Expand description

X.509 Name (as used in Issuer and Subject fields)

The Name describes a hierarchical name composed of attributes, such as country name, and corresponding values, such as US. The type of the component AttributeValue is determined by the AttributeType; in general it will be a DirectoryString.

Implementations

Builds a new X509Name from the provided elements.

Attempt to format the current name, using the given registry to convert OIDs to strings.

Note: a default registry is provided with this crate, and is returned by the oid_registry() method.

Return an iterator over the RelativeDistinguishedName components of the name

Return an iterator over the RelativeDistinguishedName components of the name

Return an iterator over the attribute types and values of the name

Return an iterator over the components identified by the given OID

The type of the component AttributeValue is determined by the AttributeType; in general it will be a DirectoryString.

Attributes with same OID may be present multiple times, so the returned object is an iterator. Expected number of objects in this iterator are

  • 0: not found
  • 1: present once (common case)
  • 2 or more: attribute is present multiple times

Return an iterator over the CommonName attributes of the X.509 Name.

Returned iterator can be empty if there are no CommonName attributes. If you expect only one CommonName to be present, then using next() will get an Option<&AttributeTypeAndValue>.

A common operation is to extract the CommonName as a string.

use x509_parser::x509::X509Name;

fn get_first_cn_as_str<'a>(name: &'a X509Name<'_>) -> Option<&'a str> {
    name.iter_common_name()
        .next()
        .and_then(|cn| cn.as_str().ok())
}

Note that there are multiple reasons for failure or incorrect behavior, for ex. if the attribute is present multiple times, or is not a UTF-8 encoded string (it can be UTF-16, or even an OCTETSTRING according to the standard).

Return an iterator over the Country attributes of the X.509 Name.

Return an iterator over the Organization attributes of the X.509 Name.

Return an iterator over the OrganizationalUnit attributes of the X.509 Name.

Return an iterator over the StateOrProvinceName attributes of the X.509 Name.

Return an iterator over the Locality attributes of the X.509 Name.

Return an iterator over the EmailAddress attributes of the X.509 Name.
