[−][src]Enum sequoia_openpgp::Fingerprint
A long identifier for certificates and keys.
A Fingerprint
uniquely identifies a public key.
Currently, Sequoia supports version 4 fingerprints and Key IDs only. Version 3 fingerprints and Key IDs were deprecated by RFC 4880 in 2007.
Essentially, a v4 fingerprint is a SHA-1 hash over the key's public key packet. For details, see Section 12.2 of RFC 4880.
Fingerprints are used, for example, to reference the issuing key
of a signature in its IssuerFingerprint
subpacket. As a
general rule of thumb, you should prefer using fingerprints over
KeyIDs because the latter are vulnerable to birthday attacks.
Note: This enum cannot be exhaustively matched to allow future extensions.
Examples
use openpgp::Fingerprint; let fp: Fingerprint = "0123 4567 89AB CDEF 0123 4567 89AB CDEF 0123 4567".parse()?; assert_eq!("0123456789ABCDEF0123456789ABCDEF01234567", fp.to_hex());
Variants (Non-exhaustive)
A 20 byte SHA-1 hash of the public key packet as defined in the RFC.
Used for holding fingerprint data that is not a V4 fingerprint, e.g. a V3 fingerprint (deprecated) or otherwise wrong-length data.
Implementations
impl Fingerprint
[src]
pub fn from_bytes(raw: &[u8]) -> Fingerprint
[src]
Creates a Fingerprint
from a byte slice in big endian
representation.
Examples
use openpgp::Fingerprint; let fp: Fingerprint = "0123 4567 89AB CDEF 0123 4567 89AB CDEF 0123 4567".parse()?; let bytes = [0x01, 0x23, 0x45, 0x67, 0x89, 0xAB, 0xCD, 0xEF, 0x01, 0x23, 0x45, 0x67, 0x89, 0xAB, 0xCD, 0xEF, 0x01, 0x23, 0x45, 0x67]; assert_eq!(Fingerprint::from_bytes(&bytes), fp);
pub fn as_bytes(&self) -> &[u8]
[src]
Returns the raw fingerprint as a byte slice in big endian representation.
Examples
use openpgp::Fingerprint; let fp: Fingerprint = "0123 4567 89AB CDEF 0123 4567 89AB CDEF 0123 4567".parse()?; assert_eq!(fp.as_bytes(), [0x01, 0x23, 0x45, 0x67, 0x89, 0xAB, 0xCD, 0xEF, 0x01, 0x23, 0x45, 0x67, 0x89, 0xAB, 0xCD, 0xEF, 0x01, 0x23, 0x45, 0x67]);
pub fn to_hex(&self) -> String
[src]
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 fp: Fingerprint = "0123 4567 89AB CDEF 0123 4567 89AB CDEF 0123 4567".parse()?; assert_eq!("0123456789ABCDEF0123456789ABCDEF01234567", fp.to_hex()); assert_eq!(format!("{:X}", fp), fp.to_hex());
pub fn from_hex(s: &str) -> Result<Self, Error>
[src]
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 fp = Fingerprint::from_hex("0123456789ABCDEF0123456789ABCDEF01234567")?; assert_eq!("0123456789ABCDEF0123456789ABCDEF01234567", fp.to_hex()); let fp = Fingerprint::from_hex("0123 4567 89ab cdef 0123 4567 89ab cdef 0123 4567")?; assert_eq!("0123456789ABCDEF0123456789ABCDEF01234567", fp.to_hex());
pub fn to_icao(&self) -> String
[src]
Converts the hex representation of the Fingerprint
to a
phrase in the ICAO spelling alphabet.
Examples
use openpgp::Fingerprint; let fp: Fingerprint = "01AB 4567 89AB CDEF 0123 4567 89AB CDEF 0123 4567".parse()?; assert!(fp.to_icao().starts_with("Zero One Alfa Bravo"));
