Enum sequoia_openpgp::KeyID

pub enum KeyID {
    V4([u8; 8]),
    Invalid(Box<[u8]>),
    // some variants omitted
}

A short identifier for certificates and keys.

A KeyID is a fingerprint fragment. It identifies a public key, but is easy to forge. For more details about how a KeyID is generated, see Section 12.2 of RFC 4880.

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

Variants

V4([u8; 8])

Lower 8 byte SHA-1 hash.

Invalid(Box<[u8]>)

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

Methods

impl KeyID

pub fn new(data: u64) -> KeyID

Converts a u64 to a KeyID.

pub fn as_u64(&self) -> Result<u64>

Converts the KeyID to a u64 if possible.

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

Reads a binary key ID.

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

Returns a reference to the raw KeyID.

pub fn wildcard() -> Self

Returns the wildcard KeyID.

pub fn is_wildcard(&self) -> bool

Returns true if this is a wild card ID.

pub fn to_hex(&self) -> String

Converts this key ID 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::KeyID;

let keyid = "fb3751f1587daef1".parse::<KeyID>().unwrap();

assert_eq!("FB3751F1587DAEF1", keyid.to_hex());
assert_eq!(format!("{:X}", keyid), keyid.to_hex());

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

Parses the hexadecimal representation of an OpenPGP key ID.

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

use openpgp::KeyID;

let keyid = KeyID::from_hex("0xfb3751f1587daef1").unwrap();

assert_eq!("FB3751F1587DAEF1", keyid.to_hex());
