Session keys runtime api.

Provided Methods

fn generate_session_keys(
    &self,
    __runtime_api_at_param__: &BlockId<Block>,
    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.

fn generate_session_keys_with_context(
    &self,
    __runtime_api_at_param__: &BlockId<Block>,
    context: ExecutionContext,
    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.

fn decode_session_keys(
    &self,
    __runtime_api_at_param__: &BlockId<Block>,
    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.

fn decode_session_keys_with_context(
    &self,
    __runtime_api_at_param__: &BlockId<Block>,
    context: ExecutionContext,
    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.
