* initial relay side lns * fix typo * add reserved names and refactor test for dns * lns name decryption * all wired up (allegedly) * refact to use service::EncryptedName for LNS responses to include nonce with ciphertext * fully rwemove tag_lookup_job * replace lns cache with DecayingHashTable * check for lns name validity against the following rules: * not localhost.loki, loki.loki, or snode.loki * if it contains no dash then max 32 characters long, not including the .loki tld (and also assuming a leading subdomain has been stripped) * These are from general DNS requirements, and also enforced in registrations: * Must be all [A-Za-z0-9-]. (A-Z will be lower-cased by the RPC call). * cannot start or end with a - * max 63 characters long if it does contain a dash * cannot contain -- in the third and fourth characters unless it starts with xn-- * handle timeout in name lookup job by calling the right handler with std::nullopt
