Struct CertificateRevocationList 

pub struct CertificateRevocationList<'a> {
    pub tbs_cert_list: TbsCertList<'a>,
    pub signature_algorithm: AlgorithmIdentifier<'a>,
    pub signature_value: BitString<'a>,
    /* private fields */
}

Available on crate feature crypto only.

An X.509 v2 Certificate Revocation List (CRL).

X.509 v2 CRLs are defined in RFC5280.

Example

To parse a CRL and print information about revoked certificates:

use x509_parser::prelude::FromDer;
use x509_parser::revocation_list::CertificateRevocationList;

let res = CertificateRevocationList::from_der(DER);
match res {
    Ok((_rem, crl)) => {
        for revoked in crl.iter_revoked_certificates() {
            println!("Revoked certificate serial: {}", revoked.raw_serial_as_string());
            println!("  Reason: {}", revoked.reason_code().unwrap_or_default().1);
        }
    },
    _ => panic!("CRL parsing failed: {:?}", res),
}

Fields

tbs_cert_list: TbsCertList<'a>

signature_algorithm: AlgorithmIdentifier<'a>

signature_value: BitString<'a>

Implementations

impl<'a> CertificateRevocationList<'a>

pub fn version(&self) -> Option<X509Version>

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

Get the version of the encoded certificate

pub fn issuer(&self) -> &X509Name<'_>

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

Get the certificate issuer.

pub fn last_update(&self) -> ASN1Time

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

Get the date and time of the last (this) update.

pub fn next_update(&self) -> Option<ASN1Time>

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

Get the date and time of the next update, if present.

pub fn iter_revoked_certificates( &self, ) -> impl Iterator<Item = &RevokedCertificate<'a>>

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

Return an iterator over the RevokedCertificate objects

pub fn extensions(&self) -> &[X509Extension<'_>]

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

Get the CRL extensions.

pub fn crl_number(&self) -> Option<&BigUint>

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

Get the CRL number, if present

Note that the returned value is a BigUint, because of the following RFC specification:

Given the requirements above, CRL numbers can be expected to contain long integers.  CRL
verifiers MUST be able to handle CRLNumber values up to 20 octets.  Conformant CRL issuers
MUST NOT use CRLNumber values longer than 20 octets.

pub fn verify_signature( &self, public_key: &SubjectPublicKeyInfo<'_>, ) -> Result<(), X509Error>

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

Verify the cryptographic signature of this certificate revocation list

public_key is the public key of the signer.

Not all algorithms are supported, this function is limited to what ring supports.

pub fn as_raw(&self) -> &'a [u8]

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

Return the raw ASN.1 DER content of the complete signed certificate revocation list that was parsed.

This includes the to-be-signed (TBS) certificate list, the signature algorithm, and the signature. If you want just the ASN.1 DER of the TBS certificate list, prefer TbsCertList::as_ref().

We avoid the AsRef trait in this instance to ensure the full lifetime of the CertificateRevocationList is used.

impl CertificateRevocationList<'_>

pub fn walk<V>(&self, visitor: &mut V)

where V: CertificateRevocationListVisitor,

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

Run the provided CertificateRevocationListVisitor over the Certificate Revocation List (self)
