◆ get()

std::shared_ptr< Atomic< size_t > > Botan::XMSS_Index_Registry::get	(	const secure_vector< uint8_t > &	private_seed,
		const secure_vector< uint8_t > &	prf )

Retrieves the last unused leaf index for the private key identified by private_seed and prf. The leaf index will be updated properly across independent copies of private_key.

Parameters

private_seed	Part of the unique identifier for an XMSS_PrivateKey.
prf	Part of the unique identifier for an XMSS_PrivateKey.

Returns: last unused leaf index for private_key.
