Struct Issuer 

pub struct Issuer<'a, S> { /* private fields */ }

Available on (crate features rustls or boring or acme) and crate feature rustls only.

An issuer that can sign certificates.

Encapsulates the distinguished name, key identifier method, key usages and signing key of the issuing certificate.

Implementations

impl<'a, S> Issuer<'a, S>

where S: SigningKey,

pub fn new(params: CertificateParams, signing_key: S) -> Issuer<'a, S>

Create a new issuer from the given parameters and signing key.

pub fn from_params( params: &'a CertificateParams, signing_key: S, ) -> Issuer<'a, S>

Create a new issuer from the given parameters and signing key references.

Use Issuer::new instead if you want to obtain an Issuer that owns its parameters.

pub fn from_ca_cert_pem( pem_str: &str, signing_key: S, ) -> Result<Issuer<'a, S>, Error>

Available on crate features pem and x509-parser only.

Parses an existing CA certificate from the ASCII PEM format.

See from_ca_cert_der for more details.

pub fn from_ca_cert_der( ca_cert: &CertificateDer<'_>, signing_key: S, ) -> Result<Issuer<'a, S>, Error>

Available on crate feature x509-parser only.

Parses an existing CA certificate from the DER format.

This function assumes the provided certificate is a CA. It will not check for the presence of the BasicConstraints extension, or perform any other validation.

If you already have a byte slice containing DER, it can trivially be converted into CertificateDer using the Into trait.

pub fn key_usages(&self) -> &[KeyUsagePurpose]

Allowed key usages for this issuer.

pub fn key(&self) -> &S

Yield a reference to the signing key.

Trait Implementations

impl<'a, S> Debug for Issuer<'a, S>

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

Formats the issuer information without revealing the key pair.
