23f1535d6a60817d2846bac0aea230ea475d7dccminfrin (default), HMAC-SHA384 and HMAC-SHA512.
23f1535d6a60817d2846bac0aea230ea475d7dccminfrin They use a shared secret on each end of the connection.

23f1535d6a60817d2846bac0aea230ea475d7dccminfrin Normally, <span><strong class="command">named</strong></span> will periodically
23f1535d6a60817d2846bac0aea230ea475d7dccminfrin test to see whether data below an NTA can now be
23f1535d6a60817d2846bac0aea230ea475d7dccminfrin validated (see the <code class="option">nta-recheck</code> option
23f1535d6a60817d2846bac0aea230ea475d7dccminfrin in the Administrator Reference Manual for details).
23f1535d6a60817d2846bac0aea230ea475d7dccminfrin If data can be validated, then the NTA is regarded as
23f1535d6a60817d2846bac0aea230ea475d7dccminfrin no longer necessary, and will be allowed to expire
23f1535d6a60817d2846bac0aea230ea475d7dccminfrin early. The <code class="option">-force</code> overrides this
23f1535d6a60817d2846bac0aea230ea475d7dccminfrin behavior and forces an NTA to persist for its entire
e2f3f3a981b845a0f26efacbe145659a63240944jailletc lifetime, regardless of whether data could be
23f1535d6a60817d2846bac0aea230ea475d7dccminfrin validated if the NTA were not present.
