Description (partial)

This Bug tracks the Enhancement request for Nexus NTP to support stronger Authentication mechanisms. Currently the only mechanism is Message Digest 5 (MD5). 

It's proposed for better device security that the Nexus should support symmetric keys that use SHA-256, SHA-512 or AES-128.

Currently the MD5 is the only NTP authentication mechanism available on all Nexus switches.
