Struct Asn1Object

pub struct Asn1Object(/* private fields */);

Object Identifier

Represents an ASN.1 Object. Typically, NIDs, or numeric identifiers are stored as a table within the Nid module. These constants are used to determine attributes of a certificate, such as mapping the attribute “CommonName” to “CN” which is represented as the OID of 13. This attribute is a constant in the nid::COMMONNAME.

Implementations

impl Asn1Object

pub fn from_str(txt: &str) -> Result<Asn1Object, ErrorStack>

Constructs an ASN.1 Object Identifier from a string representation of the OID.

This corresponds to OBJ_txt2obj.

pub fn as_slice(&self) -> &[u8]

Return the OID as an DER encoded array of bytes. This is the ASN.1 value, not including tag or length.

Requires OpenSSL 1.1.1 or newer.

This corresponds to OBJ_get0_data.

Methods from Deref<Target = Asn1ObjectRef>

pub fn nid(&self) -> Nid

Returns the NID associated with this OID.
