Struct Extension

Source
pub struct Extension<'a, O: Oid + 'a> { /* private fields */ }
Expand description

A certificate extension.

Implementations§

Source§

impl<'a, O: Oid + 'a> Extension<'a, O>

Source

pub fn regular(oid: O, value: &'a [u8]) -> Self

Constructs an extension.

If this extension is not recognized by a certificate-using system, it will be ignored.

oid is an OID that specifies the format and definitions of the extension.

value is the DER encoding of an ASN.1 value corresponding to the extension type identified by oid.

Source

pub fn critical(oid: O, value: &'a [u8]) -> Self

Constructs a critical extension.

If this extension is not recognized by a certificate-using system, the certificate will be rejected.

oid is an OID that specifies the format and definitions of the extension.

value is the DER encoding of an ASN.1 value corresponding to the extension type identified by oid.
