- * \brief
- * The keytable module provides services for storing and retrieving DNSSEC
- * trusted keys, as well as the ability to find the deepest matching key
- * for a given domain name.
- *
- * MP:
- *\li The module ensures appropriate synchronization of data structures it
- * creates and manipulates.
- *
- * Resources:
- *\li TBS
- *
- * Security:
- *\li No anticipated impact.
