Struct OpenpgpSignature

pub struct OpenpgpSignature {
    pub(crate) detached: DetachedSignature,
    pub(crate) source: Option<PathBuf>,
}

A detached OpenPGP signature for use in VOA verification.

Fields

detached: DetachedSignature

source: Option<PathBuf>

The file that this signature was loaded from

Implementations

impl OpenpgpSignature

pub fn from_file<P: AsRef<Path>>(path: P) -> Result<Self, Error>

Creates an OpenpgpSignature from the file in path.

Errors

Returns an error:

• If path can’t be read
• If an OpenpgpSignature cannot be parsed from the content of the file

pub(crate) fn from_slice(data: &[u8]) -> Result<Self, Error>

Creates an OpenpgpSignature from data.

Errors

Returns an error, if an OpenpgpSignature cannot be parsed from data.

pub fn creation_time(&self) -> Option<SystemTime>

Returns the creation time.

Considering the creation time of a detached OpenPGP signature prevents attacks where a signature claims to be very old, and thereby is allowed to use a weak cryptographic mechanism.

Note

Users of OpenpgpSignature are advised to discard signatures, if their creation time is implausible, e.g. if a signature claims to be older than the data, that it claims to be over.

Errors

Returns an error if no creation time is found.

pub fn source(&self) -> Option<&Path>

The source file that this signature was loaded from, if known

pub(crate) fn verifiable_with(&self, verifier: &SignatureVerifier) -> bool

Returns true if verifier matches any Issuer or IssuerFingerprint subpacket in this OpenpgpSignature.

Trait Implementations

impl Clone for OpenpgpSignature

fn clone(&self) -> OpenpgpSignature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpenpgpSignature

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

Formats the value using the given formatter.

impl PartialEq for OpenpgpSignature

fn eq(&self, other: &OpenpgpSignature) -> 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.
