[−][src]Struct sequoia_openpgp::packet::signature::Signature4
Holds a v4 Signature packet.
This holds a version 4 Signature packet. Normally, you won't
directly work with this data structure, but with the Signature
enum, which is version agnostic. An exception is when you need to
do version-specific operations. But currently, there aren't any
version-specific methods.
Implementations
impl Signature4
[src]
pub fn new(
typ: SignatureType,
pk_algo: PublicKeyAlgorithm,
hash_algo: HashAlgorithm,
hashed_area: SubpacketArea,
unhashed_area: SubpacketArea,
digest_prefix: [u8; 2],
mpis: Signature
) -> Self
[src]
typ: SignatureType,
pk_algo: PublicKeyAlgorithm,
hash_algo: HashAlgorithm,
hashed_area: SubpacketArea,
unhashed_area: SubpacketArea,
digest_prefix: [u8; 2],
mpis: Signature
) -> Self
Creates a new signature packet.
If you want to sign something, consider using the SignatureBuilder
interface.
pub fn pk_algo(&self) -> PublicKeyAlgorithm
[src]
Gets the public key algorithm.
pub fn digest_prefix(&self) -> &[u8; 2]
[src]
Gets the hash prefix.
pub fn mpis(&self) -> &Signature
[src]
Gets the signature packet's MPIs.
pub fn computed_digest(&self) -> Option<&[u8]>
[src]
Gets the computed hash value.
This is set by the PacketParser
when parsing the message.
pub fn level(&self) -> usize
[src]
Gets the signature level.
A level of 0 indicates that the signature is directly over the data, a level of 1 means that the signature is a notarization over all level 0 signatures and the data, and so on.
pub fn exportable(&self) -> Result<()>
[src]
Returns whether or not this signature should be exported.
This checks whether the Exportable Certification
subpacket
is absent or present and 1, and that the signature does not
include any sensitive Revocation Key
(designated revokers)
subpackets.
Methods from Deref<Target = SignatureFields>
pub fn version(&self) -> u8
[src]
Gets the version.
pub fn typ(&self) -> SignatureType
[src]
Gets the signature type.
This function is called typ
and not type
, because type
is a reserved word.
pub fn hash_algo(&self) -> HashAlgorithm
[src]
Gets the hash algorithm.

impl PartialEq<Signature4> for Signature4
[src]
fn eq(&self, other: &Signature4) -> bool
[src]
This method tests for self and other values to be equal, and is used by ==.
This method compares the serialized version of the two
packets. Thus, the computed values are ignored (level
,
computed_digest
).
Note: because this function also compares the unhashed
subpacket area, it is possible for a malicious party to take
valid signatures, add subpackets to the unhashed area,
yielding valid but distinct signatures. If you want to ignore
the unhashed area, you should instead use the
Signature4::normalized_eq
method.
