Description (partial)

After correctly configuring type 6 encryption (Master Key, activating Password Encryption feature) passwords/keys entered as Type 7 and requested to be re-encrypted will not re-encrypt

Additionally one or more of the following symptoms may be seen:
Master Key (as per show system internal sksd mkey detail) may be missing after switchover
Re-encryption may change a Type 7 password slightly, but it will not become Type 6
TACACS configuration becomes missing and the following error is seen on CLI:
"Could not get the ascii-display data from crypt-service. ?? Failure in encryption/decryption"

Issue only occurs for Type 6 (Master Key) Encryption

Switchover or VSM reload has been observed to be a trigger for some issues, however the exact triggers are as yet unknown
