Struct Fingerprint 

pub struct Fingerprint { /* private fields */ }

A Fingerprint is a deterministic, fixed-length SHA-256 hash that uniquely identifies a single issued Certificate.

The fingerprint is constructed by hashing the (DER encoded) bytes of a Certificate, a process that is lightly described in RFC 4387 § 2.2 as a certHash. Unlike the RFC, we use SHA-256 as the hash instead of SHA-1 (a common modification for newer systems, including new versions of OpenSSL).

A Fingerprint should be used when checking if two certificates are identical.

Implementations

impl Fingerprint

pub fn as_hex_str(&self) -> &str

Render the Fingerprint as a lowercase hex string delimited by colons in the style of OpenSSL.

Example: cc:cb:0f:63:f1:63:5e:f1:0e:26:e8:82:f7:7a:6e:f9

This value is lazily rendered and cached for reuse.

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

Return the raw fingerprint digest bytes.

Trait Implementations

impl Clone for Fingerprint

fn clone(&self) -> Fingerprint

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Fingerprint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Fingerprint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Fingerprint

impl<'a> From<&'a X509Certificate<'a>> for Fingerprint

fn from(cert: &'a X509Certificate<'a>) -> Self

Converts to this type from the input type.

impl Hash for Fingerprint

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Fingerprint

fn eq(&self, other: &Fingerprint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for Fingerprint

impl Valuable for Fingerprint

Render a Fingerprint as an encoded string in structured logging.

fn as_value(&self) -> Value<'_>

Converts self into a Value instance.

fn visit(&self, visit: &mut dyn Visit)

Calls the relevant method on Visit to extract data from self.

fn visit_slice(slice: &[Self], visit: &mut dyn Visit)

where Self: Sized,

Calls Visit::visit_primitive_slice() with self.
