Enum sequoia_openpgp::Fingerprint

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

A long identifier for certificates and keys.

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

Note: This enum cannot be exhaustively matched to allow future extensions.

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.

Methods

impl Fingerprint

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

Reads a binary fingerprint.

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

Returns a reference to the raw Fingerprint.

pub fn to_hex(&self) -> String

Converts this fingerprint to its canonical hexadecimal representation.

This representation is always uppercase and without spaces and is suitable for stable key identifiers.

The output of this function is exactly the same as formatting this object with the :X format specifier.

use openpgp::Fingerprint;

let fpr = "0123 4567 89AB CDEF 0123 4567 89AB CDEF 0123 4567".parse::<Fingerprint>().unwrap();

assert_eq!("0123456789ABCDEF0123456789ABCDEF01234567", fpr.to_hex());
assert_eq!(format!("{:X}", fpr), fpr.to_hex());

pub fn from_hex(s: &str) -> Result<Self, Error>

Parses the hexadecimal representation of an OpenPGP fingerprint.

This function is the reverse of to_hex. It also accepts other variants of the fingerprint notation including lower-case letters, spaces and optional leading 0x.

use openpgp::Fingerprint;

let fpr = Fingerprint::from_hex("0123456789ABCDEF0123456789ABCDEF01234567").unwrap();

assert_eq!("0123456789ABCDEF0123456789ABCDEF01234567", fpr.to_hex());

let fpr = Fingerprint::from_hex("0123 4567 89ab cdef 0123 4567 89ab cdef 0123 4567").unwrap();

assert_eq!("0123456789ABCDEF0123456789ABCDEF01234567", fpr.to_hex());

pub fn to_icao(&self) -> String

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