Module openssl::x509::extension

source ·
Expand description

Add extensions to an X509 certificate or certificate request.

The extensions defined for X.509 v3 certificates provide methods for associating additional attributes with users or public keys and for managing relationships between CAs. The extensions created using this module can be used with X509v3Context objects.

Example

use openssl::x509::extension::BasicConstraints;
use openssl::x509::X509Extension;

let mut bc = BasicConstraints::new();
let bc = bc.critical().ca().pathlen(1);

let extension: X509Extension = bc.build().unwrap();
