tag_insight = "The ntpd daemon is an implementation of the Network Time Protocol
(NTP) used to synchronize the time of a computer system to a reference
time source.

FreeBSD includes software from the OpenSSL Project.  The OpenSSL
Project is a collaborative effort to develop a robust,
commercial-grade, full-featured Open Source toolkit implementing the
Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1)
protocols as well as a full-strength general purpose cryptography
library.

The EVP_VerifyFinal() function from OpenSSL is used to determine if a
digital signature is valid.  When ntpd(8) is set to cryptographically
authenticate NTP data it incorrectly checks the return value from
EVP_VerifyFinal().";
