Member Function Documentation

virtual Sr25519KeypairAndSeed kagome::crypto::Sr25519Provider::generateKeypair ( ) const

pure virtual

Generates random keypair for signing the message

Implemented in kagome::crypto::Sr25519ProviderImpl.

virtual Sr25519Keypair kagome::crypto::Sr25519Provider::generateKeypair ( const Sr25519Seed &  seed ) const

pure virtual

Generate random keypair from seed

Implemented in kagome::crypto::Sr25519ProviderImpl.

virtual outcome::result<Sr25519Signature> kagome::crypto::Sr25519Provider::sign ( const Sr25519Keypair &  keypair, gsl::span< const uint8_t >  message  ) const

pure virtual

Sign message

Parameters

msg	using
keypair.	If computed value is less than
threshold	then return optional containing this value and proof. Otherwise none returned
keypair	pair of public and secret sr25519 keys
message	bytes to be signed

Returns

signed message

Implemented in kagome::crypto::Sr25519ProviderImpl.

virtual outcome::result<bool> kagome::crypto::Sr25519Provider::verify ( const Sr25519Signature &  signature, gsl::span< const uint8_t >  message, const Sr25519PublicKey &  public_key  ) const

pure virtual

Verifies that

Parameters

message	was derived using
public_key	on
signature

Implemented in kagome::crypto::Sr25519ProviderImpl.
