Methods

impl SignaturePacket

pub fn new(
    sig_type: SignatureType,
    pubkey_algo: PublicKeyAlgorithm,
    hash_algo: HashAlgorithm
) -> Result<SignaturePacket, Error>

Create a new signature with the given parameters. The new signature's creation time will be set to the current system time, and the contents will be empty.

pub fn contents(&self) -> Result<Signature, Error>

Retrieve the contents of this signature. For RSA signatures, this is a single multiprecision integer representing m^d mod n; for DSA signatures this is two multiprecision integers representing r and s.

pub fn set_contents(&mut self, sig: Signature) -> Result<(), Error>

Set the contents of this signature.

pub fn timestamp(&self) -> Option<Duration>

Retrive the creation time of this signature.

pub fn set_timestamp(&mut self, timestamp: Duration)

Set the creation time of this signature.

pub fn signer(&self) -> Option<u64>

Retrieve the key ID of this signature's issuer.

pub fn set_signer(&mut self, signer: u64)

Set the key ID of this signature's issuer.

pub fn preferred_hash_algorithms(&self) -> Option<Vec<HashAlgorithm>>

Retrieve the preferred hash algorithms of this signature.

pub fn set_preferred_hash_algorithms<T: AsRef<[HashAlgorithm]>>(
    &mut self,
    algos: T,
    hashed: bool
)

Set the preferred hash algorithms of this signature. If hashed is true, this subpacket will be added as a hashed subpacket.

pub fn signable_payload<T: AsRef<[u8]>>(
    &self,
    payload: T
) -> Result<Vec<u8>, Error>

Build a payload suitable for signing.

Note that this payload must be placed in an ASN.1 DigestInfo structure prior to signing, which is outside the scope of this library.

pub fn header(&self) -> Result<Vec<u8>, Error>

Retrieve the header for this signature, i.e. everything except the MPI contents of the signature.

pub fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serialize this signature to bytes.

pub fn from_bytes(bytes: &[u8]) -> Result<SignaturePacket, Error>

Read in a signature from some bytes.

Trait Implementations

impl Clone for SignaturePacket

fn clone(&self) -> SignaturePacket

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SignaturePacket

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.
