Crate webpki 

webpki: Web PKI X.509 Certificate Validation.

See EndEntityCert’s documentation for a description of the certificate processing steps necessary for a TLS connection.

Features

Feature	Description
alloc	Enable features that require use of the heap. Currently all RSA signature algorithms require this feature.
std	Enable features that require libstd. Implies alloc.

Structs

AddrParseError

An error indicating that an IpAddrRef could not built because the input could not be parsed as an IP address.

BorrowedCertRevocationList

Borrowed representation of a RFC 5280 profile Certificate Revocation List (CRL).

BorrowedRevokedCert

Borrowed representation of a RFC 5280 profile Certificate Revocation List (CRL) revoked certificate entry.

Cert

A parsed X509 certificate.

DnsName

Requires the alloc feature. A DNS Name suitable for use in the TLS Server Name Indication (SNI) extension and/or for use as the reference hostname for which to verify a certificate.

DnsNameRef

A reference to a DNS Name suitable for use in the TLS Server Name Indication (SNI) extension and/or for use as the reference hostname for which to verify a certificate.

EndEntityCert

An end-entity certificate.

InvalidDnsNameError

An error indicating that a DnsNameRef could not built because the input is not a syntactically-valid DNS Name.

InvalidSubjectNameError

An error indicating that a SubjectNameRef could not built because the input is not a syntactically-valid DNS Name or IP address.

KeyUsage

The expected key usage of a certificate.

OwnedCertRevocationList

Owned representation of a RFC 5280 profile Certificate Revocation List (CRL).

OwnedRevokedCert

Owned representation of a RFC 5280 profile Certificate Revocation List (CRL) revoked certificate entry.

SignatureAlgorithm

A signature algorithm.

Time

The time type.

TlsClientTrustAnchorsDeprecated

Trust anchors which may be used for authenticating clients.

TlsServerTrustAnchorsDeprecated

Trust anchors which may be used for authenticating servers.

TrustAnchor

A trust anchor (a.k.a. root CA).

Enums

EndEntityOrCa

An enumeration indicating whether a Cert is a leaf end-entity cert, or a linked list node from the CA Cert to a child Cert it issued.

Error

An error that occurs during certificate validation or name validation.

IpAddr

Either a IPv4 or IPv6 address, plus its owned string representation

IpAddrRef

Either a IPv4 or IPv6 address, plus its borrowed string representation

RevocationReason

Identifies the reason a certificate was revoked. See RFC 5280 §5.3.1[^1]

SubjectNameRef

A DNS name or IP address, which borrows its text representation.
