Function Documentation

hs_cache_lookup_as_client()

const hs_descriptor_t* hs_cache_lookup_as_client

(

const ed25519_public_key_t *

key

)

Public API: Given the HS ed25519 identity public key in key, return its HS descriptor if it's stored in our cache, or NULL if not.

hs_cache_lookup_encoded_as_client()

const char* hs_cache_lookup_encoded_as_client

(

const ed25519_public_key_t *

key

)

Public API: Given the HS ed25519 identity public key in key, return its HS encoded descriptor if it's stored in our cache, or NULL if not.

hs_cache_store_as_client()

int hs_cache_store_as_client	(	const char *	desc_str,
		const ed25519_public_key_t *	identity_pk
	)

Public API: Given an encoded descriptor, store it in the client HS cache. Return -1 on error, 0 on success .
