeyUsage requiring a certificate to support the specified OID, if the certificate has EKUs.
