Enum sequoia_openpgp::Fingerprint

pub enum Fingerprint {
    V4([u8; 20]),
    Invalid(Box<[u8]>),
}

Holds a fingerprint.

A fingerprint uniquely identifies a public key. For more details about how a fingerprint is generated, see Section 12.2 of RFC 4880.

Variants

V4([u8; 20])

20 byte SHA-1 hash.

Invalid(Box<[u8]>)

Used for holding fingerprints that we don't understand. For instance, we don't grok v3 fingerprints. And, it is possible that the Issuer subpacket contains the wrong number of bytes.

Methods

impl Fingerprint

pub fn from_bytes(raw: &[u8]) -> Fingerprint

Reads a binary fingerprint.

pub fn from_hex(hex: &str) -> Result<Fingerprint>

Reads a hexadecimal fingerprint.

This function ignores whitespace.

Example

let hex = "3E8877C877274692975189F5D03F6F865226FE8B";
let fp = Fingerprint::from_hex(hex);
assert!(fp.is_ok());
assert_eq!(fp.unwrap().to_hex(), hex);

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

Returns a reference to the raw Fingerprint.

pub fn to_string(&self) -> String

Converts the fingerprint to its standard representation.

Returns the fingerprint suitable for human consumption.

pub fn to_hex(&self) -> String

Converts the fingerprint to a hexadecimal number.

pub fn to_keyid(&self) -> KeyID

Converts the fingerprint to a key ID.

pub fn to_icao(&self) -> String

Converts the hex representation of the fingerprint to a phrase in the ICAO alphabet.
