Struct blsttc::SecretKeyShare
source · pub struct SecretKeyShare(_);
Expand description
A secret key share.
Serde integration
SecretKeyShare
implements Deserialize
but not Serialize
to avoid accidental
serialization in insecure contexts. To enable both use the ::serde_impl::SerdeSecret
wrapper which implements both Deserialize
and Serialize
.
Implementations§
sourcepub fn from_mut(fr: &mut Fr) -> Self
pub fn from_mut(fr: &mut Fr) -> Self
Creates a new SecretKeyShare
from a mutable reference to a field element. This
constructor takes a reference to avoid any unnecessary stack copying/moving of secrets
field elements. The field element will be copied bytewise onto the heap, the resulting
Box
is stored in the SecretKey
which is then wrapped in a SecretKeyShare
.
WARNING this constructor will overwrite the pointed to Fr
element with zeros once it
has been copied into a new SecretKeyShare
.
Returns the matching public key share.
sourcepub fn sign_g2<H: Into<G2Affine>>(&self, hash: H) -> SignatureShare
pub fn sign_g2<H: Into<G2Affine>>(&self, hash: H) -> SignatureShare
Signs the given element of G2
.
sourcepub fn sign<M: AsRef<[u8]>>(&self, msg: M) -> SignatureShare
pub fn sign<M: AsRef<[u8]>>(&self, msg: M) -> SignatureShare
Signs the given message.
Returns a decryption share, or None
, if the ciphertext isn’t valid.
Returns a decryption share, without validating the ciphertext.
sourcepub fn reveal(&self) -> String
pub fn reveal(&self) -> String
Generates a non-redacted debug string. This method differs from
the Debug
implementation in that it does leak the secret prime
field element.
sourcepub fn derive_child(&self, index: &[u8]) -> Self
pub fn derive_child(&self, index: &[u8]) -> Self
Derives a child secret key share for a given index.
sourcepub fn from_bytes(bytes: [u8; 32]) -> Result<Self>
pub fn from_bytes(bytes: [u8; 32]) -> Result<Self>
Deserializes from big endian bytes

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where D: Deserializer<'de>,
Can be used to create a new random instance of SecretKeyShare
. This is only useful for testing
purposes as such a key has not been derived from a SecretKeySet
.
