GET request on REST endpoint /mgmt/tm/sys/file/ssl-key returns the incorrect value for passphrase.


Passphrase value is incorrect. Autoscale AWS deployments fail when trying to deploy a BIG-IP v14.1.2.5 or v14.1.2.6 AMI. This is the result of a change in how ssl-key passphrases are being returned in REST calls.


This occurs when getting the ssl-key information, and the key contains a passphrase. -- Using BIG-IP v14.1.2.5 or v14.1.2.6 to deploy Amazon Machine Image (AMI).



Fix Information

Can now deploy from BIG-IP v14.1.2.5 or v14.1.2.6 AMI when using passphrase from a GET request on REST endpoint /mgmt/tm/sys/file/ssl-key.

Behavior Change

Changes in REST framework from to GET request on REST endpoint /mgmt/tm/sys/file/ssl-key returns the the passphrase in a different format and also changes on every request.
