Session keys runtime api.

Provided Methods§

source

fn generate_session_keys( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, seed: Option<Vec<u8>>, ) -> Result<Vec<u8>, ApiError>

Generate a set of session keys with optionally using the given seed. The keys should be stored within the keystore exposed via runtime externalities.

The seed needs to be a valid utf8 string.

Returns the concatenated SCALE encoded public keys.

source

fn decode_session_keys( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, encoded: Vec<u8>, ) -> Result<Option<Vec<(Vec<u8>, KeyTypeId)>>, ApiError>

Decode the given public session keys.

Returns the list of public raw public keys + key type.
